Configuring the PDT

The VRRP PDT allows you to configure a period of time before the VR takes control of the VIP. It does not transition to the master state until the timer period expires. The timer value configured should be long enough to allow OSPF convergence following OSPF updates.

The PDT is applied only during initialization of the router, that is, when the router is rebooting with the VRRP parameters present in the startup config file.
