Usage
Information
This command provides the flexibility to fine-tune the timer values based on individual interface
needs when you configure ipv6 ospf BFD 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 you configure BFD in CONFIGURATION
mode.
To disable BFD on a specific interface while you configure BFD in CONFIGURATION mode, use
the keyword disable.
