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:
Step
Enter system view.
1.
Enable an OSPF process and enter
2.

process in the area.
Exit to system view.
4.
Enter interface view.
