Abstract
A local system including at least two VLANs may be connected to a local layer 2 switch to a wider network by providing a connection between the local switch and a router port and a single logical layer 3 interface may be assigned to the VLANs. A VLAN tag may be assigned to each connected VLAN. Outgoing data including the user's address, the intended recipient of the data and the VLAN tag assigned to the VLAN may be communicated to the router. The address of the user and the VLAN tag may be copied to a forwarding table, and the outgoing data may be forwarded to the wider network for delivery to the intended recipient. Incoming date intended for delivery to the user may be received at the assigned layer 3 interface and forwarded to the local switch for delivery to the user.
