Configuring BFD for OSPF
BFD provides a single mechanism to quickly detect and monitor the connectivity of links between OSPF
neighbors, which improves the network convergence speed. For more information about BFD, see High
Availability Configuration Guide.
OSPF supports the following BFD detection modes:
• Bidirectional control detection—Requires BFD configuration to be made on both OSPF routers on
the link.
• Single-hop echo detection—Requires BFD configuration to be made on one OSPF router on the link.
