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

hop)
Network requirements
In Figure 82, Router A has a route to interface Loopback 1 (2::9/128) on Router B, with the output
interface being Ethernet 1/1. Router B has a route to interface Loopback 1 (1::9/128) on Router A, with
the output interface being Ethernet 1/1. Router D has a route to 1::9/128, with the output interface being
Ethernet 1/1, and a route to 2::9/128, with the output interface being Ethernet 1/2.
Configure an IPv6 static route to subnet 120::/64 on Router A, and 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.
