The role of the active and standby routers is determined during the HSRP election process
By default, the router with the numerically highest IPv4 address is elected as the active router
To configure a router to be the active router, use the standby priority interface command
If the priorities are equal, the router with the numerically highest IPv4 address is elected as the active router
The range of the HSRP priority is 0 to 255
