双点双向重分布中的次优路径问题及其解决办法

摘要

Large networks wil running multiple protocols, so the routes have to redistribute. Redistribution insure the validity of the networks. In the process of the redistribution, it may generate the trouble of sub- optimal path. In order to solve this problem, we use GNS3 (Graphical Network Simulator) to build simulation network environment. By re-searching the two- way redistribution, we can analyze the effect of the administrative distance in routing selection. In this paper, we designed four solutions to correct sub- optimal.%在大型的互联网络中，会同时运行多个路由协议，为了在同一个互联网络中高效地支持多种路由选择协议，必须在这些不同的路由选择协议之间共享路由信息[1]，即进行路由的重分布。在重分布的过程中，会造成次优路径问题。利用图形化网络环境模拟器GNS3搭建网络拓扑，通过对双向双点重分布实验的研究，来分析管理距离值对于路由选择的影响。本文设计了4种方案来解决这个问题。
