ABSTRACT:
Methods and apparatus for selecting a parallel bridge number for a bridge connecting a first and second LAN in a network comprised of LANs and bridges connected between the LANs. The parallel bridge numbers are used to distinguish two or more bridges which are connected between the same LANs. The designated bridge for the LAN stores a database associating the identifiers of multiple bridges connected between the first and second LANs to the parallel bridge numbers which are assigned to those bridges. To obtain a parallel bridge number, a bridge between the first and second LANs transmits a request message identifying itself and the second LAN to the designated bridge. In response, the designated bridge selects a parallel bridge number which has not been associated with any bridge connected to the second LAN (other than the requesting bridge), and transmits this parallel bridge number to the requesting bridge.
