EIGRP -邻居建立过程

Question

每个路由器都是用EIGRP实现的，共享其路由。

作品：

ISP，R1，R2，R4

问题：

R3不能与R1建立邻居关系，其路由也不能共享。

和其他路由器一样，我也是这么做的。

R3 -

R3#ping 10.0.0.13

Type escape sequence to abort.
Sending 5, 100-byte ICMP Echos to 10.0.0.13, timeout is 2 seconds:

R1 -

我认为是auto-summary的残疾，但事实并非如此。有什么建议吗？

Answer 1

将有助于查看R1和R3的EIGRP配置，这些配置可以与show run | section router eigrp 1或仅用show run显示，并从“路由器eigrp 1”复制该部分。

这么说，我看上去你输入了错误的网络声明。在R1上，您可以看到：

Routing for Networks:  
  10.0.0.4/30
  10.0.0.0/30
  10.0.0.8/30
  1.0.0.12/30

应该是10.0.12/30，而不是1.0.0.12/30。

在路由器eigrp 1下的R1上，您应该输入network 10.0.0.12 0.0.0.3并删除任何其他网络语句。

删除任何其他网络语句的原因是，除了串行链接之外，我看不到任何其他直接连接的网络，而且您也没有提到任何回环等等。“Networkx.xY.Y”语句告诉EIGRP它应该启用EIGRP的哪些接口，并为该网络做广告。
