Parameters

interface-type interface-number: Specifies an interface by its type and number.

service-instance instance-id: Specifies an Ethernet service instance by its ID in the range of 1 to 4096.

access-mode: Specifies an access mode. The default access mode varies by AC type.

· If the AC is a Layer 3 interface, the default access mode is as follows:

¡ For a VLAN interface, the default access mode is VLAN.

¡ For a Layer 3 subinterface, the default access mode is VLAN.

¡ For a Layer 3 interface of another type, the default access mode is Ethernet.

· If the AC is an Ethernet service instance, the default access mode is Ethernet.

ethernet: Specifies the Ethernet access mode.

vlan: Specifies the VLAN access mode.

track track-entry-number&<1-3>: Specifies a space-separated list of up to three track entry numbers in the range of 1 to 1024. The AC is up only if a minimum of one associated track entry is in positive state.

access-evpn: Uses the specified L2VE interface to access an EVPN VPWS or EVPN VPLS network. This keyword takes effect only when the specified interface is an L2VE interface. If the specified L2VE interface is used for communication between an L2VPN network and an L3VPN network, do not specify this keyword.

Usage guidelines

After you execute this command, packets received from the mapped Layer 3 interface or Ethernet service instance are forwarded to the PW or another AC bound to the cross-connect.

To configure this command for an Ethernet service instance, you must first use the encapsulation command to configure a frame match criterion for the Ethernet service instance.

The access mode determines how the PE treats the VLAN tag in Ethernet frames received from the AC. It also determines how the PE forwards Ethernet frames out of the AC.

· VLAN access mode—Ethernet frames received from the AC must carry a VLAN tag in the Ethernet header. The VLAN tag is called a P-tag, which is assigned by the service provider. Ethernet frames sent out of the AC must also carry the P-tag.

· Ethernet access mode—If Ethernet frames from the AC have a VLAN tag in the header, the VLAN tag is called a U-tag, and the PE ignores it. Ethernet frames sent out of the AC do not carry the P-tag.

Usage guidelines

In an EVPN network with distributed gateways, you can disable ARP information advertisement for a VXLAN to save resources if all its user terminals use the same EVPN gateway device. The EVPN instance of the VXLAN will stop advertising ARP information through MAC/IP advertisement routes and withdraw advertised ARP information. When ARP information advertisement is disabled, user terminals in other VXLANs still can communicate with that VXLAN through IP prefix advertisement routes.

In an EVPN VPLS network, you can disable ARP information advertisement to save resources if all its user terminals are attached to the same PE. The PE will stop advertising ARP information and withdraw advertised ARP information.

Parameters

instance instance-name: Specifies a BGP instance by its name, a case-sensitive string of 1 to 31 characters. If you do not specify this option, the command displays route targets for the default BGP instance.

Usage guidelines

Use this command to display the following information:

· ES-import route targets carried in the ES-Import Route Target extended community attribute.

· Route targets configured for all EVPN instances created in system view and VSI view.

The ES-Import Route Target extended community attribute is advertised with ES routes. An ES-import route target carried in this attribute is a 48-bit string that is automatically generated in the H-H-H format based on an ESI. The device accepts an ES route only if the ES-import route target carried in that route matches an ES-import route target created based on a local ESI.

In the command output, the route targets enumerated for each route target type cannot exceed 8191 bytes. Each character is one byte long. For example, 1:1 are three bytes. If this limit is reached, excess characters are replaced with three dots (…).

Usage guidelines

In an EVPN VPLS or VPLS over SRv6 network, EVPN E-tree isolates unicast and flood traffic (broadcast, multicast, and unknown unicast) of ACs in the same EVPN instance based on the AC roles. With EVPN E-tree, the device isolates unicast and flood traffic of ACs in the same EVPN instance as follows:

· Leaf ACs can access root ACs.

· Leaf ACs cannot access each other.

· Root ACs can access each other and access leaf ACs.

Inter-site EVPN E-tree controls communication between local ACs and remote ACs. You do not need to enable this feature if you want to control communication between local ACs.

You cannot configure inter-site EVPN E-tree for both EVPN VPLS and EVPN VPLS over SRv6.

Parameters

esi-id: Specifies an ES by its ESI in XXXX.XXXX.XXXX.XXXX.XXXX format. Each X represents a hexadecimal digit. The ESI must begin with 00 and cannot be all zeros.

Usage guidelines

An ESI uniquely identifies an ES. The links on interfaces, UPWs, or VSIs with the same ESI belong to the same ES. Traffic of the ES can be distributed among the links for load sharing.

You can assign ESIs to a main interface and its subinterfaces.

· If you assign an ESI to a subinterface, the subinterface-specific ESI and ES configuration take precedence over those configured on the main interface. The ES configuration includes the following:

¡ evpn redundancy-mode.

¡ evpn df-election algorithm.

¡ evpn df-election preference.

¡ evpn df-election preference non-revertive.

¡ evpn timer es-delay.

· If you do not assign an ESI to a subinterface, it inherits the ESI and ES configuration (if configured) of the main interface. In this scenario, the ES configuration on the subinterface does not take effect.

You can assign an ESI to a VSI LDP PW or VSI static PW only if you specify the dci or no-split-horizon keyword in executing the peer command for the PW.

PEs at a multihomed site send UMRs that carry the ESIs configured in VSI view.

To modify the ESI of an interface, UPW, or VSI, first use the undo esi command to delete the original ESI.

Parameters

Algorithm: Specifies a DF election algorithm. The value of this argument can only be preference, which represents the preference-based algorithm.

Usage guidelines

At a multihomed EVPN network site, you can modify the DF election algorithm with this command to control the DF election result.

You can configure the DF election algorithm in system view and in interface view. The global DF election algorithm takes effect on all ESs, and the interface-specific DF election algorithm takes effect only on the ESs on an interface. The interface-specific DF election algorithm takes precedence over the global DF election algorithm.

undo evpn df-election preference non-revertive

Default

Non-revertive mode is disabled for preference-based DF election.

Views

Interface view

Predefined user roles

network-admin

Usage guidelines

Preference-based DF election selects the device with the highest preference as the DF. The BDF takes over the DF role if one of the following events occurs:

· The DF fails.

· The site-facing link on the DF fails.

· The DF election preference of the BDF is set to be higher than that of the DF.

When the original DF or its site-facing link recovers, or its preference is set to be higher than that of the new DF, the original DF will take over the DF role. To avoid undesired traffic loss, you can disable reversion to the original DF by enabling non-revertive mode for preference-based DF election.

This command takes effect after the evpn df-election algorithm preference command is executed in interface view or system view.

