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.
