多点双向路由重发布潜在问题研究

Research on Potential Problems of Multi-point Bidirectional Routing Redistribution

路由重发布机制实现了不同路由域之间的路由传递,有效地解决了网络合并中路由学习的问题。单点路由器实施路由重发布简单方便,但存在着重发布路由器单点故障造成网络通信中断的隐患。事实上,在大规模网络合并的设计中,都要求部署至少2台以上的重发布路由器,使不同路由域通信枢纽具有冗余性,以保证网络通信的稳定性。分析了多点双向路由重发布技术实施过程中潜在的路由问题,并提出了常规的解决思路。

Route redistribution mechanism achieves routing transfer between different routing domains and effectively solves the problem of routing learning in network merging. It is simple and convenient for single-point router to implement route redistribution, but there is a hidden danger of network communication interruption caused by single-point failure of redistribution router. In fact, in the design of large-scale network merger, at least two or more republishing routers are required to be deployed to make communication hubs in different routing domains redundant, so as to ensure the stability of network communication. This paper analyses the potential routing problems in the implementation of multi-point bidirectional routing redistribution technology, and puts forward the conventional solutions.