Examples

# Enable non-revertive mode for preference-based DF election.

Views

System view

Predefined user roles

network-admin

Parameters

group-ipv4: Specifies the virtual IPv4 ED address.

group-ipv6: Specifies the virtual IPv6 ED address.

Usage guidelines

For high availability and load sharing, you can deploy two EDs at a data center. To virtualize the redundant EDs into one device, you must configure the same virtual ED address on them. The redundant EDs use the virtual ED address to establish tunnels with VTEPs and remote EDs.

Redundant EDs cannot provide access service for local VMs. They can act only as EDs. For correct communication, do not redistribute external routes on only one of the redundant EDs. However, you can redistribute the same external routes on both EDs.

On a redundant ED, the virtual ED address must be the IP address of a loopback interface, and it cannot be the BGP peer IP address of the ED.

This command is applicable only to an EVPN-DCI network, and it cannot take effect on an EVPN L3VPN network.

If you execute the undo bgp command to disable the BGP instance of the EVPN address family, the evpn edge group setting will also be deleted. Make sure you are fully aware of the impact of the undo bgp command when you use it on a live network.

Examples

# Configure 1.2.3.4 as the virtual ED address.

Parameters

mpls: Specifies MPLS encapsulation.

vxlan: Specifies VXLAN encapsulation.

instance-name: Specifies an EVPN instance by its name, a case-sensitive string of 1 to 31 characters.

vsi-tag: Specifies a VSI tag ID. An EVPN instance uses tag IDs to identify VSIs when it is bound to multiple VSIs. If you do not specify a tag ID, the tag ID 0 is assigned to the VSI.

tag-id: Specifies a tag ID. For VXLAN encapsulation, the value range for this argument is 1 to 16777215. For MPLS encapsulation, the value range for this argument is 1 to 4094.

auto-vxlan: Automatically generates a tag ID based on the VXLAN ID of the VSI.

Usage guidelines

This command is applicable only to EVPN VXLAN and EVPN VPLS.

You can bind a VSI to one or two EVPN instances. If you bind two EVP instances to a VSI, make sure one EVPN instance uses MPLS encapsulation and the other uses VXLAN encapsulation.

This command is mutually exclusive with the evpn encapsulation command. You cannot use them together on the same VSI.

Usage guidelines

Local FRR enables two PEs at a multihomed EVPN VPWS network site to set up a bypass PW between them. This feature helps reduce the traffic loss caused by AC failure.

At a multihomed EVPN VPWS network site, CE 1 is dualhomed to PE 1 and PE 2, and PE 1 is the DF. When the AC on PE 1 fails, PE 1 advertises the local unreachable event to PE 2 and remote PEs for the remote PEs to switch traffic to the PWs to PE 2. In this situation, PE 1 drops the packets that the remote PEs send before they are notified of the local unreachable event. To resolve this issue, enable local FRR on PE 1 and PE 2. When receiving packets from the remote PEs after its AC fails, PE 1 forwards the packets to PE 2 over the bypass PW to prevent traffic loss.

On an EVPN instance, EVPN instance-specific local FRR configuration takes precedence over global local FRR configuration.

Usage guidelines

Local FRR enables two PEs at a multihomed EVPN VPLS network site to set up a PW between them. This feature helps reduce the traffic loss caused by AC failure.

At a multihomed EVPN VPLS network site, CE 1 is dualhomed to PE 1 and PE 2, and PE 1 is the DF. When the AC on PE 1 fails, PE 1 deletes the related MAC address entries and advertises the local unreachable event to PE 2 and remote PEs. Then, the remote PEs will switch traffic to the tunnels to PE 2. In this situation, PE 1 drops the packets that the remote PEs send before they are notified of the local unreachable event as the AC's MAC address entries have been deleted. To resolve this issue, enable local FRR on PE 1. If an AC fails, PE 1 changes the outgoing interface of the AC's MAC address entries to the index of the PW between PE 1 and PE 2. When receiving packets from remote PEs after its AC fails, PE 1 forwards the packets to PE 2 over the PW to prevent traffic loss.

Local FRR enables two VTEPs at a multihomed EVPN VXLAN network site to set up a VXLAN tunnel between them. This feature helps reduce the traffic loss caused by AC failure.

At a multihomed EVPN VXLAN network site, VM 1 is dualhomed to VTEP 1 and VTEP 2, and VTEP 1 is the DF. When the AC on VTEP 1 fails, VTEP 1 deletes the related MAC address entries and advertises the local unreachable event to VTEP 2 and remote VTEPs. Then, the remote VTEPs will switch traffic to the tunnels to VTEP 2. In this situation, VTEP 1 drops the packets that the remote VTEPs send before they are notified of the local unreachable event as the AC's MAC address entries have been deleted. To resolve this issue, enable local FRR on VTEP 1. If an AC fails, VTEP 1 changes the outgoing interface of the AC's MAC address entries to the index of the tunnel between VTEP 1 and VTEP 2. When receiving packets from remote VTEPs after its AC fails, VTEP 1 forwards the packets to VTEP 2 over the VXLAN tunnel to prevent traffic loss.

On an EVPN instance using MPLS encapsulation, EVPN instance-specific local FRR setting takes precedence over the global local FRR setting configured by using the evpn multihoming vpls-frr local command.

Usage guidelines

Remote FRR enables two PEs on an EVPN VPWS or EVPN VPWS over SRv6 network to set up a primary PW and a backup PW between them to ensure high availability. The PEs use the primary PW to forward traffic as long as it is available. When the primary PW fails, the PEs switch traffic to the backup PW.

Remote FRR is supported by a cross-connect group EVPN instance that uses MPLS or SRv6 encapsulation.

On an EVPN instance, EVPN instance-specific remote FRR configuration takes precedence over global remote FRR configuration.

Parameters

local-service-id: Specifies a local service ID in the range of 1 to 16777215.

remote-service-id: Specifies a remote service ID in the range of 1 to 16777215.

tunnel-policy tunnel-policy-name: Specifies a tunnel policy by its name, a case-sensitive string of 1 to 126 characters. If you do not specify a tunnel policy, the PW uses the default tunnel policy.

pw-class class-name: Specifies a PW class by its name, a case-sensitive string of 1 to 19 characters. You can specify a PW class to configure the PW data encapsulation type and control word for the PW. If you do not specify a PW class, the PW data encapsulation type is determined by the link type of the interface. The control word feature is not supported for PW data encapsulation types that do not require using control word.

Usage guidelines

You can use the evpn local-service-id remote-service-id command to concatenate two EVPN PWs on the same cross-connect.

To modify an EVPN PW, first use the undo evpn local-service-id remote-service-id command to delete the original EVPN PW.

If you set up an EVPN PW with a redundant PE at the local site, the device uses the BFD configuration in the PW class specified in the evpn local-service-id remote-service-id command.

