网络问题
提问于 2015-05-25 08:57:23
我的关系网出了问题。我有一个路由器( R1 )连接到另一个路由器(R2)，R1连接到交换机。R1交换机有两台PC与其相连。PC IP分别为128.107.35.10和192.31.7.10。默认网关为198.133.220.1。当我从R1 PC上点击时，请求超时。当我从R2个人电脑上点击时，我得到了无法到达的目标主机。我在两个路由器上都有OSPF和RIP v2。有人知道为什么会这样吗？

这里的信息不多，但这是.
您不能让IP地址为128.107.33.10的PC和IP地址为192.31.7.10的PC使用198.133.220.1/27的默认网关。大多数操作系统会抱怨默认网关与PC不在同一网络中，但我对您的PC上的网络掩码一无所知。您有两个简单的选项(不更改R2上的配置或使用包含两台PC的大规模子网掩码)：
备选案文1：
如果你一定要在电脑上保留相同的IP地址.您可以将FastEthernet 1接口上的主IP地址更改为与第一台PC位于同一网络中，并向FastEthernet 1中添加一个辅助IP地址，以匹配在第二台PC上定义的网络。然后，您需要将这些网络添加到RIP和/或OSPF中，以便将它们分发给R2 (如果两者都使用，则OSPF路由将显示出来，RIP路由将被忽略，但这仍然可以)。
备选案文2：
你把个人电脑改为198.133.220.2到198.133.220.14之间的网络掩码255.255.255.224。您还需要向RIP和/或OSPF添加一个网络语句来为198.133.220.0/27网络做广告。
您还最好更改连接在R1和R2之间的串行接口，使双方位于同一个子网中(尽管如此，神奇的PPP可能会使这一工作变得更好，但不推荐它，跟踪器看起来也会很奇怪)。我也不会运行两个路由协议，没有真正的理由，我会整理整件事情(它需要一个网络重新设计！)，但我假设有很好的理由这样做。

你的路由器上没有接口？它们应该出现在节目中运行或写入术语输出。在任何情况下，都需要在静态路由中启用路由协议或代码。这是一个路由问题。我没有看到在您的输出中配置了RIP。如果愿意，请配置RIPv2。文件在线。
