Abstract
A bridge is devised to easily divide a spanning tree domain and to divide only a spanning tree domain while avoiding division of a broadcast domain. A spanning tree domain of a bridged LAN is divided in such a manner that a plurality of bridge protocol entities are provided in the bridge for connection between spanning trees, and ports of the bridge are assigned to the bridge protocol entities in a one-to-one relationship to enable the ports to participate respectively in different spanning trees. Spanning tree division is thus facilitated.
