The value of tmnxVrrpPolicyDeltaInUseLimit specifies the
delta-in-use-limit for a VRRP policy. Once the total sum of
all delta events has been calculated and subtracted from the
base-priority of the virtual router, the result is compared
to the delta-in-use-limit value. If the result is less
than this value, the delta-in-use-limit value is used as the
virtual router in-use priority value. If an explicit priority
control event overrides the delta priority control events, the
delta-in-use-limit has no effect.
Setting tmnxVrrpPolicyDeltaInUseLimit to 0 and allowing the
sum of the delta priority control events to reduce the virtual
router's in-use-priority to 0, can prevented it from
becoming or staying master.
