Spanning Tree Protocol
Page 7-3
The Root Bridge is a central point from which the network is
configured. It is selected on the basis of having the lowest
Bridge Identifier value. This is a combination of the bridge’s
unique MAC address and a priority component defined for the
bridge.
The Root Bridge generates BPDUs on all ports at a regular
interval known as the Hello Time. All other bridges in the
network have a Root Port. This is the port nearest to the Root
Bridge, and it is used for receiving the BPDUs initiated by the
Root Bridge.
