The output shows that Switch A communicates with Switch B through VLAN-interface 11 now.

BFD for static routes configuration example (indirect next hop)

Network requirements
As shown in
interface VLAN-interface 10. Switch B has a route to interface Loopback1 (1.1.1.9/32) on Switch A, with
output interface VLAN-interface 12. Switch D has a route to 1.1.1.9/32, with output interface
VLAN-interface 10, and a route to 2.2.2.9/32, with output 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.
