The output shows that Router A communicates with Router B through GigabitEthernet 2/1/2.

Network requirements
As shown in Figure 90:
• Router A has a route to interface Loopback 1 (2::9/128) on Router B, and the output interface is
GigabitEthernet 2/1/1.
• Router B has a route to interface Loopback 1 (1::9/128) on Router A, and the output interface is
GigabitEthernet 2/1/1.
• Router D has a route to 1::9/128, and the output interface is GigabitEthernet 2/1/1. It also has a
route to 2::9/128, and the output interface is GigabitEthernet 2/1/2.
Configure the following:
• Configure an IPv6 static route to subnet 120::/64 on Router A.
• Configure an IPv6 static route to subnet 121::/64 on Router B.
• Enable BFD for both routes.
• Configure an IPv6 static route to subnet 120::/64 and an IPv6 static route to subnet 121::/64 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.
