See the first figure in VRRP Topology for the topology in this example. You can configure VRRP master router to send an advertisement packet at regular intervals to convey to the backup routers that the master is alive. By default, this interval is 1 second. You can configure this value in the range 1 to 255. In this example, you set the advertisement interval to 5 seconds on VLAN 2.
