| 1. A method comprising:
receiving a packet on an Ethernet port of a network device, wherein the packet includes Ethernet tagging information and a
subscriber information string;
dynamically building within the network device a primary virtual local area network (VLAN) sub-interface (PVS) based on the
Ethernet tagging information;
dynamically building within the network device a subscriber VLAN sub-interface (SVS) based on the subscriber information string;
determining that the packet conforms with the Dynamic Host Configuration Protocol (DHCP);
dynamically building a first Internet Protocol (IP) interface over the PVS within the network device based on the determination
that the packet conforms with the DHCP; and
dynamically building a second IP interface over the SVS within the network device based on the determination that the packet
conforms with the DHCP.
