The frr-policy route command configures a filtering policy to allow IS-IS to filter the IS-IS backup routes to be added in the IP routing table.

VPN FRR(fast reroute) to ensure VPN service switchover to a secondary link when the primary link between PEs fails.VPN FRR is used in PE multi-homing scenarios to enhance network reliability. If the primary link fails, VPN FRR quickly switches traffic to the backup link to minimize the impact of the link failure on VPN services.
