Parameters
route-policy: References a routing policy by its name, a string of 1 to 63 case-sensitive characters.
Usage guidelines
MPLS L3VPN FRR is applicable to a dual-homed scenario where a CE is connected to two PEs.
The referenced routing policy must have the apply fast-reroute backup-nexthop command configured to
specify the backup next hop.
For more information about the apply fast-reroute backup-nexthop and route-policy commands, see
Layer 3—IP Routing Command Reference.
Examples
# Configure FRR for the VPN instance vpn1 and reference the routing policy poly-1 to specify the backup
next hop as 3.3.3.3.
<Sysname> system-view
[Sysname] route-policy poly-1 permit node 10
[Sysname-route-policy] apply fast-reroute backup-nexthop 3.3.3.3
[Sysname-route-policy] quit
[Sysname] ip vpn-instance vpn1
[Sysname-vpn-instance-vpn1] fast-reroute route-policy poly-1
