BFD for IS-IS configuration example

Network requirements
•
As shown in
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.
Figure 56, IS-IS is enabled on Switch A, Switch B and Switch C that are reachable
