Router priority in a VRRP group
VRRP determines the role (master or backup) of each router in a VRRP group by priority. A router with higher priority is more likely to become the master.
A VRRP priority can be in the range of 0 to 255, and a greater number represents a higher priority. Priorities 1 to 254 are configurable. Priority 0 is reserved for special uses, and priority 255 is for the IP address owner. The IP address owner in a VRRP group always has a running priority of 255 and acts as the master as long as it operates correctly.
