Changing the Advertisement Interval
By default, the MASTER router transmits a VRRP advertisement to all members of the VRRP group every
one second, indicating it is operational and is the MASTER router.
If the VRRP group misses three consecutive advertisements, the election process begins and the BACKUP
virtual router with the highest priority transitions to MASTER.
NOTE: To avoid throttling VRRP advertisement packets, Dell Networking OS recommends
increasing the VRRP advertisement interval to a value higher than the default value of one second. If
you do change the time interval between VRRP advertisements on one router, change it on all
participating routers.
To change the advertisement interval, use the following command.
• Change the advertisement interval setting.
INTERFACE-VRID mode
advertise-interval seconds
The range is from 1 to 255 seconds.
The default is 1 second.
