Usage guidelines

This command enables the device to advertise BGP EVPN routes to the local site after the device adds the routes to the routing table of a VPN instance. The BGP EVPN routes here are IP prefix advertisement routes and MAC/IP advertisement routes that contain ARP or ND information.

Examples

# Enable BGP EVPN route advertisement to the local site for VPN instance vpn1.

<Sysname> system-view

[Sysname] bgp 100

[Sysname-bgp-default] ip vpn-instance vpn1

Table 3 Reason why a route is not preferred

Reason	Description
preferred-value	Routes with larger preferred values exist.
local-preference	Routes with larger local preference values exist.
local-origin-route	There are routes whose local-origin-route attribute has a higher priority. BGP selects the optimal route from local routes in this order: route generated by the network command, route redistributed by the import-route command, and summary route.
as-path	Routes with smaller AS_PATH attribute values exist.
origin	There are routes whose origin has a higher priority. The route origins are IGP, EGP, and INCOMPLETE in descending order of priority.
med	Routes with smaller MED values exist.
remote-route	There are routes whose remote-route attribute has a higher priority. BGP selects the optimal route from remote routes in this order: · Route learned from an EBGP peer. · Route learned from a confederation EBGP peer. · Route learned from a confederation IBGP peer. · Route learned from an IBGP peer.
igp-cost	Routes with smaller IGP metrics exist.
relydepth	Routes with smaller recursion depth values exist.
rfc5004	A route received from an EBGP peer is the current optimal route. BGP does not change the optimal route when it receives routes from other EBGP peers.
router-id	Routes with smaller router IDs exist. If one of the routes is advertised by a route reflector, BGP compares the ORIGINATOR_ID of the route with the router IDs of other routes. Then, BGP selects the route with the smallest ID as the optimal route.
cluster-list	Routes with smaller CLUSTER_LIST attribute values exist.
peer-address	Routes advertised by peers with lower IP addresses exist.
redist-route	Routes of the current VPN instance exist.
rpki	Routes with higher RPKI validation state preferences exist.
received	Earlier learned routes exist.
evpn-macip-mobile	There are EVPN MAC/IP advertisement routes carrying the MAC mobility extended community attribute.
evpn-macip-mobile-static	There are EVPN MAC/IP advertisement routes whose static flag in the MAC mobility extended community attribute is set.
evpn-macip-mobile-seq	There are EVPN MAC/IP advertisement routes carrying a larger sequence number in the MAC mobility extended community attribute.
evpn-macip-mobile-routerid	There are EVPN MAC/IP advertisement routes carrying a smaller router ID in the MAC mobility extended community attribute.

esi

Use esi to assign an ESI to an interface.

Use undo esi to restore the default.

Syntax

esi esi-id

undo esi

Default

No ESI is assigned to an interface.

Views

Interface view

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 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 redundancy mode takes precedence over those configured on the main interface.

· 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.

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

Examples

# Assign ESI 0000.0001.0002.0003.0004 to HundredGigE 1/0/1.

<Sysname> system-view

[Sysname] interface hundredgige 1/0/1

[Sysname-HundredGigE1/0/1] esi 0000.0001.0002.0003.0004

esi type-1

Use esi type-1 to configure an interface to automatically generate a type-1 ESI.

Use undo esi type-1 to restore the default.

Syntax

esi type-1 [ pe ]

undo esi type-1

Default

An interface does not automatically generate a type-1 ESI.

Views

Predefined user roles

network-admin

Parameters

pe: Indicates that the LACP parameters used for automatically generating an ESI are derived from the PE device. If this keyword is not specified, the LACP parameters used for automatically generating an ESI are derived from the CE device.

Usage guidelines

An ESI uniquely identifies an ES. The links on interfaces with the same ESI belong to the same ES. Traffic of the ES can be distributed among the links for load sharing. With this feature configured, the device will automatically generate an ESI by using LACP-related parameters, and you do not need to manually assign an ESI.

