Configuring BFD for OSPF
Network requirements
z Switch A and Switch B are interconnected through a Layer 2 switch. BFD is enabled on the switch
interfaces. OSPF is enabled on the switches that are reachable to each other at the network layer.
z When the link between Switch B and the Layer 2 switch fails, BFD can quickly detect the failure
and notify OSPF of the failure.
