一、 實驗目標
（1）、熟悉Cisco設備基礎信息及密碼配置 。
（2）、實習那PCping通路由器局域網接口並且能telnet到路由器。
（3）、實現路由器之間互相ping通且能互相telnet。
二、 網絡拓撲圖
三、 實驗步驟

1.
RT5的局域網接口配置
RT5(config)#interface ethernet 0/0 //進入接口模式
RT5(config-if)#ip address 192.168.10.1 255.255.255.0
RT5(config-if)#no shutdown //打開接口
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 網卡IP地址配置

RT5(config-if)#exit
RT5#show run
RT5#show ip interface brief
如果物理層administratively down ,是接口沒有no shutdown
如果物理層up,數據鏈路層down,一般爲物理鏈路故障，應檢查物理鏈路是否連接好。
RT6(config)#interface ethernet 0/1
RT6(config-if)#ip address 192.168.1.2 255.255.255.252
RT6(config-if)#no shutdown
