Abstract
The optimum relay route is selected out of a plurality of relay routes to a server. In order to solve a multirouting problem, introduced is a multi routing system for determining a relay route on the basis of a label corresponding to a terminal of an access source and a server type of an access destination instead of using an IP address as a key to select the relay route. A VPN using L2TP is also introduced. A CE router A () maps MAC addresses of terminals () that it accommodates on the L2TP-VPN session. The session ID of the L2TP is used as the session ID of VPN, which is used as the key to select a relay route.
