Information
This command provides the flexibility to fine tune the timer values based on individual interface needs

command override timers set using the command bfd all-neighbors. Using the no form of this
command will not disable BFD if BFD is configured in CONFIGURATION mode.
Use the keyword disable to disable BFD on a specific interface while BFD is configured in from
CONFIGURATION mode.
