The value of vRtrMplsTpOamTmplHoldTimeDown specifies the time, in
centiseconds, used for the hold-timer for the BFD Continuity Check (CC)
session down event dampening. This guards against reporting excessive
operational state transitions.
This is implemented by not advertising subsequent transitions of the
BFD CC state until the configured timer has expired.
A value of zero (0) specifies that a down transition is reported
immediately.
