preempt delay minimum

Syntax

preempt delay minimum <DELAY-IN-SECONDS>

no preempt delay minimum <DELAY-IN-SECONDS>

Description

Sets the time in seconds (1-3600) that the router will wait before taking control of the virtual IP and starting to route packets.

The no form of this command sets the preempt delay for the VRRP group to the default preempt delay of 0 seconds.

The VRRP Preempt Delay Timer (PDT) allows admin users to configure a period of time before the VR takes control of the virtual IP address. It does not transition to the Master state until the timer period expires.

The timer value configured should be long enough to allow upper layer protocol to converge. The PDT is applied only during initialization of the router.
