Configuring BFD for IS-IS

Network requirements
As shown in
•
each other at the network layer.
• After the link over which Router A and Router B communicate through the Layer-2 switch fails, BFD
can quickly detect the failure and notify IS-IS of the failure. Router A and Router B then communicate
through Router C.
Figure 47, IS-IS is enabled on Router A, Router B and Router C that are reachable to
