Implementing BFD

Enabling BFD for OSPF on an Interface

The following procedures describe how to configure BFD for Open Shortest Path First (OSPF) on an interface.
The steps in the procedure are common to the steps for configuring BFD on IS-IS ; only the command mode
differs.
SUMMARY STEPS
1. configure
2. router ospf process-name
3. interface type interface-path-id
4. bfd fast-detect
5. bfd minimum-interval milliseconds
6. bfd multiplier multiplier
7. area area-id
8. commit
DETAILED STEPS
Command or Action
Step 1 configure
Step 2 router ospf process-name
Example:
RP/0/RP0/CPU0:router(config)# router ospf 0
Step 3 interface type interface-path-id
Example:
RP/0/RP0/CPU0:router(config-ospf)#
TengigabitEthernet 0/3/0/1
Step 4
bfd fast-detect
Example:
RP/0/RP0/CPU0:router(config-ospf-if)#
fast-detect
Step 5 bfd minimum-interval milliseconds
Example:
RP/0/RP0/CPU0:router(config-ospf-if)# bfd
minimum-interval 6500
Step 6 bfd multiplier multiplier
Example:
Purpose
Enters OSPF configuration mode, allowing you to configure
the OSPF routing process.
Note
Enters interface configuration mode and specifies the
interface name.
interface
Enables BFD to detect failures in the path between adjacent
forwarding engines.
bfd
Sets the BFD minimum interval. Range is 15-30000
milliseconds.
This example sets the BFD minimum interval to 6500
milliseconds.
Sets the BFD multiplier. This is optional, by default the
multiplier will be 3 for all protocols.
This example sets the BFD multiplier to 7.
