摘要： 分析工程应用中3种服务商边缘-客户边缘互连技术，在OPNET14.5平台上搭建相应的仿真网络环境，研究边界网关协议和多协议标记切换虚拟专用网的网络性能。阐述该环境下路由会聚的一般过程，分析3种互连技术的会聚时间，讨论软件仿真与实际网络存在差异的主要原因。仿真结果表明，静态路由的IP路由收敛速度最快，外部边界网关协议次之，开放最短路径优先协议的收敛速度最慢.

Abstract: This paper analyzes three kinds of Provider Edge(PE)-Client Edge(CE) connection technologies in the application of projects and builds the corresponding simulation network environment based on OPNET14.5 platform. It makes research on the performance of the Border Gateway Protocol(BGP)/Multi-Protocol Label Switching Virtual Private Networks(MPLS VPN). It analyzes the common process of route convergence in this environment and the corresponding convergence time for three kinds of different connection technologies. Simulation results show that the IP convergence duration of static route is less than that of external BGP and the convergence duration of Open Shortest Path First(OSPF) protocol is longest.

Key words: network convergence, route re-distribution, Provider Edge(PE), Client Edge(CE)
