本文详细介绍Cisco路由器RT5和RT6的基础配置过程，包括主机名设置、密码配置等，并通过实例展示了如何实现PC与路由器间的Ping与Telnet操作，以及两台路由器间的互联调试。

一、 实验目标<?xml:namespace prefix = o ns = "urn:schemas-microsoft-com:office:office" />

（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

基本信息配置

Router>enable //进入特权模式

Router#configure terminal

Enter configuration commands, one per line. End with CNTL/Z.

Router(config)#hostname RT5 //配置主机名

RT5(config)#no ip domain-lookup //禁用域名查找

RT5(config)#enable password ip //配置特权密码为ip,密码后不能加空格，否则空格也作为密码。

RT5(config)#line console 0 //进入Console 口线路模式

RT5(config-line)#logging synchronous //信息显示自动换行

RT5(config-line)#password ip //

RT5(config-line)#login //配置登录线路密码认证

RT5(config-line)#exit

RT5(config)#line aux 0 //进入AUX口线路模式

RT5(config-line)#password bluefox

RT5(config-line)#logging synchronous

RT5(config-line)#password bluefox

RT5(config-line)#login

RT5(config-line)#exit

RT5(config)#line vty 0 4 //进入VTY线路模式

RT5(config-line)#password bluefox

RT5(config-line)#login

RT5(config-line)#^Z //ctrl-z退到特权模式

RT5#

RT5#show run //查看当前运行配置

(7) RT5的局域网接口调试

＝＝＝＝＝＝＝＝＝＝

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

PC1 网卡IP地址配置

在模拟PC上配置

IP192.168.10.10 24 192.168.10.1

PC1 与 RT5 的连通测试

<?xml:namespace prefix = v ns = "urn:schemas-microsoft-com:vml" />

RT5 Telnet密码测试

＝＝＝＝＝＝＝＝＝＝

T5#telnet 192.168.10.1 // PC1 Telnet RT RT5

User Access Verification //Telnet登陆认证提示

Password: //请输入VTY线路密码：bluefox

RT5>enable

Password: // 请输入enable特权密码：ip

RT5#

RT6的局域网接口调试

＝＝＝＝＝＝＝＝＝＝

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

Interface IP-Address OK? Method Status Protocol

Ethernet0/0 192.168.18.1 YES manual up up

＝＝＝＝＝＝＝＝＝＝

RT5--RT6互连链路调试

＝＝＝＝＝＝＝＝＝＝

RT5(config)#interface ethernet 0/1

RT5(config-if)#ip address 192.168.1.1 255.255.255.252

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

.!!!!

Success rate is 80 percent (4/5), round-trip min/avg/max = 32/52/68 ms

RT5#RT5#show run

RT6#ping 192.168.1.2

Sending 5, 100-byte ICMP Echos to 192.168.1.2, timeout is 2 seconds:

!!!!!

Success rate is 100 percent (5/5), round-trip min/avg/max = 1/1/1 ms

RT6#ping 192.168.1.1

Type escape sequence to abort.

Sending 5, 100-byte ICMP Echos to 192.168.1.1, timeout is 2 seconds:

!!!!!

Success rate is 100 percent (5/5), round-trip min/avg/max = 40/60/84 ms

(4)RT5 Telnet RT6测试
