The output shows that Switch A communicates with Switch B through VLAN-interface 11.
BFD for IPv6 static routes configuration example (indirect
next hop)
Network requirements
As shown in
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.
