The switch with the lowest Bridge ID is elected as the Spanning Tree Root Bridge. Which characteristic defines this election?

Root bridge election is determined by the Bridge ID. The Bridge ID is a combination of a Bridge Priority and the switch’s MAC address. Switches compare these IDs to pick the Root Bridge: the lowest Bridge ID wins. Priority is the primary factor, and if two switches share the same priority, the MAC address is used as a tiebreaker, with the lower MAC winning. Therefore, the switch with the smallest Bridge ID becomes the Root Bridge. IP addresses and port numbers aren’t used in this election, and the Bridge ID is the single factor that governs which switch takes the root role. The Bridge ID is usually written as priority.MAC, with a default priority that can be adjusted to influence root selection.
