STP convergence
In spanning-tree terminology, the process of detecting redundant links and
calculating a preferred network path is called convergence.
The first step in the convergence process is to elect a root bridge, which serves as the
central point (or root) of the STP network. The root bridge is also responsible for
notifying other switches of any STP changes.
To elect the root bridge, the switches exchange BPDUs, which contain information
such as each switch's bridge ID. The switch with the lowest bridge ID is elected root
bridge.
The bridge ID has two parts:
 A user-configurable priority value
 The device's MAC address
