Configuring BFD for OSPF
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
Follow these steps to enable BFD control packet bidirectional detection on an OSPF interface:
To do…
Use the command…

NOTE: 
• 
One network segment can only belong to one area.
•
Both ends of a BFD session must be on the same network segment and in the same area.
