网络工程 - RIPv2 路由在两个串行连接的路由器之间没有 ping 通？ - 吾爱随笔录

我是网络新手，目前正在学习 6 个月的课程，所以这里可能会有一些新手错误或非常愚蠢的答案/问题，但对我来说是裸露的。

我的任务是设置 RIPv2 路由。在下图中，您可以看到两个路由器。一个称为Router 3（底部），另一个称为AccessRouter（顶部）。尝试忽略从路由器出来的其他电缆。我特别关注在提到的 2 个路由器之间连接的串行电缆。

AccessRouter（顶部）的 Se0/0/1 接口的 IP 地址为 172.30.150.225。来自 Router3（底部）的 Se0/0/1 接口的 IP 地址为 172.30.150.226。我的路由在我的运行配置中为每个设备配置如下：

路由器3

router rip
version 2
 network 172.30.0.0
 no auto-summary
!
ip classless

接入路由器

router rip
 version 2
 redistribute static 
 network 172.30.0.0
 no auto-summary
!
ip classless

现在我已经配置了 RIP 路由，难道我不能在 AccessRouter 和 Router3 的serial0/0/1端口之间 ping 通吗？反之亦然？ping 命令只会在两个路由器上产生超时。

如果您需要更多信息，请告诉我。再说一次，我还是个菜鸟，在这门课上有点挣扎。多谢你们！
