BFD for IPv6 IS-IS configuration example
Network requirements
•
As shown in
BFD over the link Switch A<—>L2 Switch<—>Switch B.
•
When 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.
