在这种情况下，我如何使它走浮动路线而不是主要静态路线？

Question

在这个拓扑中，我已经用这样的方式配置了设备：

当我从PC1切换到PC2时，从PC1到PC2的路径如下：

但是返回，从PC2到PC1的方式如下：(导致数据包被丢弃)

问题：

如何使返回路由，即从PC2到PC1的返回路由如下所示，即，虽然通过上静态路由的路径是活动的，但它经过较低的浮动静态路由？

数据包跟踪器文件如下：https://www.mediafire.com/file/3dvgy683vestflg/Static_Routes.pkt/file

Answer 1

R4以错误的方式将其发送到R2，因此您需要获得路由器4将其发送到R3，这是您需要修复的R4中的两行

ip route 192.168.1.0 255.255.255.0 10.1.1.9 
ip route 192.168.1.0 255.255.255.0 10.1.1.13 5

使R3的度量具有更高的优先级，更低的度量--我倾向于在所有相关的路由上使用度量，所以很明显，我考虑了它--将上面的行替换为

ip route 192.168.1.0 255.255.255.0 10.1.1.9 10
ip route 192.168.1.0 255.255.255.0 10.1.1.13 5
