Description
Enable fast reroute egress link protection (ELP) on provider edge (PE) devices for access links to multihomed customer edge (CE) devices in an EVPN-VXLAN fabric. This feature helps to minimize load-balanced traffic loss when the link from a PE device to a multihomed CE device goes down.
Remote sources load balance traffic toward a multihomed CE device by distributing portions of the traffic among the multihoming peer PE devices. When you enable this feature on a multihoming PE device, the device creates a backup VXLAN tunnel called an egress link protection (ELP) tunnel to each of its multihoming peer PE devices. If the PE device link to the CE device goes down, the PE device reroutes its portion of the load-balanced traffic to its peer PE devices on the ELP tunnels. The peer PE devices then send the excess load-balanced traffic to the CE device.
The PE device reroutes traffic on the ELP tunnels only until the source device routing table converges. Then the source device stops sending any traffic to the PE device with the bad link, and load balances the traffic only to the other peer PE devices.
To enable this feature, configure this statement and specify an IP address for the ELP tunnel.
Default
Fast reroute egress link protection is not enabled.
