Default
No virtual ED address is configured.
Views
System view
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.
Examples
# Configure 1.2.3.4 as the virtual ED address.
<Sysname> system-view
[Sysname] evpn edge group 1.2.3.4

Parameters
vxlan-id: Specifies a VXLAN ID in the range of 0 to 16777215.
Usage guidelines
On distributed EVPN gateways, you must configure L3 VXLAN IDs for the gateways to differentiate traffic of different VPN instances.
To forward Layer 3 traffic of a VPN instance, you must assign an L3 VXLAN ID to the VSI interface of the VPN instance. To forward Layer 3 traffic of the public network, you must assign the same L3 VXLAN ID to the public instance and the VSI interface of the public instance.
To modify the L3 VXLAN ID for the public instance, you must first delete the original L3 VXLAN ID.
Examples
# Configure the L3 VXLAN ID as 1000 for VSI-interface 100.

Parameters
vxlan-id: Specifies a remote VXLAN ID in the range of 0 to 16777215.
Usage guidelines
The VXLAN mapping feature provides Layer 2 connectivity for a tenant subnet that uses different VXLAN IDs in multiple data centers.
VXLAN mapping includes the following types:
· Non-intermediate VXLAN mapping—When two data centers use different VXLAN IDs for a subnet, map the local VXLAN to the remote VXLAN on the ED of one data center. For example, for VXLAN 10 of data center 1 to communicate with VXLAN 20 of data center 2, map VXLAN 10 to VXLAN 20 on the ED of data center 1.
· Intermediate VXLAN mapping—When multiple data centers use different VXLAN IDs for a subnet, map the VXLANs to an intermediate VXLAN on all EDs. For example, data center 1 uses VXLAN 10, data center 2 uses VXLAN 20, and data center 3 uses VXLAN 30. To provide connectivity for the VXLANs, map them to intermediate VXLAN 500 on EDs of the data centers. You must use intermediate VXLAN mapping if more than two data centers use different VXLAN IDs. The intermediate VXLAN can be used only for VXLAN mapping, and it cannot be used for common VXLAN services.
You must create mapped remote VXLANs on the device, create an EVPN instance for each remote VXLAN, and configure RD and route target settings for the EVPN instances.
A mapped remote VXLAN ID cannot be the reserved VXLAN ID specified by using the reserved vxlan command.
Examples
# Map local VXLAN 100 to remote VXLAN 200.
<Sysname> system-view
[Sysname] vsi aaa
[Sysname-vsi-aaa] vxlan 100
[Sysname-vsi-aaa-vxlan-100] quit

peer next-hop-invariable
Use peer next-hop-invariable to configure the device to not change the next hop of routes advertised to an EBGP peer or peer group.
Use undo peer next-hop-invariable to configure the device to use its address as the next hop of routes advertised to an EBGP peer or peer group.
Syntax
peer { group-name | ipv4-address [ mask-length ] } next-hop-invariable
undo peer { group-name | ipv4-address [ mask-length ] } next-hop-invariable
Default
The device uses its address as the next hop of routes advertised to EBGP peers or peer groups.
Views
BGP EVPN address family view
Predefined user roles
network-admin
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.
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.
Examples
# Configure the device to not change the next hop of routes advertised to EBGP peer 1.1.1.1.
<Sysname> system-view

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
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.

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.
