Usage guidelines
This command sets a backup link in the routing policy for FRR.
Using the routing policy, a routing protocol can designate a backup link for specific routes to implement
FRR. When the primary link fails, FRR immediately directs packets to the backup link to minimize
interruption time.
Examples
# Configure node 10 of routing policy policy1 to set the backup output interface VLAN-interface 1 and
backup next hop 193.1.1.8 for the route destined to 100.1.1.0/24.
<Sysname> system-view
[Sysname] ip prefix-list abc index 10 permit 100.1.1.0 24
[Sysname] route-policy policy1 permit node 10
[Sysname-route-policy-policy1-10] if-match ip address prefix-list abc
[Sysname-route-policy-policy1-10] apply fast-reroute backup-interface vlan-interface 1
backup-nexthop 193.1.1.8
apply ip-address next-hop

Parameters
ip-address: Specifies the next hop IP address.
public: Specifies the public network.
vpn-instance vpn-instance-name: Specifies an MPLS L3VPN instance by its name, a case-sensitive string
of 1 to 31 characters.
Usage guidelines
This command cannot set a next hop for redistributed routes.
If you do not provide the public keyword or vpn-instance vpn-instance-name option for this command,
the next hop belongs to the public network.
Examples
# Configure node 10 in permit mode for routing policy policy1 to set next hop 193.1.1.8 for routes
matching AS path list 1.
