RIPv2路由不是在两个串连路由器之间切换吗？
RIPv2路由不是在两个串连路由器之间切换吗？
提问于 2019-05-29 11:03:26
我刚接触过社交网络，现在已经上了6个月的课程了，所以这里可能会有一些粗俗的错误或愚蠢的答案/问题，但我却没有回答。
我有一项任务要设置RIPv2路由。在下面的图片中，您可以看到两个路由器。一个称为路由器3(底部)，另一个称为AccessRouter (顶部)。试着忽略从路由器出来的其他电缆。我特别关注在提到的两个路由器之间的串行电缆。
来自AccessRouter (top)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：
Router3
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 3‘S串行0/0/1端口之间进行ping吗?反之亦然？ping命令只会在两个路由器上产生超时。
如果你需要更多的信息，告诉我。再说一次，我仍然是个菜鸟，在这门课上我一直在努力奋斗。谢谢各位！

您没有将时钟设置在两个路由器之间链路的一端。两个interface Serial0/0/1都没有clock rate命令。这意味着您有两个DTE连接，这将无法工作。在一端设置时钟使其成为DCE，而一端必须有DCE，另一端必须有DTE。
此外，您正在通过设置静态路由来破坏访问路由器。路由器本身就知道直接连接的网络，以及如何路由到这些网络。一个直接连接的网络将有一个0的AD (最优先)，但是静态路由有一个AD的1。删除RIP下的静态路由和redistribute static。
