Enable IPv4 VRRP Preempt Mode
You can configure VRRP to preempt the existing router. If a new VRRP router is added to the network with a higher priority than the existing routers, then the new router becomes the master. If preempt-mode is disabled, then the new router does not become a master, it transitions to master only when the current master is down, that is when it does not receive any advertisement packets from the current master. By default, preempt-mode is enabled.
