Abstract
An aggregation device that connects a plurality of internal sub-networks processes a packet that is destined for one of the plurality of sub-networks. The aggregation device receives the packet and determines an internal sub-network identification value based on the combination of an external sub-network identification value that is in the packet, and a port of the aggregation device to which the one of the plurality of internal sub-networks is connected. The aggregation device may also determine an external sub-network identification value based on an internal sub-network identification value that is associated with a port of the aggregation device to which one of the plurality of internal sub-networks is connected. The external sub-network identification value is stored in the packet and the packet is transmitted on the port of the aggregation device to which the one of the plurality of internal sub-networks is connected.
