advertise backup

Advertises a Virtual Router Redundancy Protocol (VRRP) backup router to a VRRP master router.
Syntax
advertise backup
no advertise backup
Command Default

A VRRP backup router does not advertise itself to a VRRP master router.

Modes

VRID interface configuration mode

Usage Guidelines

Hello messages are used to advertise a backup router to a master router. To configure the interval at which the messages are sent, use the backup-hello-interval command.

The advertise backup command is configured only on VRRP backup routers and is supported by VRRP and VRRP-E.

The no form of the command disables the advertisement of a VRRP backup router to a VRRP master router.

Examples

The following example enables advertisements from the VRRP backup router and configures the hello message interval to 10 seconds.

device# configure terminal
device(config)# router vrrp
device(config)# interface ethernet 1/1/6
device(config-if-e1000-1/1/6)# ip address 10.53.5.1/24
device(config-if-e1000-1/1/6)# ip vrrp vrid 1
device(config-if-e1000-1/1/6-vrid-1)# advertise backup
device(config-if-e1000-1/1/6-vrid-1)# backup-hello-interval 10
