路由反射技术应用于MPLS VPN的研究

Application of the Technology of Route Reflection in the Network of MPLS VPN

简要介绍了MPLS VPN和BGP路由协议的基础知识以及两者之间的关系,分析了路由反射技术的基本原理,提出采用路由反射技术来提高MPLS VPN的可靠性和减少I-BGP逻辑连接的复杂性。较为详细地探讨了在MPLS VPN网络中不使用路由反射机制的方案和使用路由反射机制的方案,针对路由反射技术在实际案例中的应用,给出了较为详细的设计,并对两种方案的优缺点进行了分析比较。

This article briefly introduces the basic knowledge of MPLS VPN and BGP routing protocol and the relationship between them, analyses the basic principle of the technology of Route Reflection and suggests that the technology of Route Reflection is a solution to improving the reliability of MPLS VPN and lessening the complexity of the logical connections of I-BGP, It introduces one solution without RR and the other one with RR applied in MPLS VPN in detail. In addition, it provides a real case with a comparatively detailed design using the technology of Route Reflection, Finally, it compares the solution without RR with the one with RR.
