我正在向 OSPF 设置中添加一个新路由器。配置似乎一切正常,但状态仍为 INIT/DROTHER。当我从新路由器 ping 224.0.0.5 时,我得到的是:
CB# ping 224.0.0.5
键入中止的转义序列。向 224.0.0.5 发送 1 个 100 字节 ICMP 回显,超时为 2 秒:。CB#
在另一个路由器上对同一地址进行 ping 操作,工作正常。
请指教。

答案1
首先,我会 ping 同一网段上的其他设备(本例中为 10.10.1.1 和 10.10.1.2),看看是否有任何响应。如果您有基本的 L3 连接,我会开始查看 OSPF 事件调试或 OSPF 数据包调试。
不过,我不会依赖来自 OSPF 多播 IP 的任何 ping 响应。
编辑: 啊,您已在其中一个路由器上明确配置了各种 OSPF 间隔。这些间隔必须与形成邻接关系的所有路由器匹配,因此当发送 Hello 数据包时,它们会立即被视为无效而丢弃。
答案2
路由器启动后需要重新通电才能正常工作。