· If the EVPN PW is a primary EVPN PW, the device establishes a dynamic BFD session for the EVPN PW.

· If the EVPN PW is a backup or ECMP EVPN PW, the device does not establish a dynamic BFD session for the EVPN PW.

Views

System view

Predefined user roles

network-admin

network-operator

Parameters

check-interval interval: Sets the detection interval for EVPN MAC moves in seconds. The value range is 0 or 10 to 3600. A value of 0 indicates that the device does not detect EVPN MAC moves.

threshold threshold: Sets the maximum number of MAC moves for each MAC address within a detection interval. The value range is 1 to 255. If you do not configure this parameter, the default value 12 applies.

Usage guidelines

Application scenarios

In an EVPN network, if multiple user devices attached to the PE are assigned the same MAC address, the PE will repeatedly report learning of the same local EVPN MAC address. The MAC address is considered to be constantly migrating between interfaces.

Within a detection interval, if the PE detects that the migration frequency of a certain MAC address exceeds the report suppression threshold, it will suppress the reporting of the locally learned EVPN MAC address information.

Restrictions and guidelines

If the detection interval is set to 0, reporting of local MAC moves for EVPN is not suppressed. The PE is allowed to report the locally learned EVPN MAC address information.

Usage guidelines

This command enables devices to exchange the routes of a VPN instance by using IP prefix advertisement routes with MPLS encapsulation. After you execute this command for a VPN instance, the device advertises the routes of the VPN instance through IP prefix advertisement routes. When receiving IP prefix advertisement routes with MPLS encapsulation, the device adds the routes that belong to the VPN instance to the routing table.

For EVPN to add MPLS encapsulation to IP prefix advertisement routes, you must execute the peer advertise encap-type mpls command in BGP EVPN address family view.

Examples

# Enable EVPN to advertise the IPv4 routes of VPN instance vpna.

Predefined user roles

network-admin

Usage guidelines

Use this command on the redundant PEs or VTEPs at a dualhomed site.

This command enables the device to do the following:

· Withdraw the Ethernet auto-discovery routes and MAC/IP advertisement routes that have been advertised.

· Set the Ethernet tag to 0 for the Ethernet auto-discovery routes and MAC/IP advertisement routes and re-advertise them.

After you configure ESIs for ACs on the redundant edge devices at a dualhomed site, the edge devices advertise Ethernet auto-discovery routes and MAC/IP advertisement routes that carry Ethernet tags. If the remote peers are unable to identify Ethernet tags, you must execute this command on the redundant edge devices to enable communication with the peers.

When you use this command, follow these restrictions and guidelines:

· After you assign an ESI to a Layer 2 Ethernet or aggregate interface, you must map the Ethernet service instances created on the interface to different VSIs. If two interfaces use the same ESI, you must map the Ethernet service instances created on them to different VSIs.

· After you assign an ESI to a Layer 3 main interface, its subinterfaces inherit the ESI if they do not have one. In addition, you must map two subinterfaces to different VSIs if the subinterfaces have the same ESI.

Usage guidelines

This command helps reduce the traffic loss caused by AC failure at a dualhomed EVPN VPLS network site.

At a multihomed EVPN VPLS network site, CE 1 is dualhomed to PE 1 and PE 2 through an aggregate link or smart trunk, and PE 3 is at a remote site. PE 1 forwards all traffic sent from CE 1 to the remote site, and PE 3 forwards the traffic that the remote site sends to CE 1 to both PE 1 and PE 2. When the AC on PE 1 fails, PE 1 withdraws the MAC/IP advertisement routes advertised to PE 2 and PE 3. In this situation, PE 3 does not have MAC address entries for CE 1 until PE 2 learns MAC address entries for CE 1 and advertises them to PE 3. As a result, traffic interruption occurs.

To resolve this issue, execute the evpn multihoming re-originated mac command on both PE 1 and PE 2. When receiving the MAC/IP advertisement routes advertised by PE 1, PE 2 generates MAC address entries for the routes and advertises the entries to PE 3. PE 3 can use those MAC address entries to forward traffic to CE 1 when the AC on PE 1 fails.

You must enable local FRR for EVPN VPLS before you execute this command.

# Enable the device to generate MAC address entries for received MAC/IP advertisement routes.

Parameters

single-active: Specifies the single-active mode.

all-active: Specifies the all-active mode.

Usage guidelines

This command is supported only by a multihomed EVPN VPWS, EVPN VPLS, EVPN VPWS over SRv6, or EVPN VPLS over SRv6 network. A multihomed EVPN VXLAN network supports only the all-active mode.

The redundant PEs at a dualhomed site each establish an EVPN PW or SRv6 PW to a remote PE. To use one PW as a backup of the other PW, use the single-active mode. To distribute traffic across the PWs for load sharing, use the all-active mode.

You can set the redundancy mode for a VSI LDP PW or VSI static PW only if you specify the dci or no-split-horizon keyword in executing the peer command for the PW.

PEs at a multihomed site send UMRs that carry the ESIs configured in VSI view. You can set the redundancy mode for an ES in VSI view.

As a best practice, set the same redundancy mode on the VSIs and their interfaces or UPWs that act as ACs or are configured with ACs on the redundant PEs at a multihomed site.

Make sure the interface, UPW, or VSI where you execute this command is assigned an ESI.

Parameters

detect-cycle detect-time: Sets the ARP mobility detection cycle in seconds, in the range of 60 to 900. The default value is 180 seconds.

detect-threshold move-times: Sets the ARP mobility suppression threshold, in the range of 3 to 10. The default is 5. This threshold is the number of ARP moves from the local site to remote sites.

suppression-time: Sets the ARP mobility suppression time. A suppressed ARP entry cannot move until the ARP mobility suppression time expires. If you do not set this parameter, the default setting permanent applies.

suppression-time: Specifies the ARP mobility suppression time in seconds, in the range of 120 to 3600 seconds.

permanent: Suppresses ARP moves permanently.

Usage guidelines

On an EVPN VXLAN or EVPN VPLS network, misconfiguration of IP addresses might cause two sites to contain the same IP address. In this condition, VTEPs or PEs at the two sites constantly synchronize and update EVPN ARP entries and determine that ARP mobility events occur. As a result, an inter-site loop might occur, and the bandwidth is occupied by ARP entry synchronization traffic. To eliminate loops and suppress those ARP mobility events, enable ARP mobility event suppression on the VTEPs or PEs.

The ARP mobility event suppression feature allows an IP address to move at most the specified number of times (ARP mobility suppression threshold) out of a site within an ARP mobility detection cycle. If the suppression threshold has been reached for an IP address within a detection cycle, the VTEP or PE at the site suppresses the subsequent move after the IP address moves back to the site. In addition, the VTEP or PE learns ARP information for the IP address but does not advertise the ARP information.

