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
overrides timers set using the bfd all-neighbors command. Using the no form of this command
does not disable BFD if BFD is configured in CONFIGURATION mode.
To disable BFD on a specific interface while BFD is configured in CONFIGURATION mode, use the
keyword disable.
