Network requirements
In Figure 4, Router A has a route to interface Loopback 1 (2.2.2.9/32) on Router B, with the outgoing
interface GigabitEthernet 2/1/1. Router B has a route to interface Loopback 1 (1.1.1.9/32) on Router A,
with the outgoing interface GigabitEthernet 2/1/1. Router D has a route to 1.1.1.9/32, with the outgoing
interface GigabitEthernet 2/1/1, and a route to 2.2.2.9/32, with the outgoing interface GigabitEthernet
2/1/2.
Configure a static route to subnet 120.1.1.0/24 on Router A, configure a static route to subnet
121.1.1.0/24 on Router B, and enable BFD for both routes. Configure a static route to subnet 120.1.1.0/24
and a static route to subnet 121.1.1.0/24 on both Router C and Router D. When the link between Router
A and Router B through Router D fails, BFD can detect the failure immediately and Router A and Router
B can communicate through Router C.
