EIGRP邻居拍打

Question

我在GNS3中设置了一个EIGRP拓扑。看起来是这样的：

R7和R8之间的邻居关系一直在摇摆，我不知道为什么。Hello和时间延迟都已被正确设置。我想这一定是我的配置。我还嗅探了wireshark中的网络流量，它充斥着来自R7的ICMP超过了发送给R8的数据包。

我对其进行了如下测试：

• 只打开R1-R6 = EIGRP路由，工作正常
• 只打开R7-R9 = EIGRP路由，工作正常
• 打开所有路由器=邻居拍打，网络充斥ICMP数据包

以下是我的心声：

我相信这一定是配置错误，但我找不到它。任何帮助都将不胜感激。

Answer 1

经过几个小时的测试。这个问题被发现是一个损坏的IOS图像。我用一个更旧的版本交换了这张照片，我所有最初的吐露都在正常工作。哈！

Answer 2

您正在两个网络部分中运行一个不连续的类网络172.16.0.0 / 16。在这种特殊情况下，自动摘要将使您的路由表不一致，通过总结上面的网络，并将其广告到另一边，反之亦然。

尝试在所有路由器上不向您的eigrp设置添加自动摘要，以便最终的配置如下：

    router eigrp 1
     no auto-summary
     network x.x.x.x
