ABSTRACT:
An MPLS-VPN (MultiProtocol Label Switching-Virtual Private Network) service network of the present invention includes an interface identifying device. The Interface identifying device includes a virtual router belonging to a preselected VPN and an MPLS label operating section for stacking or removing MPLS labels on or from an IP packet received from the virtual router. The label operating section is made up of a first-stage label operating section for stacking on an IP packet received from a customer an MPLS label for transferring the packet over the network and a second-stage MPLS label operating section for executing label operation for identifying a virtual interface. The network constructs a virtual interface at each virtual router for allowing a routing protocol to operate between user sites that belong to the same VPN.
