ip vrrp priority
This command sets the priority of a router within a VRRP group. Higher values equal higher priority. The range is from 1 to
254. The parameter <vrid> is the virtual router ID, whose range is from 1 to 255.
The router with the highest priority is elected master. If a router is configured with the address used as the address of the
virtual router, the router is called the "address owner." The priority of the address owner is always 255 so that the address
owner is always master. If the master has a priority less than 255 (it is not the address owner) and you configure the priority
of another router in the group higher than the master's priority, the router will take over as master only if preempt mode is
enabled.
Default
100 unless the router is the address owner, in which case its priority is automatically set to 255.
