一、实验拓扑

IPv4编址及IPv4路由基础实验拓扑

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 [R3-LoopBack0]ip address 10.0.1.3 32
