本次實驗，路由器，思科的網絡設備
拓撲如下（比較簡單）：

首先是動態路由協議配置及ip配置

netw 192.168.34.0

ip 地址配置：2.2.2.2是R2 4.4.4.4是R4
主要查看3和1路由器中路由表的變化

接下來是重發布，首先將AD值小的ospf重發布到AD值大的RIP中去
====================================ospf-rip

------------------3
en
conf t

====================================
其次將rip重發布到ospf中去
=====================================rip-ospf

---------------------1
en
conf t

red rip subn
end

雙點雙向重分發與次優路徑問題

在雙點雙向重分發中，經常會遇到次優路徑問題，所謂次優路徑就是由於路由協議的重分發，導致並不是最優的路由替代了現有的最優路由，根本原因就是重分發過來的路由的管理距離比現有的路由管理距離要小，進而替代了現有的最優路由，這就是次優路徑問題。 我們直接用下面拓撲圖作為例項來演示一下次優路徑問

RIP是一種分散式的基於距離向量的路由選擇協議， OSPF是一種分散式的基於鏈路狀態的路由選擇協議 RIP：僅於相鄰的路由器交換狀態；路由器交換的資訊是當前本路由器所知道的全部資訊，即路由表；按固定的時間間隔交換路由資訊 OSPF：向本自治系統所有的路由器傳送資訊；傳送的
