Configuring VRRP advertise-interval

21-66 Routing Protocol Configuration

advertise-interval

UsethiscommandtosettheintervalinsecondsbetweenVRRPadvertisements.

Syntax

advertise-interval vlan vlan-id vrid interval

no advertise-interval vlan vlan-id vrid interval

Parameters

Defaults

None.

Mode

Routercommand,Routerconfiguration:Matrix>Router(config‐router)#

Usage

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

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.

The“no”formofthiscommandclearstheVRRPadvertiseintervalvalue.

Example

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

Matrix>Router(config)#router vrrp

Matrix>Router(config-router)#advertise-interval vlan 1 1 3

critical-ip

UsethiscommandtosetacriticalIPaddressforVRRProuting.

Syntax
