Research on Virtual Router and Its Application in BGP/MPLS VPN

【Abstract】Based on the research of virtual router and MPLS, this paper designs and implements a virtual router that supports MPLS, moreover, it makes studies on the application of virtual router in the experimental system of BGP/MPLS VPN. Also, the paper presents an effective solution for the system that enables each user to configure and operate independently, provides all the users a common topology of the network and consume relatively fewer software resources as well, effectively addresses the problem brought by the simultaneous operation of a large number of people.
