ac interface

Use ac interface to map an interface to a cross-connect.

Use undo ac interface to delete the mapping between a cross-connect and an interface.

Syntax

ac interface interface-type interface-number [ access-mode { ethernet | vlan } ] [ track track-entry-number&<1-3> ]

undo ac interface interface-type interface-number

Default

No interface is mapped to a cross-connect.

Views

Predefined user roles

network-admin

Parameters

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

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

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

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

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

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.

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.

Examples

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

[Sysname] xconnect-group vpna

[Sysname-xcg-vpna] connection aaa

[Sysname-xcg-vpna-aaa] ac interface gigabitethernet 1/0/1

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.

Examples

# Disable ARP information advertisement for an EVPN instance.

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 or UPWs 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.

· 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 do not specify the no-split-horizon keyword when executing the peer command for the PW.

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

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.

Non-revertive mode for preference-based DF election takes effect after the evpn df-election algorithm preference command is executed in interface or system view.

Examples

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

Predefined user roles

network-admin

Parameters

group-ip: Specifies the virtual 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 does not 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.

network-admin

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 corresponding 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.

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

Usage guidelines

Remote FRR enables two PEs on an EVPN VPWS 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 only cross-connect group EVPN instances that use MPLS encapsulation.

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

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 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.

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.

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 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 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.

You can set the redundancy mode for a VSI LDP PW or VSI static PW only if you do not specify the no-split-horizon keyword when executing the peer command for the PW.

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.

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

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

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.

Examples

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

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.

This evpn track peer 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.

network-admin

Usage guidelines

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

At a multihomed EVPN VPLS 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 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, VSI-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.

Parameters

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

ipv4-address: Specifies a peer by its IPv4 address.

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.

Usage guidelines

When you use this command and the peer next-hop-local command, follow these restrictions:

· The peer next-hop-invariable command is exclusive with the peer next-hop-local command. You can execute only one of these commands for a peer or peer group.

· If you have executed the peer next-hop-invariable command for a peer group, you cannot execute the peer next-hop-local command for any peer in the peer group.

· When you execute the peer next-hop-local command for a peer group whose members already have the peer next-hop-invariable setting, the peer next-hop-local command overwrites that setting.

The next hop in BGP EVPN routes is the IP address of the originating VTEP. By default, the device replaces the next hop of IBGP routes with its address when advertising the routes to an EBGP peer. If the device is a transport network device, it will modify the next hop of BGP EVPN routes. For VTEPs to learn one another's IP address, you must configure the device to not change the next hop of routes advertised to EBGP peers.

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.

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.

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

Examples

# Specify PW class pw100 for the EVPN instance on VSI vpna.

<Sysname> system-view

[Sysname] vsi vpna

[Sysname-vsi-vpna] evpn encapsulation mpls

[Sysname-vsi-vpna-evpn-mpls] pw-class pw100

route-distinguisher (EVPN instance view)

Use route-distinguisher to configure an RD for an EVPN instance.

Use undo route-distinguisher to restore the default.

Syntax

route-distinguisher { route-distinguisher | auto }

undo route-distinguisher

Default

No RD is configured for an EVPN instance.

Views

EVPN instance view

Predefined user roles

network-admin

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.

Examples

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

<Sysname> system-view

[Sysname] vsi aaa

[Sysname-vsi-aaa] evpn encapsulation vxlan

[Sysname-vsi-aaa-evpn-vxlan] route-distinguisher 22:1

route-distinguisher (public instance view)

Use route-distinguisher to configure an RD for the public instance.

Use undo route-distinguisher to restore the default.

Syntax

route-distinguisher route-distinguisher

undo route-distinguisher

Default

No RD is configured for the public instance.

Views

Parameters

route-distinguisher: Specifies an RD, a string of 3 to 21 characters. The RD 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.

Usage guidelines

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

Examples

# Configure 22:1 as the RD of the public instance.

<Sysname> system-view

[Sysname] ip public-instance

[Sysname-public-instance] route-distinguisher 22:1

rr-filter

Use rr-filter to create a route reflector (RR) reflection policy.

Use undo rr-filter to restore the default.

Syntax

rr-filter ext-comm-list-number

undo rr-filter

Default

An RR does not filter reflected BGP EVPN routes.

Views

BGP EVPN address family view

Predefined user roles

network-admin

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.

Examples

# Configure a reflection policy for the device to reflect BGP EVPN routes that match extended community attribute list 10.

tunnel-policy

Use tunnel-policy to specify a tunnel policy for a VSI EVPN instance.

Use undo tunnel-policy to restore the default.

Syntax

tunnel-policy tunnel-policy-name

undo tunnel-policy

Default

No tunnel policy is specified for a VSI EVPN instance.

Views

VSI EVPN instance view

Predefined user roles

network-admin

Parameters

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

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.

<Sysname> system-view

[Sysname] vsi aa

[Sysname-vsi-aa] evpn encapsulation mpls

[Sysname-vsi-aa-evpn-mpls] tunnel-policy policy1

vpn-route cross multipath

Use vpn-route cross multipath to enable ECMP VPN route redistribution.

Use undo vpn-route cross multipath to disable ECMP VPN route redistribution.

Syntax

vpn-route cross multipath

undo vpn-route cross multipath

Default

ECMP VPN route redistribution is disabled. If multiple routes have the same prefix and RD, BGP only imports the optimal route into the EVPN routing table.

Views

Predefined user roles

network-admin

Usage guidelines

ECMP VPN route redistribution enables BGP to import all routes that have the same prefix and RD into the EVPN routing table.

Examples

# Enable ECMP VPN route redistribution.

vpn-target

Use vpn-target to configure route targets for EVPN.

Use undo vpn-target to delete route targets for EVPN.

Syntax

In VSI EVPN instance view:

vpn-target { vpn-target&<1-8> | auto } [ both | export-extcommunity | import-extcommunity ]

undo vpn-target { vpn-target&<1-8> | auto | all } [ both | export-extcommunity | import-extcommunity ]

In VPN instance EVPN view, public instance IPv4 address family view, or public instance EVPN view:

vpn-target vpn-target&<1-8> [ both | export-extcommunity | import-extcommunity ]

undo vpn-target { all | vpn-target&<1-8> [ both | export-extcommunity | import-extcommunity ] }

Default

EVPN does not have route targets.

Views

VSI EVPN instance view

VPN instance EVPN view

Public instance EVPN view

Public instance IPv4 address family view

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 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.

In an EVPN VPLS network, you must configure unique route targets for VPN instances on the same PE. If you fail to do so, EVPN instances will receive incorrect routes and use incorrect MPLS labels for PW setup.

Examples

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

<Sysname> system-view

[Sysname] vsi aaa

[Sysname-vsi-aaa] evpn encapsulation vxlan
