  • receiving a packet from an access network, the packet having a first Virtual Local Area Network (VLAN) tag of a first predetermined bit length; and

    mapping the service instance identifier of the first VLAN tag into a second VLAN tag of a second predetermined bit length greater than the first predetermined bit length, the second VLAN tag identifying a Virtual Private LAN Service (VPLS) instance;

    sending the packet with the second VLAN tag across a service provider (SP) core network via a pseudowire (PW) that functions as a logical link to another PE device.
