Static route FRR configuration example
Network requirements
Figure 5 shows that Switch S, Switch A, and Switch D are interconnected through static routes. Configure
static route FRR so that when Link A between Switch S and Switch D fails, traffic can be switched to Link
B immediately.

Configuration procedure
1. Configure IP addresses for the interfaces. (Details not shown.)
2. Configure static routes:
Configure static routes on Switch S, Switch A, and Switch D so that Switch S can reach Loopback
0 on Switch D and Switch D can reach Loopback 0 on Switch S.
# Configure a static route on Switch S.
<SwitchS> system-view
[SwitchS] ip route-static 4.4.4.4 32 vlan-interface 200 13.13.13.2
# Configure a static route on Switch D.
<SwitchD> system-view
[SwitchD] ip route-static 1.1.1.1 32 vlan-interface 200 13.13.13.1
# Configure a static route on Switch A.
<SwitchA> system-view
[SwitchA] ip route-static 4.4.4.4 32 vlan-interface 101 24.24.24.4
[SwitchA] ip route-static 1.1.1.1 32 vlan-interface 100 12.12.12.1
3. Configure static route FRR:
# Configure Switch S.
