Question

Quizplus · Accepted Answer

STP selects the root bridge based on the lowest Bridge ID (BID) number. The Bridge ID is made up of a priority value and the MAC address of the switch. The root bridge is the switch with the lowest BID, and all other switches must choose the path that leads to the root bridge when calculating their spanning tree. Port number, bridge version number, and software revision code are not factors in selecting the root bridge.
