ABSTRACT:
A switch is provided for use in a virtual communications system having multiple local area networks interconnected by multiple switches through a trunk, which has one or more trunk stations connected directly thereto. The switch includes a first communications port connected directly to a first local area network and a second communications port connected directly to the trunk. The first local area network is within a virtual area network configured to include a second local area network and a trunk station. A switch control detects a communication from the first local area network having a multicast address representing desired destination addresses. The switch control appends a VLAN header having a destination address different than but corresponding to the multicast address to the communication to form a VLAN communication and directs transmission of the VLAN communication to the second communication port for delivery to the multicast addressees.
