Configuring BFD for OSPF
Network requirements
As shown in
OSPF is enabled on Router A, Router B, and Router C so that they are reachable to each other at
•
the network layer.
After the link over which Router A and Router B communicate through a Layer 2 switch fails, BFD
•
can quickly detect the failure and notify OSPF of the failure. Router A and Router B then
communicate through Router C.
