dress owner in the VRRP group; the IP address owner automatically has the highest pr
iority: 255. The priority of 0 is usually used when the IP address owner gives up the r
ole 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 r
outer, the virtual router with high priority will win. So, if there is an IP owner in the VR
RP group, it will always be the master router. For the candidate routers having the sa
me priority, selection will be done according to the magnitude of IP addresses (the bigg
er IP address takes precedence). VRRP also provides a preemptive priority policy. If su
ch policy is configured, the backup router with higher priority will preempt the role of n
ew master router over the current master router with lower priority.
In order to avoid the fault of returning a physical MAC address when Pinging virtu
al 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.