To have this feature take effect, you must first enable LACP .

On the same interface, this command, the esi command, and the esi type-3 command are mutually exclusive.

Parameters

system-mac mac-address: Specifies a system MAC address for an interface, in the format of H-H-H. Multicast, all-zero, and all-F MAC addresses are not supported.

local-discriminator local-discriminator: Specifies a local discriminator for an interface. A local discriminator must be a number in the range of 1 to 16777215.

Usage guidelines

An ESI uniquely identifies an ES. The links on interfaces with the same ESI belong to the same ES. Traffic of the ES can be distributed among the links for load sharing. With this feature configured, the device will automatically generate an ESI for an interface by using the system MAC address and local discriminator of the interface, and you do not need to manually assign an ESI.

On the same interface, this command, the esi command, and the esi type-1 command are mutually exclusive.

Examples

# Configure an interface to automatically generate a type-3 ESI, with the system MAC address as 0-0-1 and the local discriminator as 100.

Use undo evpn df-election ac-influence enable to disable AC state-based DF election.

Syntax

undo evpn df-election ac-influence enable

Default

AC state-based DF election is disabled.

Views

System view

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.

<Sysname> system-view

[Sysname] evpn df-election ac-influence enable

evpn df-election algorithm (interface view)

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.

Examples

# Configure HundredGigE 1/0/1 to use the preference-based algorithm for DF election.

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.

evpn m-lag local mac-ip

Use evpn m-lag local mac-ip to allow only MAC/IP advertisement routes to carry the local VTEP address.

Use undo m-lag local mac-ip to restore the default.

Syntax

evpn m-lag local mac-ip

undo evpn m-lag local mac-ip

Default

IMET routes, MAC/IP advertisement routes, and IP prefix advertisement routes carry the local VTEP address.

Views

System view

Predefined user roles

network-admin

Usage guidelines

If you specify the local VTEP address for EVPN M-LAG, the device advertises the following BGP EVPN routes.

· IMET route in which the originator IP address is the local VTEP address.

· IP prefix advertisement route in which the next hop is the local VTEP address.

· MAC/IP advertisement route in which the next hop is the local VTEP address. This route is advertised for each MAC address entry or ARP entry learned on a local interface attached to a singlehomed peer device.

The device also advertises BGP EVPN routes that carry the virtual VTEP address of the M-LAG system. As a result, a peer VTEP sets up the following VXLAN tunnels with the device:

· A VXLAN tunnel sourced from the IP address of the peer VTEP and destined for the local VTEP address of the device. This tunnel is used to forward broadcast, unknown-unicast, and multicast (BUM) traffic and known unicast traffic for which the outgoing interface is an AC-attached interface facing a singlehomed device.

· A VXLAN tunnel sourced from the IP address of the peer VTEP and destined for the virtual VTEP address. This tunnel is used to forward BUM traffic and known unicast traffic for which the outgoing interface is an M-LAG interface.

If no peer device is singlehomed to an AC-attached interface of the M-LAG system, the VXLAN tunnel set up with the local VTEP address does not forward service traffic. To save tunnel resources, allow only MAC/IP advertisement routes to carry the local VTEP address. Then, the IMET routes and IP prefix advertisement routes advertised by the device will not carry the local VTEP address. If the device does not learn a MAC address entry or ARP entry on a local interface attached to a singlehomed peer device, it will not advertise a MAC/IP advertisement route in which the next hop is the local VTEP address. As a result, a peer VTEP will not set up a VXLAN tunnel with the local VTEP address.

Parameters

external-preference: Sets the preference of EBGP routes learned from EBGP peers to a value in the range of 1 to 255.

internal-preference: Sets the preference of IBGP routes learned from IBGP peers to a value in the range of 1 to 255.

route-policy-name: Specifies a routing policy by its name, a case-sensitive string of 1 to 63 characters. The preference of routes matching the routing policy will be set based on the routing policy. Routes that do not match the routing policy will use the default preference.

