preempt

Parameters

vlan vlan‐id	Specifies the number of the VLAN on which to configure the VRRP
	advertisement interval. This VLAN must be configured for IP routing as
	described in “Pre‐Routing Configuration Tasks ” on page 18‐1.

vrid	Specifies a unique Virtual Router ID (VRID) associated with the routing
	interface. Valid values are from 1 to 255.

interval	Specifies a VRRP advertisement interval to associate with the vrid. Valid
	values are from 1 to 255 seconds.

Defaults

None.

Mode

Router configuration: C3(su)‐>router(Config‐router)#

Usage

VRRP advertisements are sent by the master router to other routers participating in the VRRP master selection process, informing them of its configured values. Once the master is selected, then advertisements are sent every advertising interval to let other VRRP routers in this VLAN/ VRID know the router is still acting as master of the VLAN/VRID.

All routers with the same VRID should be configured with the same advertisement interval.

Example

This example shows how set an advertise interval of 3 seconds on the VLAN 1 interface, VRID 1:

C3(su)->router(Config)#router vrrp

C3(su)->router(Config-router)#advertise-interval vlan 1 1 3

preempt

Use this command to enable or disable preempt mode on a VRRP router. The no form of this command disables preempt mode.

Syntax

preempt vlan-id vrid

no preempt vlan-id vrid

Parameters

vlan vlan‐id	Specifies the number of the VLAN on which to set preempt mode. This
	VLAN must be configured for IP routing as described in “Pre‐Routing
	Configuration Tasks” on page 18‐1.

vrid	Specifies a unique Virtual Router ID (VRID) associated with the routing
	interface. Valid values are from 1 to 255.

Defaults

None.