After you execute the undo evpn route arp-mobility suppression command or when the ARP mobility suppression time expires, a VTEP or PE acts as follows:

· Advertises ARP information immediately for the suppressed ARP entries that have not aged out.

· Relearns ARP information for the suppressed ARP entries that have aged out and advertises the ARP information.

ARP mobility event suppression takes effect only on an EVPN VXLAN network configured with distributed VXLAN IP gateways.

The ARP mobility event suppression setting configured in system view takes effect on all EVPN instances. The ARP mobility event suppression setting configured in EVPN instance view takes effect on all associated VSIs.

suppression-time: Specifies the MAC mobility suppression time in seconds, in the range of 120 to 3600 seconds.

permanent: Suppresses MAC moves permanently.

Usage guidelines

On an EVPN VXLAN or EVPN VPLS network, misconfiguration of MAC addresses might cause two sites to contain the same MAC address. In this condition, VTEPs or PEs at the two sites constantly synchronize and update EVPN MAC entries and determine that MAC mobility events occur. As a result, an inter-site loop might occur, and the bandwidth is occupied by MAC entry synchronization traffic. To eliminate loops and suppress those MAC mobility events, enable MAC mobility event suppression on the VTEPs or PEs.

The MAC mobility event suppression feature allows a MAC address to move at most the specified number of times (MAC mobility suppression threshold) out of a site within an MAC mobility detection cycle. If the suppression threshold has been reached for a MAC address within a detection cycle, the VTEP or PE at the site suppresses the subsequent move after the MAC address moves back to the site. In addition, the VTEP or PE learns the MAC address but does not advertise it.

After you execute the undo evpn route mac-mobility suppression command or when the MAC mobility suppression time expires, a VTEP or PE acts as follows:

· Advertises MAC address entries immediately for the suppressed MAC address entries that have not aged out.

· Relearns the MAC addresses for the suppressed MAC address entries that have aged out and advertises the MAC address entries.

suppression-time: Specifies the suppression time in seconds. The value range for this argument is 120 to 3600.

permanent: Suppresses ND moves permanently.

Usage guidelines

On an EVPN VXLAN network, misconfiguration of IP addresses might cause two sites to contain the same IP address. In this condition, VTEPs at the two sites constantly synchronize and update EVPN ND entries and determine that ND mobility events occur. As a result, an inter-site loop might occur, and the bandwidth is occupied by ND entry synchronization traffic. To eliminate loops and suppress those ND mobility events, enable ND mobility event suppression on the VTEPs. This feature allows an IP address to move a specified number of times (the ND mobility suppression threshold) from a site within an ND mobility detection cycle. If an IP address moves more than the ND mobility suppression threshold, the VTEP at the site will suppress the last ND move to the local site and will not advertise ND information for the IP address.

After you execute the undo evpn route nd-mobility suppression command or the suppression time expires, a VTEP acts as follows:

· Advertises ND information immediately for the suppressed ND entries that have not aged out.

· Relearns ND information for the suppressed ND entries that have aged out and advertises the ND information.

ND mobility event suppression takes effect only on the following networks:

· EVPN VXLAN network enabled with ND flood suppression.

Parameters

delay-time: Specifies a delay value in the range of 3 to 1200 seconds.

Usage guidelines

The advertisement delay timer for Ethernet auto-discovery routes helps reduce the traffic loss caused by a PE reboot at a multihomed EVPN VPLS network site.

At a multihomed EVPN VPLS network site, CE 1 is dualhomed to PE 1 and PE 2 through an aggregate link or smart trunk, and PE 3 is at a remote site. PE 1 forwards all traffic sent from CE 1 to the remote site, and PE 3 forwards the traffic that the remote site sends to CE 1 to both PE 1 and PE 2. When PE 1 reboots, it advertises Ethernet auto-discovery routes that carry next hop information to PE 3. If PE 3 has not received the MAC/IP advertisement routes advertised by PE 2 when receiving the Ethernet auto-discovery routes, it will forward traffic to both PE 1 and PE 2. In this situation, PE 1 does not have MAC address entries for CE 1 and drops the traffic.

To resolve this issue, set the advertisement delay timer for Ethernet auto-discovery routes on the CE-facing interface of PE 1. This timer allows PE 3 to receive the MAC/IP advertisement routes advertised by PE 2 before the Ethernet auto-discovery routes advertised by PE 1 and update its MAC address table timely.

Parameters

delay-time: Specifies a delay value in the range of 3 to 1200 seconds.

Usage guidelines

Use this command in combination with the evpn track peer command.

The evpn track peer command excludes unavailable edge devices from DF election at a multihomed site. After an edge device recovers from failure and brings up its CE-facing interface, it starts the advertisement delay timer for Ethernet segment routes and checks the status of the BGP peer specified in this command. If the BGP peer comes up before the timer expires, the edge device advertises Ethernet segment routes to the peer. If the BGP peer is still down when the timer expires, the edge device does not advertise Ethernet segment routes to the peer. The edge devices then perform DF election based on the Ethernet segment routes they have received.

Parameters

session-name: Specifies a static BFD session name, a case-sensitive string of 1 to 15 characters.

Usage guidelines

Use this command on a BDF for fast DF/BDF switchover.

At a multihomed site of an EVPN VPWS network, a BDF cannot take over the DF role immediately when an AC on a DF fails, and traffic loss will occur as a result. To resolve this issue, set up a static BFD session between the DF and BDF. You must configure the static BFD session to monitor the status of the local AC on the DF and enable the BDF to monitor the status of the session. When the AC on the DF fails, the static BFD session goes down, and the BDF can fast take over the DF role to reduce traffic loss.

To modify the static BFD session monitored on an interface, first use the undo evpn track bfd command to remove the existing static BFD session configuration.

Usage guidelines

This command helps reduce the traffic loss caused by AC failure at a multihomed EVPN VPLS, EVPN VPWS, EVPN VPLS over SRv6, or EVPN VPWS over SRv6 network site that uses single-active redundancy mode.

At a multihomed EVPN network site that uses single-active redundancy mode, CE 1 is dualhomed to PE 1 and PE 2 through a smart trunk. PE 1 is the primary PE, and PE 2 is the secondary PE. When the AC on PE 1 fails, PE 1 and PE 2 act as follows:

· PE 1 withdraws advertised Ethernet auto-discovery routes.

· PE 2 brings up its AC and advertises Ethernet auto-discovery routes to remote PEs.

