•
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
To enable BFD control packet bidirectional detection on an OSPF interface:
Step Command
Description
1.
Enter system view.
system-view
N/A
2.
Enable an OSPF process and enter OSPF
view.
ospf [ process-id | router-id router-id |
vpn-instance vpn-instance-name ] *
N/A
3.
Specify a network to enable OSPF on the
interface attached to the network.
network ip-address wildcard-mask
Not specified by
default
4.
Exit to system view.
quit
N/A
5.
Enter interface view.
interface interface-type
interface-number
N/A
6.
Enable BFD control packet bidirectional
detection on the interface.
ospf bfd enable
Not enabled by
default
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.
