实验要求:为两个路由器之间配置浮动路由，两台主机互通

[Huawei]ip route-static 192.168.1.0 24 192.168.2.1 preference 60
Info: Succeeded in modifying route.
[Huawei]ip route-static 192.168.1.0 24 192.168.3.1 preference 80
Info: Succeeded in modifying route.
验证:在AR9和AR10的命令行输入display routing-table
AR9如图所示：
AR10如图所示：
现在我们看到的路由是主路由，两台主机也能互通
现在我们更改优先级，使用备用路由互通
