一、实验拓扑

二、实验需求

1、R1、R2、R3都是各自网络的网关设备
2、本实验采用LoopBack接口模拟客户端
3、通过静态路由来实现这些网络之间的互联互通
4、R1-R2为主路径，R1-R3-R2为备用路径

三、实验配置

1、设备命名

[Huawei]sysname  R1
[Huawei]sysname  R2
[Huawei]sysname  R3

2、配置各自接口地址

[R1-GigabitEthernet0/0/1]ip address 10.0.13.1 24
[R1-GigabitEthernet0/0/3]ip address 10.0.12.1 24
[R1-LoopBack0]ip address 10.0.1.1 32
[R2-GigabitEthernet0/0/3]ip address 10.0.12.2 24
[R2-GigabitEthernet0/0/2]ip address 10.0.23.2 24
[R2-LoopBack0]ip address  10.0.1.2 32
[R3-GigabitEthernet0/0/1]ip address 10.0.13.3 24
[R3-GigabitEthernet0/0/2]ip address 10.0.23.3 24
