摘　　要：BGP MPLS VPN网络架构是一种由MP-BGP技术和MPLS技术相结合的新型VPN网络架构。为了提高BGP MPLS VPN网络架构中接入层PE的可靠性,通常部署CE双归属架构,然而该方案在特殊组网下,可能会存在次优路径。详细分析了一种基于CE双归属的特殊组网场景,针对存在的问题部署了OSPF虚连接优化方案,并使用ENSP软件进行模拟仿真,验证该方案的可行性。BGP MPLS VPN network architecture is a new VPN network architecture combined by MP-BGP technology and MPLS technology.In order to improve the reliability of access layer PE in BGP MPLS VPN network architecture,the common solution is to deploy CE dual attribution architecture.However,this scheme may have suboptimal paths under special networking.It analyzes a special networking scenario based on a CE dual attribution,deploys OSPF virtual connection optimization scheme for the existing problems,and uses ENSP software to verify the feasibility of the optimization scheme.
