Network requirements
As shown in Figure 5 , Switch A has a route to interface Loopback1 (2.2.2.9/32) on Switch B, with
outbound interface VLAN-interface 10. Switch B has a route to interface Loopback1 (1.1.1.9/32) on
Switch A, with outbound interface VLAN-interface 12. Switch D has a route to 1.1.1.9/32, with outbound
interface VLAN-interface 10, and a route to 2.2.2.9/32, with outbound interface VLAN-interface 12.
Configure static routes to subnet 120.1.1.0/24 on Switch A, static routes to subnet 121.1.1.0/24 on Switch
B, and static routes to subnets 120.1.1.0/24 and 121.1.1.0/24 on both Switch C and Switch D. Enable BFD
so that when the link between Switch A and Switch B through Switch D fails, BFD can detect the failure
immediately and Switch A and Switch B can communicate through Switch C.

Configuration procedure
1. Configure IP addresses for the interfaces. (Details not shown)
2. Configure BFD.
# Configure static routes on Switch A and enable BFD control packet mode for the static route through
Switch D.