The remote PEs switch traffic to the paths to PE 2 only after receiving the Ethernet auto-discovery routes advertised by PE 2, and traffic loss occurs during path switchover. To resolve this issue, enable VSIs or cross-connects to ignore the state of ACs on PE 2. This feature allows PE 2 to advertise Ethernet auto-discovery routes to remote PEs regardless of the state of ACs and speeds up path switchover when the AC on PE 1 fails.

On a VSI or cross-connect, VSI-specific or cross-connect-specific AC state ignore configuration takes precedence over global AC state ignore configuration.

Use the ignore-ac-state enable command together with the evpn multihoming re-originated mac command.

Examples

# Enable VSI vpna to ignore the state of ACs.

Predefined user roles

network-admin

Parameters

vxlan-id: Specifies a VXLAN ID in the range of 0 to 16777215.

Usage guidelines

On distributed EVPN gateways, you must configure L3 VXLAN IDs for the gateways to differentiate traffic of different VPN instances.

To forward Layer 3 traffic of a VPN instance, you must assign an L3 VXLAN ID to the VSI interface of the VPN instance. To forward Layer 3 traffic of the public network, you must assign the same L3 VXLAN ID to the public instance and the VSI interface of the public instance.

To modify the L3 VXLAN ID for the public instance, you must first delete the original L3 VXLAN ID.

If a VSI interface has been assigned an L3 VXLAN ID and a MAC address, you must also assign the same MAC address to the other VSI interfaces that are assigned L3 VXLAN IDs. That MAC address will be used as the router MAC address by the distributed EVPN gateway interfaces.

The L3 VXLAN ID specified by using this command cannot be the same as any VXLAN ID specified by using the mapping vni command.

Examples

# Configure the L3 VXLAN ID as 1000 for VSI-interface 100.

undo mac-address source-mac-check ac mac-address mask

Default

AC source MAC check is disabled.

Views

VSI view

Predefined user roles

network-admin

Parameters

mac-address mask: Specifies a MAC address and a MAC address mask in H-H-H format. You cannot specify a multicast or all-zero MAC address. The value range for the mask argument varies by device model. You must enter consecutive 1s in the MAC address mask. For example, enter ffff-ffff-ff00 for a 40-digit MAC address mask.

Usage guidelines

In an EVPN VPLS or EVPN VXLAN network, devices advertise local MAC addresses to remote sites through BGP EVPN routes. If the device erroneously learns a local MAC address identical to an advertised remote MAC address, it will refresh the related MAC address entry and fail to forward the traffic destined for the remote MAC address.

To prevent the device from learning incorrect local MAC address entries, enable AC source MAC check. This feature disables the device from learning the source MAC address of a packet received from an AC if the source MAC address is in the MAC address list for AC source MAC check.

If you repeat the mac-address source-mac-check command to specify different MAC addresses, all the specified MAC addresses are added for AC source MAC check. If you repeat the mac-address source-mac-check command to specify the same MAC address and different MAC address masks, the most recent configuration takes effect.

If you delete all MAC addresses for AC source MAC check, this feature is disabled.

To delete a MAC address for AC source MAC check, you must specify the correct MAC address and MAC address mask. To view the MAC addresses for AC source MAC check, execute the display this command in VSI view.

Parameters

vxlan-id: Specifies a remote VXLAN ID in the range of 0 to 16777215.

Usage guidelines

This command is supported only by EVPN instances that use VXLAN encapsulation.

The VXLAN mapping feature provides Layer 2 connectivity for a tenant subnet that uses different VXLAN IDs in multiple data centers.

VXLAN mapping includes the following types:

· Non-intermediate VXLAN mapping—When two data centers use different VXLAN IDs for a subnet, map the local VXLAN to the remote VXLAN on the ED of one data center. For example, for VXLAN 10 of data center 1 to communicate with VXLAN 20 of data center 2, map VXLAN 10 to VXLAN 20 on the ED of data center 1.

· Intermediate VXLAN mapping—When multiple data centers use different VXLAN IDs for a subnet, map the VXLANs to an intermediate VXLAN on all EDs. For example, data center 1 uses VXLAN 10, data center 2 uses VXLAN 20, and data center 3 uses VXLAN 30. To provide connectivity for the VXLANs, map them to intermediate VXLAN 500 on EDs of the data centers. You must use intermediate VXLAN mapping if more than two data centers use different VXLAN IDs. The intermediate VXLAN can be used only for VXLAN mapping, and it cannot be used for common VXLAN services.

You must create mapped remote VXLANs on the device, create an EVPN instance for each remote VXLAN, and configure RD and route target settings for the EVPN instances.

A mapped remote VXLAN ID cannot be an L3 VXLAN ID specified by using the l3-vni command.

Parameters

group-name: Specifies a peer group by its name, a case-sensitive string of 1 to 47 characters. The peer group must exist.

ipv4-address: Specifies a peer by its IPv4 address. The peer must exist.

mask-length: Specifies a mask length in the range of 0 to 32. You can use the ipv4-address and mask-length arguments together to specify a subnet. If you specify a subnet, this command specifies the maximum number of MAC/IP advertisement routes that can be received from all dynamic peers in the subnet.

ipv6-address: Specifies a peer by its IPv6 address. The peer must exist.

prefix-length: Specifies a prefix length in the range of 0 to 128. You can use the ipv6-address and prefix-length arguments together to specify a subnet. If you specify a subnet, this command specifies the maximum number of MAC/IP advertisement routes that can be received from all dynamic peers in the subnet.

route-number: Specifies the number of MAC/IP advertisement routes that can be received from the peer or peer group. The value range for this argument is 1 to 4294967295. The device will tear down the session to the peer or peer group if the following conditions exist:

· The alert-only, discard, and reconnect keywords are not specified.

· The number of MAC/IP advertisement routes received from the peer or peer group reaches the value of the route-number argument.

The device will not attempt to re-establish a session to a dynamic BGP peer until the device receives a connection request from the peer. For peers of other types, you can use the reset bgp command to re-establish sessions to them.

alert-only: Enables the device to generate a log message instead of tearing down the session to the peer or peer group when the set limit is reached. The device can continue receiving routes from the peer or peer group.

discard: Enables the device to retain the session to the peer or peer group, discard excess routes and generate a log message when the set limit is reached. After the number of MAC/IP advertisement routes received from the peer or peer group falls below the limit, the device can continue receiving routes from the peer or peer group. To restore the discarded routes, use the refresh bgp import command to request the peer or peer group to resend the routes.

reconnect reconnect-time: Specifies a delay for reconnecting to the peer or peer group after the set limit is reached. After this reconnection delay has elapsed, the device re-establishes a session to the peer or peer group. The value range for the reconnect-time argument is 1 to 65535 seconds. This reconnection delay does not take effect on dynamic BGP peers.

percentage-value: Specifies the threshold for the device to generate a log message, the ratio of the number of received MAC/IP advertisement routes to the set limit. The value range for this argument is 1 to 100, and the default is 75.

