摘　　要：面向电信业务发展现状,探讨了一种满足客户新需求的应用模式。通过图文结合的方式,描述了L2TP VPDN与BGP/MPLS IP VPN的工作原理,包括相关概念、典型拓扑结构及组件。在此基础上,提出了结合L2TP VPDN与BGP/MPLS VPN两者优势,L2TP VPDN LNS设备兼作BGP/MPLS VPN PE设备的解决思路,给出了L2TP VPDN MPLS混合型组网拓扑,并简述了其应用优势。With the development situation of telecom VPN business,a VPN application model is explored,thus to meet the new requirements by customers.The operational principles of L2TP VPDN and BGP/MPLS IP VPN are described,including their related concepts,typical topologies,and components.Based on this,a solution for hybrid-mode VPN in combining the superiorities of both L2TP VPDN and BGP/MPLS IP VPN is proposed,in which L2TP VPDN LNS also serves as BGP/MPLS VPN PE.And the application advantages of the Hybrid-mode VPN are also given in this paper.
