BFD for IPv6 IS-IS configuration example

Network requirements
As shown in
•
Configure IPv6 IS-IS on Switch A and Switch B so that they can reach other.
•
Enable BFD on VLAN-interface 10 of Switch A and Switch B.
After the link between Switch B and the Layer-2 switch fails, BFD can quickly detect the failure and
notify IPv6 IS-IS of the failure. Then Switch A and Switch B communicate through Switch C.
