BFD for IS-IS configuration example
Network requirements
• As shown in Figure 44, run IS-IS on Switch A, Switch B and Switch C so that can reach 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.

Configuration procedure
1. Configure IP addresses for interfaces. (Details not shown.)
2. Configure basic IS-IS:
# Configure Switch A.
