Set the VRRP Group (Virtual Router) Priority

Setting a virtual router priority to 255 ensures that router is the OWNER virtual router for the VRRP
group. VRRP elects the MASTER router by choosing the router with the highest priority. The default
priority for a virtual router is 100. The higher the number, the higher the priority. If the MASTER router
fails, VRRP begins the election process to choose a new MASTER router based on the next-highest
priority.
Note: Configuring VRRP priority 255 on an interface on which DHCP Client is enabled is not supported.
If two routers in a VRRP group come up at the same time and have the same priority value, the interface's
physical IP addresses are used as tie-breakers to decide which is MASTER. The router with the higher IP
address will become MASTER.
