EIGRP 宣告错误

昨天下午 闲的没事，突然想起了学过的CISCO 知识，心想好长时间没动手做实验了，于是就打开了Packet Tracer 模拟器，做个实验吧，温习下知识点。心想做什么呢，就随手托拽了3个路由器，心里由然而生，就做个CISCO 私有的路由协议EIGRP实验吧。就开始把线连上。拓扑在附件里。由于没有较高权限，图片上传不上去。

 

搭建好网络环境后，就开始了，在各个路由器上先配置接口IP，激活接口。IP配好后，就开始配路由协议。宣告各个网段。配好后先ping 了下,现在R1 上挨着ping ，结果ping  R3 的虚拟接口不通，查看路由表没有学到R3的虚拟接口 192.168 段。在R2 上也ping 不通，也没学到192.168 段。是宣告错误？在R3 上ping R1 的虚拟接口可以通，纳闷了，查看R1 和R3 的配置，宣告虚拟接口的时候都是那么宣告的，没看出来有什么不一样。

R1 配置如下：

R1#show running-config

也没出来那错啊

R1 上我宣告虚拟接口是这样宣告的      R3上是这样的

router eigrp 50                                              router eigrp 50
 network 172.16.0.0                                     network 172.16.0.0
 network 10.0.0.0                                         network 192.168.0.0

请教下别人吧，开始在QQ群里发言，说什么的都有。于是乎小麦大哥让我把配置给他发过去，让他看看怎么回事。停了会小麦大哥发言了，宣告错误　192.168.0.0　可是C类地址　 network 192.168.0.0  这是一个24位的C类网  它与1。0/2。0/3。0/4。0是完全不同的网络。10是A类网　要么
network 192.168.1.0
network 192.168.2.0
 network 192.168.3.0
 network 192.168.4.0

要么network 192.168.0.0 0.0.7.255

恍然大悟，这才明白。

看来基础知识没有学好，还得多下功夫学习。最后感谢群里的朋友以及小麦大哥。
