Abstract
A network system is provided. The network system includes a first network device and a second network device running in data link layer (L2). The first network device includes a first switch and a first PPPoE (Point-to-Point over Ethernet) agent integrally coupled to the first switch. The second network device also includes a second switch and a second PPPoE agent integrally coupled to the second switch. The network system further includes a PPPoE client running in network layer (L3) that communicates to the first PPPoE agent and a PPPoE server in L3 that communicates to the second PPPoE agent. The PPPoE client uses a broadcast (Bcast) MAC address in an initial IPCP (Internet Protocol Control Protocol) negotiation message between the PPPoE client and the PPPoE server.
