一、 实验目标
（1）、熟悉Cisco设备基础信息及密码配置 。
（2）、实习那PCping通路由器局域网接口并且能telnet到路由器。
（3）、实现路由器之间互相ping通且能互相telnet。
二、 网络拓扑图
三、 实验步骤

1.
RT5的局域网接口配置
RT5(config)#interface ethernet 0/0 //进入接口模式
RT5(config-if)#ip address 192.168.10.1 255.255.255.0
RT5(config-if)#no shutdown //打开接口
RT5(config-if)#end
RT5#show ip interface brief
Interface IP-Address OK? Method Status Protocol
Ethernet0/0 192.168.10.1 YES manual up up
2.
PC1 网卡IP地址配置
在模拟PC上配置
IP192.168.10.10 24 192.168.10.1
3.
PC1 与 RT5 的连通测试
4.
RT5 Telnet密码测试

RT6(config)#interface ethernet 0/0
RT6(config-if)#ip address 192.168.18.1 255.255.255.0
RT6(config-if)#no shutdown
RT6(config-if)#end
RT6#show ip interface brief

RT5--RT6互连链路调试
＝＝＝＝＝＝＝＝＝＝
RT5(config)#interface ethernet 0/1

RT5(config-if)#no shutdown
RT5(config-if)#exit
RT5#show run
RT5#show ip interface brief
如果物理层administratively down ,是接口没有no shutdown
如果物理层up,数据链路层down,一般为物理链路故障，应检查物理链路是否连接好。
RT6(config)#interface ethernet 0/1
RT6(config-if)#ip address 192.168.1.2 255.255.255.252
RT6(config-if)#no shutdown
RT6(config-if)#exit
RT6#show run
RT6#show ip interface brief