Usage guidelines

Use this command to protect the device from attacks of MAC/IP advertisement routes and enable the device to generate log messages for the MAC/IP advertisement routes received by the BGP EVPN address family.

In BGP EVPN address family view, you cannot execute both the peer macip-route-limit and peer route-limit commands for a peer or peer group.

Examples

# In BGP EVPN address family view, limit the number of MAC/IP advertisement routes received from the peer at 1.1.1.1 to 10000, and configure the device to disconnect from the peer if this limit is reached.

Parameters

group-name: Specifies a peer group by its name, a case-sensitive string of 1 to 47 characters. The peer group must exist.

ipv4-address: Specifies a peer by its IPv4 address. The peer must exist.

mask-length: Specifies a mask length in the range of 0 to 32. To specify a subnet, you must specify both the ipv4-address and mask-length arguments.

ip-prefix: Specifies IP prefix advertisement routes.

mac-ip: Specifies MAC/IP advertisement routes.

replace-rt: Replaces the L3 VXLAN ID, RD, and route targets of BGP EVPN routes with those of the matching local VPN instance. If you do not specify this keyword, only the L3 VXLAN ID and RD will be replaced.

Usage guidelines

In an EVPN-DCI network, use this command to hide the L3 VXLAN IDs of data centers or enable communication between data centers that use different L3 VXLAN IDs or route targets.

After you execute this command on an ED, the ED performs the following operations after receiving BGP EVPN routes from a VTEP or remote ED:

1. Matches the route targets of the routes with the import route targets of local VPN instances.

2. Replaces the L3 VXLAN ID, RD, and route targets of the routes with those of the matching local VPN instance.

3. Advertises the routes to a VTEP or remote ED.

After you execute this command, an ED advertises only reoriginated BGP EVPN routes. The original BGP EVPN routes are not advertised.

If the RD of a received BGP EVPN route is identical to the RD of the matching local VPN instance, an ED does not replace the L3 VXLAN ID and route targets of the route or reoriginate the route. As a result, the ED does not advertise the route. As a best practice, assign unique RDs to VPN instances on different EVPN gateways and EDs when you use this command.

If you do not specify the ip-prefix or mac-ip keyword, this command takes effect on IP prefix advertisement routes.

replace-rt: Replaces the encapsulation type, VXLAN ID, MPLS label, RD, and route targets of a MAC/IP advertisement route with those of the other EVPN instance bound to the local VSI that receives the route. If you do not specify this keyword, only the encapsulation type, VXLAN ID, MPLS label, and RD will be replaced.

Usage guidelines

To enable communication between an EVPN VXLAN network and an EVPN VPLS network, execute this command on the intermediate border devices that interconnect the networks. This command enables these networks to exchange MAC/IP advertisement routes.

For this command to take effect, first execute the evpn mac re-originated enable command.

Examples

# In BGP EVPN address family view, enable the device to reoriginate MAC/IP advertisement routes based on those received from the peer at 1.1.1.1. Configure the device to replace the encapsulation type, VXLAN ID, MPLS label, and RD when reoriginating MAC/IP advertisement routes.

ipv4-address: Specifies a peer by its IPv4 address. The peer must exist.

mask-length: Specifies a mask length in the range of 0 to 32. To specify a subnet, you must specify both the ipv4-address and mask-length arguments

Usage guidelines

This command enables an ED to use its router MAC address to replace the router MAC address of routes received from and advertised to a peer or peer group in the local data center. The router MAC replacement process is as follows:

· For routes received from the peer or peer group, the ED performs router MAC replacement and advertises the routes to remote EDs.

· For routes received from a remote data center, the ED performs router MAC replacement and advertises the routes to the peer or peer group.

Examples

# In BGP EVPN address family view, enable route router MAC replacement for peer 1.1.1.1.

Parameters

group-name: Specifies a peer group by its name, a case-sensitive string of 1 to 47 characters. The peer group must have been created.

ipv4-address: Specifies a peer by its IPv4 address. The peer must have been created.

mask-length: Specifies a mask length in the range of 0 to 32. You can use the ip-address and mask-length arguments together to specify a subnet.

ipv6-address: Specifies a peer by its IPv6 address. The peer must have been created.

prefix-length: Specifies a prefix length in the range of 0 to 128. You can use the ipv6-address and prefix-length arguments together to specify a subnet.

Usage guidelines

With EVPN ORF enabled, the device filters BGP EVPN routes advertised to all BGP EVPN peers with which the device has established both BGP EVPN sessions and BGP IPv4 RT-Filter sessions. The device performs route filtering based on the route targets in BGP IPv4 RT-Filter routes. If EVPN ORF is not enabled on a BGP EVPN peer, the BGP EVPN peer might advertise only some local route targets or even does not advertise local route targets. As a result, the device advertises only some BGP EVPN routes or even does not advertise BGP EVPN routes to the BGP EVPN peer.

For the device to advertise BGP EVPN routes to the EVPN ORF-incapable BGP EVPN peers that have established BGP IPv4 RT-Filter sessions with the device, disable EVPN ORF for those BGP EVPN peers. The device will skip route filtering when advertising BGP EVPN routes to those BGP EVPN peers.

Usage guidelines

You can use this command to detect connectivity of a PW to the remote PE when traffic loss or interruption occurs in an EVPN VPLS network. The process of a ping operation is as follows:

1. The PW source PE sends MPLS echo requests that contain the PW labels of the PW to the PW destination PE based on the destination MAC address and VSI you specify.

2. The PW destination PE looks up the routing table and responds to the PW source PE with MPLS echo replies.

3. The PW source PE outputs packet statistics and the test result based on whether and when it receives MPLS echo replies.

Examples

# Ping the remote VM with MAC address 2-2-2 in an EVPN VPLS network.

· 32-bit IP address:16-bit user-defined number. For example, 192.168.122.15:1.

· 32-bit AS number:16-bit user-defined number. For example, 65536:1. The AS number must be equal to or greater than 65536.

· 32-bit dotted AS number:16-bit user-defined number. For example, 10.1:1.

auto: Automatically generates an RD in the N:VXLAN ID format. The initial value of N is 1. If N:VXLAN ID is already in use, the system increases the value of N by 1 until the RD is available.

router-id: Automatically generates an RD based on the router ID in the Router ID:N format. The initial value of N is 1. If Router ID:N is already in use, the system increases the value of N by 1 until the RD is available. If you do not specify this keyword with the auto keyword, the system automatically generates an RD based on the VXLAN ID in the N:VXLAN ID format.