Usage guidelines

Application scenarios

Different routing protocols, direct routes, and static routes might discover different routes for the same destination in the IP routing table, but not all of these routes are optimal. To determine the optimal route, each routing protocol, direct route, and static route is assigned a preference, and the route discovered by the routing protocol with higher preference will become the optimal route.

Set the preference of MAC/IP advertisement routes redistributed to the BGP-VPN unicast address families for the routes to become the optimal routes in the IP routing table of a VPN instance.

Restrictions and guidelines

To use a routing policy for preference configuration, first use the apply preference command to set the preference of matching routes for the routing policy. If you do not set the preference of matching routes, the matching routes will use the default preference.

Examples

# In BGP-VPN IPv4 unicast address family view, set the preference to 20 for the MAC/IP advertisement routes learned from EBGP and IBGP peers.

Usage guidelines

Do not use this command on VTEPs at a multihomed EVPN VXLAN site if EVPN forwards multicast traffic based on SMET, IGMP join sync, and IGMP leave sync routes. Violation of this restriction might cause multicast forwarding errors.

EVPN multihoming routes include Ethernet auto-discovery routes and Ethernet segment routes.

In a multihomed EVPN network, execute this command on a redundant VTEP or PE before you reboot it. This operation allows other VTEPs or PEs to refresh their EVPN routing table to prevent traffic interruption caused by the reboot.

Parameters

delay-value: Specifies the DF election delay, in the range of 1 to 1200 seconds.

Usage guidelines

DF election delay defines the minimum interval allowed between two DF elections.

The DF election can be triggered by site-facing interface status changes, redundant VTEP or PE membership changes, and interface ESI changes. To prevent frequent DF elections from degrading network performance, set the DF election delay.

To fast elect a DF and avoid traffic interruption upon DF failure, set the DF election delay to 0 seconds.

evpn multihoming vxlan-frr local

undo evpn multihoming vxlan-frr local

Default

Views

System view

Predefined user roles

network-admin

Usage guidelines

Local FRR enables two VTEPs at a multihomed EVPN VXLAN network site to set up a bypass 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 VXLAN 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.

# Enable local FRR globally for EVPN VXLAN.

undo evpn route mac-mobility suppression

Default

MAC mobility event suppression is disabled.

Views

System view

Predefined user roles

network-admin

Parameters

detect-cycle detect-time: Specifies the MAC mobility detection cycle in seconds. The value range for the detect-time argument is 60 to 900, and the default is 180.

detect-threshold move-times: Specifies the MAC mobility suppression threshold, which is the number of MAC moves from the local site to a remote site. The value range for the move-times argument is 3 to 10, and the default is 5.

suppression-time: Specifies the length of time that a MAC address entry is suppressed. After the suppression time expires, the MAC address entry can move again. The default suppression time is permanent.

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

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. This feature allows a MAC address to move a specified number of times (the MAC mobility suppression threshold) from a site within a MAC mobility detection cycle. If a MAC address moves more than the MAC mobility suppression threshold, the VTEP or PE at the site will suppress the last MAC move to the local site and will not advertise information about the MAC address.

After you execute the undo evpn route mac-mobility suppression command or the 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.

Examples

# Enable MAC mobility event suppression.

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.

Syntax

ipv6 nd proxy-send enable

Default

ND request proxy is disabled on VSI interfaces.

Views

VSI interface view

Predefined user roles

network-admin

Usage guidelines

ND request proxy allows a VSI interface to send an ND request sourced from itself when the VTEP forwards an ND 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 ND information.

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

· Remote-MAC address learning is disabled.

