ABSTRACT:
Techniques are described that allow a network device, such as a router, to forward data packets received from a subscriber device to an Ethernet virtual local area network (VLAN) interface within the network device where the VLAN interface has been dynamically built based on a subscriber information string. For example, a primary VLAN sub-interface (PVS) and a subscriber VLAN sub-interface (SVS) may each be dynamically built over a statically built VLAN major interface. In particular, the network device comprises a forwarding controller, where the forwarding controller receives a data packet over an Ethernet port. The network device accesses upper-layer protocol information within the data packet to determine an SVS within the network device to which to forward the data packet based on the upper-layer protocol information.
