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

Network requirements
As shown in Figure 84 :
• Switch A has a route to interface Loopback 1 (2::9/128) on Switch B, and the output interface is
VLAN-interface 10.
• Switch B has a route to interface Loopback 1 (1::9/128) on Switch A, and the output interface is
VLAN-interface 12.
• Switch D has a route to 1::9/128, and the output interface is VLAN-interface 10. It also has a route
to 2::9/128, and the output interface is VLAN-interface 12.
Configure the following:
• Configure an IPv6 static route to subnet 120::/64 on Switch A.
• Configure an IPv6 static route to subnet 121::/64 on Switch 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 Switch C and Switch D.
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.
