www.dell.com | support.dell.com Change the Advertisement interval By default, the MASTER router transmits a VRRP advertisement to all members of the VRRP group every 1 second, indicating it is operational and is the MASTER router. If the VRRP group misses 3 consecutive advertisements, then the election process begins and the BACKUP virtual router with the highest priority transitions to MASTER. Note: Dell Force10 recommends you to increase the VRRP advertisement interval to a value higher than the default value of 1 second to avoid throttling VRRP advertisement packets. If you do change the time interval between VRRP advertisements on one router, you must change it on all participating routers. Change that advertisement interval with the following command in the VRRP mode: Task Change the advertisement interval setting.
