一、实验目的
掌握路由器的基本配置命令
二、实验描述
主要实验内容如下：
1.配置路由器的名字
2.配置路由器的enable、secret、console、vty的密码
3.接口IP地址的配置及时钟
三、实验拓扑
四、实验设备
1.R2811 1台
2.PC 1台
五、实验步骤
第1步：配置主机名
Router>enable
Router#config terminal
Route(config)#hostname R1
第2步：配置路由器的密码
R1(config)#enable password jsj1
R1(config)#enalbe secret jsj2
R1(config)#line console 0
R1(config-line)#password jsj3
R1(config-line)#login
R1(config-line)#exit
R1(config)#line vty 0 4
R1(config-line)#password jsj4
R1(config-line)#login
R1(config-line)#exit
R1(config)#service password-encryption
第3步：配置banner信息
R1(config)#banner motd #
Enter TEXT message. End with the character '#'.
Welcome to jsj414 R1 -Authorized users only.#
验证配置：
Press RETURN to get started!

第4步：配置接口IP,接口描述及串口时钟
R1(config)#int s1/0
R1(config-if)#ip add 11.1.1.1 255.255.255.0
R1(config-if)#description s1/0 is DCE
R1(config-if)#clock rate 64000
R1(config-if)#no shutdown
验证配置：
R1#show interfaces serial 1/0
Serial1/0 is down, line protocol is down (disabled)
Hardware is HD64570
Description: s1/0 is DCE
Internet address is 11.1.1.1/24
MTU 1500 bytes, BW 128 Kbit, DLY 20000 usec, rely 255/255, load 1/255
Encapsulation HDLC, loopback not set, keepalive set (10 sec)
Last input never, output never, output hang never
Last clearing of "show interface" counters never
Input queue: 0/75/0 (size/max/drops); Total output drops: 0
Queueing strategy: weighted fair
Output queue: 0/1000/64/0 (size/max total/threshold/drops)
Conversations 0/0/256 (active/max active/max total)
Reserved Conversations 0/0 (allocated/max allocated)
5 minute input rate 0 bits/sec, 0 packets/sec
5 minute output rate 0 bits/sec, 0 packets/sec
0 packets input, 0 bytes, 0 no buffer
Received 0 broadcasts, 0 runts, 0 giants, 0 throttles
0 input errors, 0 CRC, 0 frame, 0 overrun, 0 ignored, 0 abort
0 packets output, 0 bytes, 0 underruns
0 output errors, 0 collisions, 2 interface resets
0 output buffer failures, 0 output buffers swapped out
0 carrier transitions
DCD=down DSR=down DTR=down RTS=down CTS=down
第5步:配置一个环回接口
R1(config)#int loopback 0
R1(config-if)#ip add 11.2.2.2 255.255.255.0
第6步：保存配置文件
R1#copy running-config startup-config （或R1#write memory）
Destination filename [startup-config]?
Building configuration...
[OK]
第7步：常用的show命令
R1#show ip interface brief
R1#show interfaces
R1#show running-config
R1#show startup-config
R1#show veision
