RIP FRR configuration example
Network requirements
As shown in Figure 14 , Switch A, Switch B, and Switch C run RIPv2. Configure RIP FRR so that when Link
A becomes unidirectional, services can be switched to Link B immediately.
Figure 14 Network diagram
Table 8 Interface and IP address assignment
Device Interface IP address
Switch A VLAN-interface 100 12.12.12.1/24
Switch A VLAN-interface 200 13.13.13.1/24
Switch A Loopback 0 1.1.1.1/32
Switch B VLAN-interface 101 24.24.24.4/24
Switch B VLAN-interface 202 13.13.13.2/24
Switch B Loopback 0 4.4.4.4/32
Switch C VLAN-interface 100 12.12.12.2/24
Switch C VLAN-interface 101 24.24.24.2/24
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] bfd echo-source-ip 2.2.2.2
[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
