Usage
Information
This command provides the flexibility to fine tune the timer values based on individual interface
needs when ISIS BFD is configured in CONFIGURATION mode. Any timer values specified with
this command override timers set using the bfd all-neighbors command. Using the no

Use the keyword disable to disable BFD on a specific interface while BFD is configured in
CONFIGURATION mode.
