Configuring BFD for OSPF

Network requirements

As shown in

Figure 51

, OSPF 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 a Layer 2 switch fails, BFD can

quickly detect the failure and notify OSPF of the failure. Then Switch A and Switch B communicate

through Switch C.
