Configuring static route FRR

NOTE:
Only the A5500 EI Switch Series supports static route FRR.
A link or router failure on a path can cause packet loss and even routing loop. Static route fast reroute
(FRR) enables fast rerouting to minimize the impact of link or node failures.

routes matching the specified criteria. Packets are directed to the backup next hop to avoid traffic
interruption.

Configuration prerequisites

Configuring static route FRR needs to reference a routing policy. You can specify a backup next hop in
a routing policy by using the apply fast-reroute backup-interface command. For more information about
the command and routing policy configurations, see
