Configuring BFD for OSPF
Network requirements
As shown in
, 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.
