The root switch is the switch with the lowest numeric value for the bridge ID. Because the two-part bridge ID starts with the priority value, essentially the switch with the lowest priority becomes the
root. For example, if one switch has priority 100, and another switch has priority 200, the
switch with priority 100 wins, regardless of what MAC address was used to create the
bridge ID for each bridge/switch.
If priorities are equal then the switch with the lowest numerical value of MAC address wins.