Usage guidelines

EVPN uses MP-BGP to advertise BGP EVPN routes for automatic VTEP or PE discovery, MAC reachability information advertisement, and host route advertisement. MP-BGP uses the RD to differentiate BGP EVPN routes of different EVPN instances.

To modify the RD, first execute the undo route-distinguisher command to remove the original RD.

Parameters

mac-mobility-suppression: Specifies the MAC mobility suppression notification.

Usage guidelines

If SNMP notifications are enabled for EVPN, a MAC mobility suppression notification is sent to SNMP module after the MAC mobility suppression threshold is reached. For SNMP notifications to be sent correctly, you must also configure SNMP on the device. For more information about SNMP configuration, see Network Management and Monitoring Configuration Guide.

If you do not specify any parameter, all EVPN notifications are enabled or disabled.

Parameters

xconnect-group group-name: Specifies a cross-connect group by its name, a case-sensitive string of 1 to 31 characters. The name cannot contain hyphens (-).

local-service-id: Specifies a local service ID in the range of 1 to 16777215.

remote-service-id: Specifies a remote service ID in the range of 1 to 16777215.

-a source-ip: Specifies the source IP address of MPLS echo requests. If you do not specify a source IP address, the MPLS LSR ID of the device is used as the source IP address of MPLS echo requests.

-exp exp-value: Specifies the EXP value of MPLS echo requests. The value range for the exp-value argument is 0 to 7, and the default value is 0.

-h ttl-value: Specifies the maximum TTL value in the MPLS echo requests. The value range for the ttl-value argument is 1 to 255, and the default is 255.

-r reply-mode: Specifies the reply mode used by the receiver to reply to MPLS echo requests. The value of the reply-mode argument is in the range of 1 to 4, and the default value is 2.

· 1—Do no reply.

· 2—Reply with UDP packets.

· 3—Reply with UDP packets that carry the Router Alert option.

· 4—Reply with VCCV packets.

ddmap: Encapsulates the Downstream Detailed Mapping (DDMAP) TLV in MPLS echo replies and MPLS echo requests. If you do not specify this keyword, Downstream Mapping TLV (DSMAP) will be encapsulated in these packets. The DDMAP TLV and DSMAP TLV carry the downstream information of the current node, including the next hop address and outgoing label. When you perform MPLS tracert operations, the device will verify the next hop address and outgoing label in the DDMAP TLV and DSMAP TLV. If both the address and label are correct, the device sends a normal MPLS echo reply to the ingress node. If the address or label is incorrect, the device sends an MPLS echo reply with an error code to the ingress node.

full-lsp-path: Displays the complete LSP path from the local PE to the destination PE. If you do not specify this keyword, the command displays only the rely sent by the egress node for the PW.

Usage guidelines

Use this command to locate failed nodes on the path for a PW that has traffic loss or interruption issues in an EVPN VPWS network.

To trace the route over a PW, make sure the PW uses a PW class whose VCCV control channel type has been configured by using the vccv cc command.

Examples

# Trace the route for the PW whose local service ID is 100 and remote service ID is 200 for cross-connect group xcga.

<Sysname> tracert evpn vpws xconnect-group xcga 100 200

Trace route to a remote PE through a PW with local service ID 100 and remote

service ID 200 in cross-connect group 4.

Parameters

vsi vsi-name: Specifies a VSI by its name, a case-sensitive string of 1 to 31 characters.

mac mac-address: Specifies a host attached to a remote PE by its MAC address in H-H-H format. Do not specify a broadcast MAC address, multicast MAC address, or all-zero MAC address.

-a source-ip: Specifies the source IP address of MPLS echo requests. If you do not specify a source IP address, the primary IP address of the traffic outgoing interface is used as the source IP address of MPLS echo requests.

-exp exp-value: Specifies the EXP value of MPLS echo requests. The value range for the exp-value argument is 0 to 7, and the default value is 0.

-h ttl-value: Specifies the maximum TTL value in the MPLS echo requests. The value range for the ttl-value argument is 1 to 255, and the default value is 255.

-r reply-mode: Specifies the reply mode used by the receiver to reply to MPLS echo requests. The value of the reply-mode argument can be 2 or 4, and the default value is 2. The value 2 represents forwarding the replies based on the IP forwarding table, and the value 4 represents forwarding the replies over the PWs of the VSI.

-rtos tos-value: Specifies the ToS value in the IP header of MPLS echo replies. The value range for the tos-value argument is 0 to 7, and the default value is 6.

Usage guidelines

Use this command to locate failed nodes on the path for a PW that has traffic loss or interruption issues in an EVPN VPLS network. The process of a tracert operation is as follows:

1. The PW source PE sends MPLS echo requests that contain the PW labels of the PW to the PW destination PE based on the destination MAC address and VSI you specify. The TTL in the IP header of the requests is set to 1.

2. The first hop on the path responds to the PW source PE with a TTL-expired ICMP error message.

3. The PW source PE sends MPLS echo requests with the TTL set to 2 if the PE receives the TTL-expired ICMP error message or has not received any packets within the timeout period.

4. The second hop responds with a TTL-expired ICMP error message.

5. This process continues until an MPLS echo request reaches the PW destination PE or the maximum TTL value is reached. If an MPLS echo request reaches the PW destination PE, the PW destination PE sends an MPLS echo reply to the PW source PE.

6. The PW source PE outputs packet statistics and the test result based on the received ICMP error messages and on whether an MPLS echo reply is received.

Examples

# In an EVPN VPLS network, trace the route for the PW whose remote PE is attached to a host with MAC address 1-1-1 in VSi vpna.

<Sysname> tracert evpn vsi vpna mac 1-1-1

Parameters

tunnel-policy-name: Specifies a tunnel policy by its name, a case-sensitive string of 1 to 126 characters.

Usage guidelines

This command is supported only by EVPN instances that use MPLS encapsulation.

The PWs of the VSI EVPN instance use the specified tunnel policy to select public tunnels.

In EVPN instance view, the specified tunnel policy takes effect on all VSIs associated with the EVPN instance.

If you do not specify a tunnel policy or specify a nonexistent tunnel policy, the default tunnel policy applies. The default tunnel policy selects only one public tunnel for a PW in this order: LSP tunnel, GRE tunnel, CRLSP tunnel, and SRLSP tunnel.

If you execute this command multiple times, the most recent configuration takes effect.

Parameters

receive: Enables UMR reception.

send: Enables UMR advertisement.

detail-suppressed: Suppresses detail routes. If you do not specify this keyword, detail routes are advertised with UMR routes simultaneously.