· Local proxy ND 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 process occurs:

1. VM 1 sends an NS packet.

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

3. VTEP 2 forwards the NS packet, and VM 2 replies to VTEP 1.

4. VTEP 2 forwards the NA packet sent by VM 2 without learning the MAC address of VM 2 because EVPN is disabled from learning MAC addresses from ND 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 NS packet proxy on VSI-interface 2 of VTEP 2. When receiving the NS packet sent by VTEP 1, VTEP 2 forwards it and sends an NS packet sourced from VSI-interface 2 simultaneously, and VM 2 replies to both NS packets. Then, VTEP 2 learns the MAC address of VM 2 from the NA packet sent to 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.

Use undo l2vpn m-lag peer-link tunnel to disable an M-LAG member device from automatically setting up a VXLAN tunnel with the peer M-LAG member device.

Syntax

l2vpn m-lag peer-link tunnel { source source-ipv4 destination destination-ipv4 | source source-ipv6 destination destination-ipv6 }

Default

The M-LAG member devices in an M-LAG system do not set up a VXLAN tunnel between them.

Views

Predefined user roles

network-admin

Parameters

source source-ipv4 destination destination-ipv4: Specifies source and destination IPv4 addresses for the automatically established VXLAN tunnel.

source source-ipv6 destination destination-ipv6: Specifies source and destination IPv6 addresses for the automatically established VXLAN tunnel.

Usage guidelines

This command applies to an M-LAG system that uses a direct peer link.

By default, the dynamic ACs created on the peer link use frame match criteria and VSI mappings identical to those of the site-facing ACs. If you configure the same frame match criterion for the site-facing ACs of different VSIs, the dynamic ACs created for the site-facing ACs will conflict with each other. To resolve this issue, use this command to enable the M-LAG member devices to automatically set up a VXLAN tunnel between them.

After you execute this command, the M-LAG member devices no longer create dynamic ACs on the peer link. Instead, they set up a VXLAN tunnel and assign it to all VXLANs. The VXLAN tunnel and the peer link transmit different types of traffic.

· The VXLAN tunnel is used to forward data traffic. When a site-facing AC on one M-LAG member device fails, the device forwards the remote packets destined for the AC to the other M-LAG member device over the VXLAN tunnel. The remote packets are encapsulated with the VXLAN ID of the failed site-facing AC. When the other M-LAG member device receives the packets, it decapsulates them and forwards them in the VXLAN where they belong.

· The peer link is used to exchange M-LAG protocol packets and synchronize MAC and ARP entries.

The l2vpn m-lag peer-link tunnel and l2vpn m-lag peer-link ac-match-rule vxlan-mapping commands are mutually exclusive. Do not use them together.

If you use this command on an M-LAG system that uses a VXLAN tunnel as the peer link, the M-LAG member devices do not assign the automatically established VXLAN tunnel to VXLANs and thus cannot use it to forward traffic.

To change the tunnel source and destination addresses, first execute the undo l2vpn m-lag peer-link tunnel command to delete the existing VXLAN tunnel.

Examples

# Enable the device to set up a VXLAN tunnel with its M-LAG peer. Specify the source and destination IPv4 addresses of the VXLAN tunnel as 1.1.1.1 and 2.2.2.2, respectively.

Usage guidelines

Use this command only on an EVPN network.

By default, the device issues a remote MAC address entry to the hardware after the remote MAC address is advertised to the local site by BGP EVPN routes. This feature enables the device to issue a remote MAC address entry to the hardware only when the entry is required for packet forwarding. This feature saves hardware resources on the device.

With this feature enabled, the device generates a blackhole MAC address entry for an unknown MAC address if receiving 50 frames destined for that MAC address within the MAC aging time. Those blackhole MAC address entries age out when the MAC aging timer expires. After a blackhole MAC address entry ages out, the device can forward the traffic destined for the MAC address. For more information about the MAC aging time and blackhole MAC address entries, see MAC address table configuration in Layer 2—LAN Switching Configuration Guide.

CAUTION:

After you execute this command, VXLAN tunnels might be reestablished, and transient VXLAN traffic loss might occur. As a best practice, enable BGP EVPN route reception and advertisement again after you execute this command.

