实验一：路由器基本配置（1）--IP设置，用户名修改，远程登录。
工具：IOU一体化模拟器，secure CRT终端
一：IP设置
开启虚拟机-->打开IOU一体化模拟器-->输入用户名密码-->
之后步骤如下：

模拟器部分完成，接下来打开CRT终端
↓↓↓↓↓↓↓↓↓↓↓↓↓↓↓↓↓↓↓↓↓↓↓↓↓↓↓↓↓↓↓↓↓↓↓↓↓↓↓↓↓↓↓↓↓
连接主机192.168.1.114，快速连接2001、2002路由器。
如图，注意使用telnet协议，2001端口，主机名为192.168.1.114 2002路由器配置类似
注：本例中2001路由器hostname为Branch，2002路由器hostname为HQ
HQ>enable //进入特权模式
HQ#conf t //进入配置模式来操控网络
Enter configuration commands, one per line. End with CNTL/Z.
HQ(config)#in
HQ(config)#interface e0/1 //配置这个接口
HQ(config-if)#no shu
HQ(config-if)#no shutdown //开启这个接口
HQ(config-if)#ip address 192.168.1.2 255.255.255.0 //配置ip地址
HQ(config-if)#
*Sep 12 03:45:53.735: %SYS-5-CONFIG_I: Configured from console by console
HQ#ping 192.168.1.1 //ping 命令 测试与2001是否联通
Type escape sequence to abort.
Sending 5, 100-byte ICMP Echos to 192.168.1.1, timeout is 2 seconds:
!!!!! //！说明通了
Success rate is 100 percent (5/5), round-trip min/avg/max = 1/1/1 ms
HQ#
二：改名
HQ(config)#hostname ZH //HQ改名为ZH
三：远程管理
在2002路由进行如下配置：
HQ(config)#line ? //显示线路信息
<0-6> First Line number //6个接口
aux Auxiliary line //物理接口
console Primary terminal line //物理接口
vty Virtual terminal //虚拟接口
HQ(config)#line 0 4 //配置虚拟线路
HQ(config-line)#password qyt //设置密码
HQ(config-line)#transport input all //允许任何协议接入该设备
^
% Invalid input detected at ‘^‘ marker. //报错
HQ#show run | sec vty //查看正在运行的虚拟线路信息
line vty 0 2
password qyt
login
transport input none
line vty 3 4
login
transport input none //说明对线路密码的配置并没有保存
HQ(config)#line 0 ? //查看共几个线路
<1-6> Last Line number
<cr
HQ(config)#line 0
HQ(config-line)#password qyt
HQ(config-line)#transport input all
^
% Invalid input detected at ‘^‘ marker. //对线路0进行配置失败
HQ(config-line)#exi
HQ(config)#line 1
HQ(config-line)#pas
HQ(config-line)#password qyt
HQ(config-line)#tra in all //对线路1配置成功
HQ(config-line)#exi
HQ(config)#line 2
HQ(config-line)#password qyt
HQ(config-line)#tra in all
HQ(config-line)#exi
HQ(config)#line 3
HQ(config-line)#password qyt
HQ(config-line)#tra in all
HQ(config-line)#exi
HQ(config)#line 4
HQ(config-line)#password qyt
HQ(config-line)#tra in all
HQ(config-line)#exi
HQ(config)#line 5
HQ(config-line)#password qyt
HQ(config-line)#tra in all
HQ(config-line)#exi
HQ(config)#line 6
HQ(config-line)#password qyt
HQ(config-line)#tra in all //依次对线路进行单独配置，成功
注：正常情况下应该一次完成
HQ(config-line)#exi
HQ(config)#do show run | sec
HQ(config)#do show run | section vty
line vty 0 4
password qyt
login
transport input all //确认 成功
HQ(config)#enable password cisco //设置特权模式密码为cisco
在Branch路由远程登录HQ:
Branch>
Branch>enable
Password: //密码为CISCO
Branch#telnet 192.168.1.2 //telnet测试
Trying 192.168.1.2 ... Open //通
User Access Verification
Password: //输入线路接口密码：qyt
HQ>enable //成功进入HQ（2002）路由器，进入enable模式
Password: //输入enable密码：cisco
HQ#conf t //进入HQ的配置模式
Enter configuration commands, one per line. End with CNTL/Z.
HQ(config)#end //退出配置模式
注意：配置完成后 wr保存配置
