of the virtual router interface, then the virtual router will be called the IP address owner in
the VRRP group; the IP address owner automatically has the highest priority: 255. The
priority of 0 is usually used when the IP address owner gives up the role of master. The
range of priority can be configured is 1-254. The configuration rule of priority can be set
according to the speed and cost of the link, the performance and reliability of the router
and other management policies. In the selection of the master router, the virtual router
with high priority will win. So, if there is an IP owner in the VRRP group, it will always be
the master router. For the candidate routers having the same priority, selection will be
done according to the magnitude of IP addresses (the bigger IP address takes
precedence). VRRP also provides a preemptive priority policy. If such policy is configured,
the backup router with higher priority will preempt the role of new master router over the
current master router with lower priority.
In order to avoid the fault of returning a physical MAC address when Pinging virtual IP,
it is regulated that virtual IP can not be the real IP of the interface. Thus, all the interfaces
participating of the backup group selection will be backup by default.