Usage guidelines

In an EVPN VXLAN, EVPN VPLS, or EVPN VPLS over SRv6 network, you can configure edge devices such as VTEPs and PEs to advertise and receive UMRs. UMRs refer to MAC/IP advertisement routes for MAC address 0-0-0.

With UMR reception enabled, an edge device adds a MAC address entry for MAC address 0-0-0 to the MAC address table of the related VSI after receiving a UMR route. That MAC address entry is a default MAC address entry. When the edge device receives a packet from an AC of the VSI, it looks up the MAC address table for a matching entry. If no match is found for the destination MAC address, the edge device forwards the packet based on the default MAC address entry.

You can use UMRs for the following purposes:

· To reduce the MAC address table size on edge devices and the number of MAC/IP advertisement routes when network sites accommodate a large number of hosts.

· To avoid traffic loss when unknown unicast floods are suppressed. When unknown unicast floods are suppressed on the local edge device, enable remote edge devices to advertise UMRs for the local edge device to forward unknown unicast packets to the remote sites.

After an edge device receives a UMR, it forwards all unknown unicast packets to the remote edge device that advertises the UMR. If the UMR does not point to the remote site that accommodates the destination of the unknown unicast packets, forwarding failure will occur. To ensure correct traffic forwarding, enable UMR advertisement or reception with caution.

To modify UMR advertisement and reception settings, first use the undo unknown-mac-route command to disable UMR advertisement and reception.

# Enable UMR advertisement and reception in EVPN instance view of VSI vpna.

Views

BGP EVPN address family view

Predefined user roles

network-admin

Usage guidelines

Application scenarios

Enable EVPN ORF to reduce the BGP EVPN routes advertised by BGP EVPN peers in a large EVPN network.

By default, the device advertises BGP EVPN routes to a peer even if no EVPN instance on the peer matches the route targets in the BGP EVPN routes. To reduce resource consumption and save bandwidth, enable EVPN ORF for the device to advertise only BGP EVPN routes of interest to each BGP EVPN peer.

Operating mechanism

To use EVPN ORF, you must also configure BGP IPv4 RT-Filter route exchange. With EVPN ORF enabled, the device filters all BGP EVPN routes advertised to the BGP EVPN peers with which the device has established BGP EVPN sessions and BGP IPv4 RT-Filter sessions as follows:

· If the route targets in a BGP EVPN route match a received BGP IPv4 RT-Filter route, the device advertises the BGP EVPN route to the peer that advertises the BGP IPv4 RT-Filter route.

· If the route targets in a BGP EVPN route do not match any received BGP IPv4 RT-Filter route, the device does not advertise the BGP EVPN route.

With EVPN ORF disabled, the device advertises the route targets configured in public instance IPv4 address family view and VPN instance address family view through BGP IPv4 RT-Filter routes. After you enable EVPN ORF, the device also advertises the following route targets through BGP IPv4 RT-Filter routes:

· Import targets configured in VPN instance EVPN view and public instance EVPN view.

· Import targets configured for EVPN in VPN instance IPv4 address family view.

· Import targets configured in VSI EVPN instance view.

· ES-Import route targets automatically generated based on the ESIs of interfaces, UPWs, and VSIs.

All the route targets carried by BGP IPv4 RT-Filter routes are used for filtering of BGP EVPN routes.

Restrictions and guidelines

To use EVPN ORF, enable it on both ends of a BGP EVPN session. With EVPN ORF enabled, the device does not filter the BGP EVPN routes advertised to peers with which the device has established only BGP EVPN sessions. The device advertises all BGP EVPN routes to those peers.

BGP IPv4 RT-Filter routes do not carry the route targets configured for IPv6 VPN. Therefore, some BGP EVPN routes carrying IPv6 addresses cannot be advertised. For example, if import target 8:8 is configured for EVPN in IPv6 address family view of VPN instance vpn1, BGP IPv4 RT-Filter routes do not carry this route target. As a result, the device cannot receive the IPv6 BGP EVPN routes carrying export target 8:8. To resolve this issue, configure identical route targets for IPv6 VPN and IPv4 VPN.

With EVPN ORF enabled, the device filters BGP EVPN routes advertised to all BGP EVPN peers with which the device has established both BGP EVPN sessions and BGP IPv4 RT-Filter sessions. If EVPN ORF is not enabled on a BGP EVPN peer, the BGP EVPN peer might advertise only some local route targets or even does not advertise local route targets. As a result, the device advertises only some BGP EVPN routes or even does not advertise BGP EVPN routes to the BGP EVPN peer. For the device to advertise BGP EVPN routes to the EVPN ORF-incapable BGP EVPN peers that have established BGP IPv4 RT-Filter sessions with the device, disable EVPN ORF for those BGP EVPN peers by using the peer vpn-orf ignore command. The device will skip route filtering when advertising BGP EVPN routes to those BGP EVPN peers.

Follow these guidelines when you use the vpn-orf enable and peer capability-advertise orf prefix-list commands in BGP EVPN address family view:

· The peer capability-advertise orf prefix-list command enables BGP EVPN route filtering based on the prefix list. The vpn-orf enable command enables BGP EVPN route filtering based on route targets. These commands are independent of each other.

· The peer capability-advertise orf prefix-list command takes effect on MAC/IP advertisement routes and IP prefix advertisement routes. The vpn-orf enable command takes effect on all BGP EVPN routes.

Parameters

vpn-target&<1-8>: Specifies a space-separated list of up to eight route targets. Each route target is a string of 3 to 21 characters in one of the following formats:

· 16-bit AS number:32-bit user-defined number. For example, 101:3.

· 32-bit IP address:16-bit user-defined number. For example, 192.168.122.15:1.

· 32-bit AS number:16-bit user-defined number. For example, 65536:1. The AS number must be equal to or greater than 65536.

· 32-bit dotted AS number:16-bit user-defined number. For example, 10.1:1.

auto: Automatically generates a route target in the format of BGP AS number:VXLAN ID.

both: Uses the specified route targets as both import and export targets. If you do not specify the both, export-extcommunity, or import-extcommunity keyword, the both keyword applies.

export-extcommunity: Uses the specified route targets as export targets.

import-extcommunity: Uses the specified route targets as import targets.

all: Specifies all route targets.

Usage guidelines

EVPN uses MP-BGP to advertise BGP EVPN routes for automatic VTEP or PE discovery, MAC reachability information advertisement, and host route advertisement. MP-BGP uses route targets to control the advertisement and acceptance of BGP EVPN routes.

A VTEP or PE sets the export targets for BGP EVPN routes before advertising the routes to remote VTEPs or PEs. The VTEP or PE checks the export targets of BGP EVPN routes from remote VTEPs or PEs and imports only BGP EVPN routes of which the export targets match the local import targets.

If you execute this command multiple times, all configured route targets take effect.
