PurposeCommand or Action
(Optional) Returns the device to global configuration
mode. Enter this command only if you want to perform
Step 7 to disable BFD for one or more interfaces.
exit
Example:
Device(config-router)# exit
Step 5
(Optional) Enters interface configuration mode. Enter
this command only if you want to perform Step 7 to
disable BFD for one or more interfaces.
interface type number
Example:
Device(config)# interface
fastethernet 6/0
Step 6
(Optional) Disables BFD on a per-interface basis for one
or more interfaces associated with the OSPF routing
process.
ip ospf bfd [disable]
Example:
Device(config-if)# ip ospf bfd
disable
Step 7
You should use the disable keyword only if you
enabled BFD on all of the interfaces that OSPF
is associated with using the bfd all-interfaces
command in router configuration mode.
Note
Exits interface configuration mode and returns the router
to privileged EXEC mode.
end
Example:
Device(config-if)# end
Step 8
(Optional) Displays information that can help verify if
the BFD neighbor is active and displays the routing
protocols that BFD has registered.
show bfd neighbors [details]
Example:
Device# show bfd neighbors
detail
Step 9
(Optional) Displays information that can help verify if
BFD for OSPF has been enabled.
show ip ospf
Example:
Device# show ip ospf
Step 10
Configuring BFD Support for OSPF for One or More Interfaces
To configure BFD on one or more OSPF interfaces, perform the steps in this section.
Before You Begin
OSPF must be running on all participating routers.
The baseline parameters for BFD sessions on the interfaces over which you want to run BFD sessions to BFD
neighbors must be configured. See the Configuring BFD Session Parameters on the Interface section for more
information.
