advertise-backup

Enables a backup VRRP router to send advertisement frames to the master VRRP router.

Syntax

advertise-backup
no advertise-backup

Command Default

Advertisement is disabled.

Modes

Virtual-router-group configuration mode

Usage Guidelines

Advertisement packets (or frames) are sent to all members of a VRRP group to indicate that the master router is operational. When the master router is not operational, the backup router becomes the master router. When you run this command, the backup router sends the frames every 60 seconds.

Use this command for VRRP-E, but not for VRRP.

Enter no advertise backup to return to the default setting (no periodic transmission).
