Network requirements
• As shown in
1050H
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.
