after expounding the concepts of MPLS VPN and BGP, the advantage of MPLS VPN is described, subsequently a computer network experiment based on MPLS VPN and BGP is designed. The experiment includes three parts: network topology design, IP address planning and configuration implementation. First, the experiment is simulated through the simulator, and then the network is constructed with real physical equipment. After the experiment, the corresponding evaluation can be obtained immediately, and all network parameters are tested normally. Through the completion of this experiment, the teaching has achieved good results.
