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
[Sysname-bgp-default-vpn1] address-family ipv4
[Sysname-bgp-default-ipv4-vpn1] advertise l2vpn evpn
arp mac-learning disable
Use arp mac-learning disable to disable a VSI EVPN instance from learning MAC addresses from ARP information.
Use undo arp mac-learning disable to restore the default.
Syntax
arp mac-learning disable
undo arp mac-learning disable
Default
An EVPN instance learns MAC addresses from ARP information.

Usage guidelines
The MAC information and ARP information advertised by a remote VTEP overlap. To avoid duplication, use this command to disable the learning of MAC addresses from ARP information. EVPN will learn remote MAC addresses only from the MAC information advertised from remote sites.
Examples
# Disable a VSI EVPN instance from learning MAC addresses from ARP information.
<Sysname> system-view
[Sysname] vsi aaa
[Sysname-vsi-aaa] evpn encapsulation vxlan

Views
System view
Predefined user roles
network-admin
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 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. This feature allows an IP address to move at most four times from a site within 180 seconds. If an IP address moves more than four times within 180 seconds, the VTEP at the site will suppress the excess MAC mobility events and will not advertise information about the MAC address.
After you execute the undo evpn route mac-mobility suppression command, a VTEP 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.

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.

· 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.
