track track-entry-number&<1-15>: Specifies a space-separated list of up to 15 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.

Usage guidelines

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

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.

# Map GigabitEthernet 1/0/1 to cross-connect aaa in cross-connect group vpna.

[Sysname] xconnect-group vpna

[Sysname-xcg-vpna] connection aaa

Usage guidelines

ARP request proxy allows a VSI interface to send an ARP request sourced from itself when the VTEP forwards an ARP request. This feature helps resolve certain communication issues.

In an EVPN VXLAN network, VM 1 and VM 2 are attached to VTEP 1 and VTEP 2, respectively, and the VMs are in the same subnet. The gateway interfaces of VM 1 and VM 2 are VSI-interface 1 on VTEP 1 and VSI-interface 2 on VTEP 2, respectively. The following conditions exist on the VTEPs:

· The VTEPs have established BGP EVPN neighbor relationships.

· EVPN is disabled from learning MAC addresses from ARP information.

· MAC address advertisement is disabled, and advertised MAC addresses are withdrawn.

· Remote-MAC address learning is disabled.

· Local proxy ARP is enabled on the VSI interfaces.

· The VSI interfaces use different IP addresses and MAC addresses.

In this network, when VM 1 attempts to communicate with VM 2, the following procedure occurs:

1. VM 1 sends an ARP request.

2. VTEP 1 learns the MAC address of VM 1 from the ARP request, replies to VM 1 on behalf of VM 2, and sends an ARP request to obtain the MAC address of VM 2.

3. VTEP 2 forwards the ARP request, and VM 2 replies to VTEP 1.

4. VTEP 2 forwards the ARP reply sent by VM 2 without learning the MAC address of VM 2 because EVPN is disabled from learning MAC addresses from ARP information.

5. VTEP 1 does not learn the MAC address of VM 2 because remote-MAC address learning is disabled.

As a result, VM 1 fails to communicate with VM 2.

For VM 1 to communicate with VM 2, enable ARP request proxy on VSI-interface 2 of VTEP 2. When receiving the ARP request sent by VTEP 1, VTEP 2 forwards it and sends an ARP request sourced from VSI-interface 2 simultaneously, and VM 2 replies to both ARP requests. Then, VTEP 2 learns the MAC address of VM 2 from the ARP reply destined from VSI-interface 2 and advertises the MAC address to VTEP 1 through BGP EVPN routes. In this way, VTEP 1 obtains the MAC address of VM 2, and VM 1 and VM 2 can communicate.

Examples

# Enable ARP request proxy on VSI-interface 100.

Usage guidelines

In an EVPN VXLAN network with distributed gateways, you can disable ARP information advertisement for a VXLAN network to save resources if all its user terminals use the same EVPN gateway device. The EVPN instance of the VXLAN network 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.

Predefined user roles

network-admin

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, 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 redundancy mode (if configured) of the main interface. In this scenario, the redundancy mode configured on the subinterface does not take effect.

You can assign an ESI to a VSI LDP PW or VSI static PW only if you do not specify the no-split-horizon or dci keyword when executing the peer command for the PW.

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

Predefined user roles

network-admin

Usage guidelines

Application scenarios

At a multihomed EVPN network site, all PEs or VTEPs attached to an ES participate in DF election by default, regardless of their AC states. If the AC on the PE or VTEP elected as the DF is down, traffic forwarding will fail. You can configure AC state-based DF election to resolve this issue.

Operating mechanism

After you configure AC state-based DF election, a PE or VTEP participates in DF election only when the AC on the PE or VTEP is up. A PE or VTEP determines that the AC on the remote PE or VTEP is up only when it receives AD per ES and AD per EVI routes from the remote PE or VTEP.

Restrictions and guidelines

AC state-based DF election takes effect only after you enable this feature on all PEs or VTEPs attached to an ES.

Examples

# Enable AC state-based DF election.

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.

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.

tunnel-policy tunnel-policy-name: Specifies a tunnel policy by its name, a case-sensitive string of 1 to 19 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

Usage guidelines

If a distributed EVPN gateway has downstream VTEPs attached, the gateway advertises ARP information for gateway interfaces through IP prefix advertisement routes. Because the VTEPs do not have gateway configuration, they cannot learn the ARP information for the gateway interfaces or forward traffic to the gateway. For the VTEPs to learn ARP information for the gateway interfaces, enable the distributed EVPN gateway to advertise ARP information for the gateway interfaces through MAC/IP advertisement routes.

Examples

# Enable the device to advertise ARP information for the distributed EVPN gateway interfaces through MAC/IP advertisement routes.

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 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.

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

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 at the site suppresses the subsequent move after the IP address moves back to the site. In addition, the VTEP 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 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.

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

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

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

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 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.

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.

