See the first figure in VRRP Topology for the toplology in this example. You can configure VRRP to preempt the existing router. This means that if a new VRRP router is added to the network with priority higher than the existing routers, then the new router becomes the master. If preemption is disabled, then the new router will not become a master. This router becomes master only when the current master is down, that is, only when it does not receive any advertisement packets from the current master. By default, preempt mode is enabled.
