ROUTER REDUNDANCY COMMANDS

before attempting to take over as the master is three times the hello interval plus half a second

Example

Console(config-if)#vrrp 1 timers advertise 5

Console(config-if)#

vrrp preempt

Use this command to configure the router to take over as the master virtual router for a VRRP group if it has a higher priority than the current acting master router. Use the no form to disable preemption.

Syntax

vrrp group preempt [delay seconds] no vrrp group preempt

group - Identifies the VRRP group. (Range: 1-255)

seconds - The time to wait before issuing a claim to become the master. (Range: 0-120 seconds)

Default Setting

Preempt: Enabled

Delay: 0 seconds

Command Mode

Interface (VLAN)

Command Usage

If preempt is enabled, and this backup router has a priority higher than the current acting master, it will take over as the new master. However, note that if the original master (i.e., the owner of the VRRP IP address) comes back on line, it will always resume control as the master.

The delay can give additional time to receive an advertisement message from the current master before taking control. If the router attempting to become the master has just come on line, this delay also gives it time to gather information for its routing table before actually preempting the currently active router.