Usage guidelines

On an EVPN VXLAN network deployed with a centralized EVPN gateway, VM 1 and VM 2 belong to the same VXLAN in subnet 10.1.1.0/24. The gateway interface is VSI-interface 1 and the gateway is connected to external Layer 3 network 10.1.2.0/24. The VTEP to which VM 2 is attached is configured with ARP or ND flood suppression. The IP address of VM 2 is mistakenly configured as an IP address in subnet 10.1.2.0/24 (for example, 10.1.2.2). In this situation, the VTEP connected to VM 2 advertises MAC/IP advertisement routes that contain ARP or ND information to the gateway. The IP address and MAC address in the routes are the IP address and MAC address of VM 2, respectively. The gateway learns the ARP or ND information and issues the information to the forwarding table. When VM 1 visits 10.1.2.2 in the external network, the gateway will forward the traffic to VM 2. As a result, VM 1 cannot visit 10.1.2.2.

To resolve the above issue, perform this task on the VSI interface to disable the VSI interface from learning ARP or ND information across subnets from MAC/IP advertisement routes.

Examples

# Disable a VSI-interface 1 from learning ARP or ND information that does not belong to its subnet from MAC/IP advertisement routes.

evpn timer es-delay

Use evpn timer es-delay to set the advertisement delay timer for Ethernet segment routes.

Use undo evpn timer es-delay to delete the advertisement delay setting for Ethernet segment routes.

Syntax

evpn timer es-delay delay-time

undo evpn timer es-delay

Default

Advertisement of Ethernet segment routes is not delayed.

Views

Interface view

Predefined user roles

network-admin

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.

Examples

# On GigabitEthernet 1/0/1, set the advertisement delay timer for Ethernet segment routes to 300 seconds.

undo evpn timer es-recovery

Default

ES route advertisement delay is disabled when preference-based DF election is used.

Views

Interface view

Predefined user roles

network-admin

Parameters

recovery-time: Sets the ES route advertisement delay in the range of 3 to 1200 seconds.

Usage guidelines

When the DF restarts or the process restarts and a new DF is elected, the original DF will immediately advertise ES routes after the restart to become the DF again. However, access-side connections restore slowly and packet loss might occur after DF switchover. To resolve this issue, set the ES route advertisement delay.

As a best practice, configure this feature when the all-active redundancy mode is used. Do not configure this feature when the single-active redundancy mode is used.

Examples

# Set the ES route advertisement delay to 300 seconds.

Parameters

peer-ipv4-address: Specifies a VTEP or PE by its IPv4 address.

peer-ipv6-address: Specifies a VTEP or PE by its IPv6 address.

Usage guidelines

Use this command on the CE-facing interfaces of the edge devices multihomed to a site to prevent device reboots from causing inter-site forwarding failure.

This 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.

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.

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. To specify a subnet, you must specify both the ipv6-address and prefix-length arguments.

imet: Specifies IMET routes.

ip-prefix: Specifies IP prefix advertisement routes.

mac-ip: Specifies MAC/IP advertisement routes.

s-pmsi: Specifies S-PMSI routes.

smet: Specifies SMET routes.

replace-rt: Performs the following actions on IP prefix advertisement routes that match the route targets of a local VPN instance:

· Replaces the L3 VXLAN ID, RD, and route targets of the IP prefix advertisement routes with those of the matching local VPN instance.

· Adds MPLS labels or SRv6 SIDs to the routes, or requests SRv6 SIDs for the routes from the matching local VPN instance.

If you do not specify this keyword, only the L3 VXLAN ID and RD will be replaced, MPLS labels or SRv6 SIDs will be added, or SRv6 SIDs will be requested for the routes from the matching local VPN instance.

replace-sid: Deletes SRv6 SIDs from the received BGP EVPN routes that match the route targets of a local VPN instance, and requests SRv6 SIDs for the routes from the matching local VPN instance. If you do not specify this keyword, the SRv6 SIDs of received BGP EVPN routes will not be modified.

Usage guidelines

Application scenarios and operating mechanism for EVPN

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.

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 and RD of the routes with those of the matching local VPN instance.

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

Application scenarios and operating mechanism for SRv6

In a network with inter-AS SRv6 VPN deployed in multiple ASs, you can specify the replace-sid keyword to disable inter-AS advertisement of locator network routes for security purposes. SRv6 forwarding path setup between PEs of different ASs will not be affected.

Restrictions and guidelines

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 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 a route type, this command applies to IP prefix advertisement routes.

# Replace the L3 VXLAN ID and RD of the BGP EVPN routes received from peer 1.1.1.1.

Usage guidelines

When route target filtering is enabled for BGP EVPN routes, the EVPN routing table accepts only BGP EVPN routes of which the export route targets match the local import route targets. If the device must save all BGP EVPN routes, use the undo policy vpn-target command to disable route target filtering for BGP EVPN routes.

