摘　　要：为满足灵活扩展和安全可靠的建网需求,设计一种基于多协议标记(Multiprotocol Label Switching,MPLS)交换虚拟专用网(Virtual Private Network,VPN)的企业跨域组网方案。在网络设备仿真平台(enterprise Network Simulation Platform,eNSP)搭建网络结构,在设备上部署开放式最短路径优先(Open Shortest Path First,OSPF)、边界网关协议(Border Gateway Protocol,BGP)以及MPLS VPN等多种复杂协议,分析MPLS VPN技术中BGP对等体建立、VPN实例创建、MPLS标签分发与交换以及VPN私网路由跨域传递等配置过程。仿真结果表明,方案提高了网络转发效率,保障了企业私网路由传递的安全性,较好地满足了企业网络建设需求。In order to meet the requirements of flexible expansion,safe and reliable network building,a cross domain networking scheme based on Multiprotocol Label Switching(MPLS)Virtual Private Network(VPN)enterprises is designed to build a network structure on the enterprise Network Simulation Platform(eNSP)simulation platform,deploy OSPF,BGP,MPLS VPN and other complex protocols on the equipment,and analyze the configuration processes of MPLS VPN technology,such as Border Gateway Protocol(BGP)peer establishment,VPN instance creation,MPLS label distribution and switching,and VPNv4 private network routing cross domain transmission.The simulation results show that the scheme improves the network forwarding efficiency,ensures the security of enterprise private network routing,and better meets the needs of enterprise network construction.
