配置接口IP地址和描述信息
华为：配置R1上GigabitEthernet 0/0/0接口的IP地址。使用点分十进制格式（如255.255.255.0）或根据子网掩码前缀长度配置子网掩码。interface GigabitEthernet 0/0/0ip address 10.0.13.1 24https://upload-images.jianshu.io/upload_images/24325874-52d49a1242756af8.png?imageMogr2/auto-orient/strip%7CimageView2/2/w/1240
description This interface connects to R2-G0/0/0补充命令 可以标识此接口连接的是R2

在当前接口视图下，执行display this命令查看配置结果。

从命令回显信息中可以看到，接口的物理状态与协议状态均为Up，表示对应的物理层与数据链路层均可用。 配置R2上GigabitEthernet 0/0/0接口的IP地址与描述信息。

配置完成后，通过执行ping命令测试R1和R2间的连通性。

思科：R1上面配置接口地址12.1.1.1思科的掩码如图，思科默认接口关闭，no shutdown 开启接口

R2上面配置接口地址12.1.1.2思科的掩码如图，思科默认接口关闭，no shutdown 开启接口

思科每次配置完地址记得有两条命令一定要做，方便排错R2#show ip route查看路由表R2#show ip int brief查看接口IP状态

两端ping测试联通性。！表示有路由，且有回包，U表示有路由，但是没有回包。
