当ping到OSPF多播地址不能工作时，该怎么办？

Question

我正在添加一个新的路由器到OSPF设置。配置似乎一切正常，但状态仍然是INIT/DROTHER。当我从新路由器进行ping到224.0.0.5时，我得到的结果是：

CB# ping 224.0.0.5

键入转义序列以中止。将1100字节的ICMP Echos发送到224.0.0.5，超时为2秒：.CB#

在另一个路由器上使用同一个地址的ping是很好的。

请指点。

Answer 1

路由器需要在启动后重新循环电源，一切都开始正常工作。

Answer 2

首先，我会在同一个网段(在本例中为10.10.1.1和10.10.1.2)上平其他设备，以查看是否有任何响应。如果您有基本的L3连接，那么我将开始查看OSPF事件调试或OSPF数据包调试。

不过，我不会依赖OSPF组播IP的任何ping响应。

编辑:啊，您已经在其中一个路由器上显式地配置了各种OSPF间隔。这些在所有路由器上都是匹配的，形成一个邻接，所以当发送Hello数据包时，它们会立即作为无效丢弃。
