ABSTRACT:
Access routers making up a LAC device or LNS device are given virtual router functions. The virtual routers are associated with either physical interfaces or fixed logical interfaces, L2TP tunnels, or PPP sessions. This allows one LAC device or LNS device to be connected with a plurality of L2TP transfer networks or ISP networks managed by different carriers.
