preempt-mode

Enables or disables preempt mode for a VRRP or VRRP Extended (VRRP-E) router session.

Syntax

preempt-mode
no preempt-mode

Command Default

Enabled for VRRP; Disabled for VRRP-E.

Modes

Virtual-router-group configuration mode

Virtual-router-extended-group configuration mode

Usage Guidelines

This command is for VRRP and VRRP-E.

For VRRP-E, the interface must be a virtual interface (Ve).

When set, the highest-priority backup router will always be the master if the owner is not available. If not set, a higher priority backup will not preempt a lower-priority master.

Enter no preempt-mode to turn off preempt mode.

Examples

To turn on preempt mode for a virtual-router-group 1 session:

device# configure terminal
device(config)# ipv6 protocol vrrp-extended 
device(config)# interface ve 10 
device(config-if-Ve-10)# ipv6 vrrp-extended-group 1
device(config-vrrp-extended-group-1)# preempt-mode
