•
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:

Follow these steps to enable BFD echo packet single-hop detection on an OSPF interface:
Use the command...
graceful-restart help { acl-number
| prefix prefix-list }
Use the command...
reset ospf [ process-id ] process
graceful-restart
Use the command...
