Configuring BFD for IS-IS
Network requirements
As shown in Figure 72 , 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. Then Switch A and Switch B communicate through
Switch C.