By default, the device selects a default route to forward traffic if only the default route is obtained after BGP route recursion. If the default route does not point to the desired next hop, traffic forwarding will fail.

To resolve this issue, enable the device to ignore default routes in route recursion. If only the default route is obtained after route recursion is performed for a BGP route, that BGP route becomes invalid, and other BGP routes with the same prefix are selected for forwarding.

Enable this feature if multiple links exist between the device and a destination IP address. If one of the links fail, traffic will be switched to the other available links instead of being incorrectly forwarded based on a default route.

Examples

# Enable the device to ignore default routes when it performs route recursion for the BGP EVPN routes that match routing policy policy1.

Parameters

group-name: Specifies the peer group name, a case-sensitive string of 1 to 47 characters. Make sure the specified peer group already exists.

ipv4-address: Specifies the IPv4 address of the peer. Make sure the peer already exists.

mask-length: Specifies the IPv4 address mask in the range of 0 to 32. If you specify this argument, it indicates a dynamic peer in the specified network segment.

ipv6-address: Specifies the IPv6 address of the peer. Make sure the peer already exists.

prefix-length: Specifies the IPv6 prefix length in the range of 0 to 128. If you specify this argument, it indicates a dynamic peer in the specified network segment.

split-group-name: Specifies the name of the horizontal split group, a case-sensitive string of 1 to 31 characters.

Usage guidelines

Operating mechanism

The horizontal split group is a configuration strategy. After you execute this command, the specified peer/peer group joins the designated horizontal split group. The device will not forward traffic received from peers within a horizontal split group to other peers in the same group. It can still forward traffic to peers in different horizontal split groups or to peers that have not been assigned to a horizontal split group. As a result, precise traffic control can be implemented by setting up horizontal split groups, thereby avoiding unnecessary traffic transmission and the creation of loops.

In the EVPN data center interconnect scenario, by assigning the EDs of different data centers to the same horizontal split group, horizontal segmentation of traffic from remote data center EDs can be achieved. This prevents the traffic from being forwarded to the EDs of other data centers, thus avoiding potential routing loops.

Restrictions and guidelines

The horizontal split group has only local significance, which means that this configuration is effective only on the current device.

# Configure BGP EVPN peer 1.1.1.1 to join horizontal split group group1.

policy vpn-target

Use policy vpn-target to enable route target filtering for BGP EVPN routes.

Use undo policy vpn-target to disable route target filtering for BGP EVPN routes.

Syntax

undo policy vpn-target

Default

Route target filtering is enabled for BGP EVPN routes.

Views

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.

reset evpn route mac-mobility suppression

Use reset evpn route mac-mobility suppression to cancel MAC mobility event suppression.

Syntax

reset evpn route mac-mobility suppression [ vsi vsi-name [ mac mac-address ] ]

Views

User view

Predefined user roles

network-admin

Parameters

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

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

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

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.

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.

Examples

# Configure 22:1 as the RD of the EVPN instance on VSI aaa.

Parameters

ext-comm-list-number: Specifies an extended community attribute list by its number in the range of 1 to 65535.

Usage guidelines

This command enables an RR to reflect only received BGP EVPN routes that match the attributes in the specified extended community attribute list.

If a cluster contains multiple RRs, you can configure different reflection policies on the RRs for load sharing among the RRs.

For more information about the extended community attribute list, see Layer 3—IP Routing Configuration Guide.

snmp-agent trap enable evpn

Use snmp-agent trap enable evpn to enable SNMP notifications for EVPN.

Syntax

snmp-agent trap enable evpn [ mac-mobility-suppression ]

undo snmp-agent trap enable evpn [ mac-mobility-suppression ]

Views

System view

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.

Predefined user roles

network-admin

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 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.

Examples

# Configure import route targets 10:1, 100:1, and 1000:1 for the EVPN instance on VSI aaa.
