Configuring BFD for IS-IS
Network requirements
•
As shown in
, IS-IS is enabled on Switch A, Switch B and Switch C that are reachable to
each other at the network layer.
•
After the link over which Switch A and Switch B communicate through the Layer-2 switch fails, BFD
can quickly detect the failure and notify IS-IS of the failure. Switch A and Switch B then communicate
through Switch C.
