Configuring BFD for IS-IS
Network requirements
• As shown in Figure 70 , IS-IS is enabled on Router A, Router B and Router C that are reachable to
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.
