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 B, and Switch C can
communicate with each other at Layer 3. (Details not shown.)
3. Configure RIP FRR:
# Configure Switch A.
<SwitchA> system-view
[SwitchA] ip prefix-list abc index 10 permit 4.4.4.4 32
[SwitchA] route-policy frr permit node 10
[SwitchA-route-policy-frr-10] if-match ip address prefix-list abc
[SwitchA-route-policy-frr-10] apply fast-reroute backup-interface vlan-interface
100 backup-nexthop 12.12.12.2
[SwitchA-route-policy-frr-10] quit
[SwitchA] rip 1
[SwitchA-rip-1] fast-reroute route-policy frr
[SwitchA-rip-1] quit
# Configure Switch B.
<SwitchB> system-view
[SwitchB] ip prefix-list abc index 10 permit 1.1.1.1 32
[SwitchB] route-policy frr permit node 10
[SwitchB-route-policy-frr-10] if-match ip address prefix-list abc
[SwitchB-route-policy-frr-10] apply fast-reroute backup-interface vlan-interface
101 backup-nexthop 24.24.24.2
[SwitchB-route-policy-frr-10] quit
[SwitchB] rip 1
[SwitchB-rip-1] fast-reroute route-policy frr
[SwitchB-rip-1] quit
Verifying the configuration
# Display route 4.4.4.4/32 on Switch A to view the backup next hop information.
[SwitchA] display ip routing-table 4.4.4.4 verbose
Summary Count : 1
Destination: 4.4.4.4/32
Protocol: RIP
Process ID: 1
