on the router by making them less restrictive and increasing the survival chances
for the session.
NOTE: Enabling BFD adaptive timers targets only rapidly flapping events and not
genuine BFD down events. If BFD down events occur in intervals longer than 5
seconds, the session does not attempt to adapt.
Disabling BFD adaptive timers does not affect current adaptive timer intervals for
sessions. Disabling adaptive timers prohibits BFD from further adapting timer intervals
for existing sessions or for new sessions.
To reset adapted intervals for all BFD sessions on the router, use the clear bfd
adapted-intervals command.
bfd adapt

Clearing BFD Sessions
You can use the clear bfd session or clear ipv6 bfd session commands to clear one
or more BFD sessions for IPv4 or IPv6 (respectively).
clear bfd session
Use to enable all BFD sessions to adapt timer intervals on all virtual routers on
the router.
Example
host1(config)#bfd adapt
Use the no version to disable subsequent BFD sessions from adapting timer
intervals without resetting any already adapted intervals.
See bfd adapt.
Use to reset adapted timer intervals for all BFD sessions on the router.
Does not disable the state of the BFD adaptive timer interval feature.
Example
host1#clear bfd adapted-intervals
There is no no version.
See clear bfd adapted-intervals.
Use to restart all IPv4 BFD sessions or a specified IPv4 BFD session.
Use the address keyword to indicate the IPv4 address of the destination to which
the session has been established.
