Figure 40.2. VRRP Group Example
Other VRRP parameters are the Advertisement Interval and Gratuitous ARP Delay.
The advertisement interval is the time between which advertisements are sent. A backup router will
assume mastership four advertisement intervals after the master fails, so the minimum fail-over time is
four seconds. If a monitored interface goes down, a master router will immediately signal an election
and allow a backup router to assume mastership.
The router issues a set of gratuitous ARPs when moving between master and backup state. These
unsolicited ARPs teach the hosts and switches in the network of the current MAC address and port
associated with the VRIP. The router will issue a second set of ARPs after the time specified by the
Gratuitous ARP delay.
