This section describes configuring and managing VRRP in Device Manager. The timer feature is new in release 2.1 of Device Manager. Use the Hold Down Timer to modify the behavior of the VRRP failover mechanism by allowing the router enough time to detect the OSPF or RIP routes.
The timer delays the preemption of the dominant over the subordinate, when the dominant becomes available. This timer is called the Hold Down Timer, and it has a default value of 0 seconds. Nortel Networks recommends that you set all your routers to the identical number of seconds for the Hold Down Timer.
In addition, you can manually force the preemption of the dominant over the subordinate before the delay timer expires.
