Configuring BFD for OSPF
Bidirectional forwarding detection (BFD) provides a single mechanism to quickly detect and monitor the
connectivity of links between OSPF neighbors, reducing network convergence time. For more information
about BFD, see High Availability Configuration Guide.
OSPF supports the following BFD detection methods:
• Control packet bidirectional detection, which requires BFD configuration to be made on both OSPF
routers on the link.
• Echo packet single-hop detection, which requires BFD configuration to be made on one OSPF router
on the link.
Configuring control packet bidirectional detection
Both ends of a BFD session must be on the same network segment and in the same area. One network
segment can only belong to one area.
To enable BFD control packet bidirectional detection on an OSPF interface:
