摘要
文章系统地分析了MCE双归属网络结构中存在的OSPF路由域分割、次优路径和路由环路等问题.结合典型案例,在MPLS VPN网络作为OSPF超级骨干域的基础上,采用Sham-Link解决次优路径问题,通过DN置位或Route-tag标识的方法避免路由环路的产生.文章通过协议路由和OSPF LSA的分析方法定位网络的潜在风险,结合具体案例暴露问题,针对不同的问题提出了具体可行的技术方案,并对相关技术的实施要点和注意事项进行了说明,为MPLS VPN网络的优化提供技术支持.
Abstract
The paper systematically analyzes the problems existing in the MCE dual attribution network structure,such as OSPF routing domain separation,suboptimal path and routing loop.Combined with typical cases,based on the MPLS VPN network as OSPF super backbone domain,it uses the Sham-Link to solve the suboptimal path problem,and avoids the generation of routing loops by means of DN bit or Route-tag.This paper analyzes protocol routing and OSPF LSA to locate the potential risk of network,and exposes the problems with specific cases.It proposes specific and feasible technical solutions for the different problems,and explains the implementation key points and the matters needing attention of the relevant technologies.It also provides technical support for the optimization of MPLS VPN network.
