实验一. 路由器IP地址配置及直连网络
实验目的
理解IP地址掌握路由器端口IP 地址的配置方法理解路由器的直连网络实验步骤
布置拓扑，通过GigabitEthernet0/0/0端口连接192.168.1.0/24（手动改），通过GigabitEthernet0/0/1端口连接192.168.2.0/24（指令改）
Router(config)#interface GigabitEthernet0/0/1Router(config-if)#ip address 192.168.2.254 255.255.255.0Router(config-if)#no shutdown

查看路由表，C打头的是直连网络

验证连通性
从主机端使用ping命令来测试网络的连通性。
发现没有ping通。
这时我们给两台PC机加上网关