Examples

# Disable route target filtering for BGP EVPN routes.

Parameters

class-name: Specifies a PW class by its name, a case-sensitive string of 1 to 19 characters.

Usage guidelines

This command is supported whether a VSI EVPN instance uses MPLS encapsulation or SRv6 encapsulation.

The specified PW class will be used to establish all PWs on the VSI EVPN instance.

In EVPN instance view, the specified PW class takes effect on all VSIs associated with the EVPN instance.

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

reset evpn route arp-mobility suppression

Use reset evpn route arp-mobility suppression to cancel ARP mobility event suppression.

Syntax

reset evpn route arp-mobility suppression [ public-instance | vpn-instance vpn-instance-name [ ip ip-address ] ]

Views

User view

Predefined user roles

network-admin

Parameters

public-instance: Specifies the public instance.

vpn-instance vpn-instance-name: Specifies an MPLS L3VPN instance by its name, a case-sensitive string of 1 to 31 characters.

ip ip-address: Specifies an IPv4 address in dotted decimal notation. If you do not specify an IPv4 address, this command cancels the suppression done on all ARP entries of the public instance or specified MPLS L3VPN instance.

Usage guidelines

Use this command to cancel the ARP mobility event suppression done on IPv4 addresses. After you cancel suppression for an IPv4 address, the IPv4 address can move between sites, and the device advertises ARP information for the IPv4 address. The device still suppresses the IPv4 address if the suppression criteria are met.

If you do not specify the public instance or an MPLS L3VPN instance, this command cancels ARP mobility event suppression for the public instance and all MPLS L3VPN instances.

Examples

# Cancel the ARP mobility event suppression done on 1.1.1.1 of VPN instance vpna.

<Sysname> reset evpn route arp-mobility suppression vpn-instance vpna ip 1.1.1.1

Views

User view

Predefined user roles

network-admin

Parameters

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

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

vsi vsi-name: Specifies a VSI by its name, a case-sensitive string of 1 to 31 characters. If you do not specify this option, the command cancels suppression on MAC addresses for all VSIs.

mac mac-address: Specifies a MAC address in the format of H-H-H. You can omit the consecutive zeros at the beginning of each segment. For example, you can enter f-e2-1 for 000f-00e2-0001. If you do not specify a MAC address, this command cancels suppression all MAC addresses of the specified VSI.

Usage guidelines

This command is a one-time command.

This command allows the device to advertise suppressed MAC addresses of VSIs for one time. The device will continue suppressing MAC mobility events for the MAC addresses after you execute this command.

If you do not specify any parameters, this command advertises all suppressed MAC addresses.

Examples

# Cancel the MAC mobility event suppression done on 1-1-1 of VSI vpna.

<Sysname> reset evpn route mac-mobility suppression vsi vpna mac 1-1-1

Views

User view

Predefined user roles

network-admin

Parameters

public-instance: Specifies the public instance.

vpn-instance vpn-instance-name: Specifies an MPLS L3VPN instance by its name, a case-sensitive string of 1 to 31 characters.

ipv6 ipv6-address: Specifies an IPv6 address. If you do not specify an IPv6 address, this command cancels suppression on all ND entries of the public instance or specified MPLS L3VPN instance.

Usage guidelines

Use this command to cancel the ND mobility event suppression done on IPv6 addresses. After you cancel suppression for an IPv6 address, the IPv6 address can move between sites, and the device advertises ND information for the IPv6 address. The device still suppresses the IPv6 address if the suppression criteria are met.

If you do not specify the public instance or an MPLS L3VPN instance, this command cancels ND mobility event suppression for the public instance and all MPLS L3VPN instances.

Examples

# Cancel the ND mobility event suppression done on 1::1 of VPN instance vpna.

<Sysname> reset evpn route nd-mobility suppression vpn-instance vpna ipv6 1::1

Parameters

route-distinguisher: Specifies an RD, a string of 3 to 21 characters. The RD cannot be all zeros and can use 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.

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.

Usage guidelines

EVPN uses MP-BGP to advertise BGP EVPN routes for automatic VTEP 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.

Examples

# Configure 22:1 as the RD of an EVPN instance.

Default

SNMP notifications are disabled for EVPN.

Predefined user roles

network-admin

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.

Examples

# Enable SNMP notifications for EVPN.

Parameters

tunnel-policy-name: Specifies a tunnel policy by its name, a case-sensitive string of 1 to 19 characters.

Usage guidelines

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.

Examples

# Specify tunnel policy policy1 for the EVPN instance on VSI aa.

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.

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 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 sets the export targets for BGP EVPN routes before advertising the routes to remote VTEPs. The VTEP checks the export targets of BGP EVPN routes from remote VTEPs 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.

Examples

# Configure import route targets 10:1, 100:1, and 1000:1 for an EVPN instance.
