This read-create value sets, in deciseconds, a hold-up timer that dampens how quickly a BFD Continuity Check session-up event is reported, avoiding premature 'recovered' alarms on a link that is still unstable. Admins tune it to require the link to stay up briefly before it's reported as recovered, reducing alarm flapping during a marginal recovery. It defaults to 20 deciseconds (2 seconds); a value of zero reports an up transition immediately.
