The last command to consider is the priority command. This command is used to determine the designated and backup designated routers on a multiaccess link. Remember that the Hello protocol is the mechanism by which the designated routers are elected. To be "up for election," the priority must be a positive integer between 1 and 255. If the priority is 0, the router cannot participate in the election. The higher the priority, the greater the likelihood of being elected. If no priority is set, all Cisco routers have a default priority of 1, and the router ID is used as a tiebreaker. In effect, this means that the router ID is the determining factor.
