RIP FRR configuration example
Network requirements
As shown in Figure 14, Switch S, Switch A, and Switch D are interconnected through RIPv2. Configure RIP
FRR so that when Link A becomes unidirectional, services can be switched to Link B immediately.

Configuration procedure
1. Configure IP addresses and subnet masks for interfaces on the switches. (Details not shown.)
2. Configure RIPv2 on the switches to make sure Switch A, Switch D, and Switch S can communicate
with each other at Layer 3. (Details not shown.)
3. Configure RIP FRR:
# Configure Switch S.
<SwitchS> system-view
[SwitchS] bfd echo-source-ip 1.1.1.1
[SwitchS] ip ip-prefix abc index 10 permit 4.4.4.4 32
[SwitchS] route-policy frr permit node 10
[SwitchS-route-policy] if-match ip-prefix abc
[SwitchS-route-policy] apply fast-reroute backup-interface vlan-interface 100
backup-nexthop 12.12.12.2
[SwitchS-route-policy] quit
[SwitchS] rip 1
[SwitchS-rip-1] fast-reroute route-policy frr
[SwitchS-rip-1] quit
# Configure Switch D.
<SwitchD> system-view
[SwitchD] bfd echo-source-ip 4.4.4.4
[SwitchD] ip ip-prefix abc index 10 permit 1.1.1.1 32
[SwitchD] route-policy frr permit node 10
[SwitchD-route-policy] if-match ip-prefix abc
[SwitchD-route-policy] apply fast-reroute backup-interface vlan-interface 101
backup-nexthop 24.24.24.2
[SwitchD-route-policy] quit
[SwitchD] rip 1
[SwitchD-rip-1] fast-reroute route-policy frr
[SwitchD-rip-1] quit
4. Verify the configuration:
# Display route 4.4.4.4/32 on Switch S to view the backup next hop information.
