Predefined user roles
network-admin
Parameters
virtual-vtep-ip: Specifies the virtual VTEP address.
Usage guidelines
EVPN distributed relay virtualizes two VTEPs or EVPN gateways into one DR system to avoid single points of failure. The VTEPs or EVPN gateways use a virtual VTEP address to establish VXLAN tunnels to remote devices.
For the device to re-establish VXLAN tunnels, you must execute the address-family l2vpn evpn command in BGP instance view after you enable or disable EVPN distributed relay.
To modify the virtual VTEP address, you must first delete the original virtual VTEP address.
Examples
# Enable EVPN distributed relay and specify the virtual VTEP address as 1.1.1.1.

Predefined user roles
network-admin
Parameters
local local-ip: Specifies the IP address of the local VTEP.
remote remote-ip: Specifies the IP address of the peer VTEP.
Usage guidelines
An AC that is attached to only one of the VTEPs in a DR system is called a single-armed AC. After you configure this command, each VTEP in a DR system changes the next hop of the routes for single-armed ACs to its local VTEP IP address when advertising the routes. This ensures that the traffic of a single-armed AC is forwarded to its attached VTEP. When a VTEP receives BGP EVPN routes from the peer VTEP IP address specified by using this command, it does not set up a VXLAN tunnel to the peer VTEP.
You must execute this command if single-armed ACs are attached to a DR system that uses an Ethernet aggregate link as the IPL. You do not need to execute this command on a DR system that uses a VXLAN tunnel as the IPL. In such a DR system, a VTEP uses the source IP address of the IPL as the next hop of routes for single-armed ACs to ensure correct traffic forwarding.
When you execute this command, make sure the IP address of the local VTEP belongs to a local interface. Make sure the local VTEP IP address and peer VTEP IP address are reversed on the VTEPs in a DR system.
Examples
# Specify the IP addresses of the local and peer VTEPs in the DR system as 2.2.2.2 and 3.3.3.3, 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. 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.

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 discovery, MAC reachability information advertisement, and host route advertisement. MP-BGP uses the RD to differentiate BGP EVPN routes of different EVPN instances.

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.
