问题R1、R3路由表中没有pc机所在网段，但是R2路由表中却有其路由表项。（即R1和R3向R2发送路由表但是R2没有向R1和R3发送其路由表）请问该如何配置。

roy

要简明的表述问题，及环境。
把很多没有必要的部分去掉，提升帖子的可读性～

wantccie

楼主把路由器的cdp neighbor查看一下

贴上来啊，否则不知道到底接口是怎么连的。

王晓强

描述问题，本身也是一种很重要的呈现～
不然别人不容易帮到你～
也容易浪费别人的时间～
提升看贴子的效率～
从别人看的角度来发问～
同时，要注意发帖的细节，比如里面有一个错别字，标题长度过长。
对自己有要求，是成长过程中最好的催化剂。

LZ不是自己之前的问题就是这样的现象吗？
其实我很想知道LZ之前的问题是如何出现的。

回复 5 # linda.! 的帖子

谢谢 啊
是我的表述不清楚
对问题也没有看的很透彻
贸然就发帖出来   耽误大家时间了
以后我会注意改正的

你在配置OSPF的时候不是已经清除了32位主机网段，你还要怎么看主机网段
ip ospf network point-to-point
我也是看你配置文件分析的，你试试 no ip ospf network point-to-point
看看
