PurposeCommand or Action
Enables BFD fast detection.bfd fast-detect
Example:
RP/0/RSP0/CPU0:router(config-if)#bfd
fast-detect
Step 3
Configures hello interval in milliseconds.
bfd minimum-intervalmilliseconds
Step 4
Example:
RP/0/RSP0/CPU0:router(config-if)#bfd
minimum-interval 2000
Hello interval range is 100 to 30000 milliseconds. Default
hello interval is 100 milliseconds
Configures BFD multiplier detection.
bfd multiplier number
Step 5
Example:
RP/0/RSP0/CPU0:router(config-if)#bfd multiplier
5
BFD multiplier range is 3 to 10. Default BFD multiplier
is 3.

What to Do Next
Configure BFD bring up timeout interval.
Once LSP is signaled and BFD session is created, TE allows given time for the BFD session to come up. If
BFD session fails to come up within timeout, the LSP is torn down. Hence it is required to configure BFD
bring up timeout
Configuring BFD Bring up Timeout
Perform these steps to configure BFD bring up timeout interval. The default bring up timeout interval is 60
seconds.
Before You Begin
BFD must be enabled under MPLS TE tunnel interface.
