Network requirements
As shown in Figure 5 , configure static routes on Switch A, Switch B, and Switch C, and configure static
route FRR. When Link A becomes unidirectional, traffic can be switched to Link B immediately.

Configuration procedure
1. Configure IP addresses for interfaces. (Details not shown.)
2. Configure static route FRR on link A by using one of the following methods:
{
(Method 1.) Specify a backup next hop for static route FRR:
# Configure a static route on Switch A, and specify VLAN-interface 100 as the backup output
interface and 12.12.12.2 as the backup next hop.
