路由器配置

教程

  1. 第一步：在路由器上配置路由器名和fastethernet0端口的IP地址
  2. Red-Giant>enable   ！进入特权模式
  3. Red-Giant # configure terminal   ！进入全局配置模式
  4. Red-Giant (config)# hostname RouterA   ！配置路由器名称为 “RouterA” 
  5. RouterA(config)# interface fastethernet 0   ！进入路由器接口配置模式
  6. RouterA(config-if)# ip address 192.168.0.138 255.255.255.0     ！配置路由器管理接口IP地址
  7. RouterA(config-if)# no shutdown     ！开启路由器fastethernet0接口

操作

路由器

第一步：在路由器上配置路由器名和fastethernet0端口的IP地址

  1. #configure terminal
  2. (config)#hostname ZWF_201921098102
  3. ZWF_201921098102(config)#interface fastethernet0/0
  4. ZWF_201921098102(config-if)#ip address 192.168.0.138 255.255.255.0
  5. ZWF_201921098102(config-if)#no shutdown
  6. ZWF_201921098102(config-if)#exit
  7. ZWF_201921098102(config)#exit
  8. ZWF_201921098102#
  9. 测试连接代码
  10. ZWF_201921098102#show ip interface fastethernet0/0

验证测试：验证路由器接口fastethernet0的IP地址已经配置和开启
RouterA#show ip interface fastethernet0 ！验证接口fastethernet0的IP地址已经配置和开启
或RouterA#show ip interface brief ！验证接口fastethernet0的IP地址已经配置和开启

第二步：配置路由器远程登录密码

  1. 第二步：配置路由器远程登录密码
  2. RouterA(config)# line vty 0 4    ！进入路由器线路配置模式
  3. RouterA(config-line)# login      ！配置远程登录
  4. RouterA(config-line)# password star    ！设置路由器远程登录密码为 “star”
  5. RouterA(config-line)#end
  1. ZWF_201921098102#configure terminal
  2. Enter configuration commands, one per line.  End with CNTL/Z.
  3. ZWF_201921098102(config)#line vty 0 4
  4. ZWF_201921098102(config-line)#login
  5. % Login disabled on line 66, until 'password' is set
  6. % Login disabled on line 67, until 'password' is set
  7. % Login disabled on line 68, until 'password' is set
  8. % Login disabled on line 69, until 'password' is set
  9. % Login disabled on line 70, until 'password' is set
  10. ZWF_201921098102(config-line)#password star
  11. ZWF_201921098102(config-line)#end
  12. ZWF_201921098102#
  13. %SYS-5-CONFIG_I: Configured from console by console
  15. ZWF_201921098102#

验证测试：验证从PC机可以通过网线远程登录到路由器上
C:>telnet 192.168.0.138 ！从PC机登录到路由器上

第三步：配置路由器特权模式密码

  1. RouterA(config)#enable password  star
  1. ZWF_201921098102>
  2. ZWF_201921098102>enable
  3. ZWF_201921098102#configure terminal
  4. Enter configuration commands, one per line.  End with CNTL/Z.
  5. ZWF_201921098102(config)#enable password star
  6. ZWF_201921098102(config)#

image.png
验证测试：验证从PC机通过网线远程登录到路由器上后可以进入特权模式
C:>telnet 192.168.0.138 ！从PC机登录到路由器上

第四步：保存在路由器上所做的配置

  2. RouterA# copy  running-config startup-config ! 保存路由器配置
  3. 或
  4. RouterA# write memory
  1. ZWF_201921098102(config)#exit
  2. ZWF_201921098102#
  3. %SYS-5-CONFIG_I: Configured from console by console
  5. ZWF_201921098102#write memory
  6. Building configuration...
  7. [OK]
  8. ZWF_201921098102#

验证
验证测试：验证路由器配置已保存
RouterA#show startup-config ! 验证路由器配置已保存
image.png

收尾：

RouterA#erase startup-config
RouterA#reload ！重启
提示是否保存配置选择“N”
重启后会出现这样的提示：Would you like to enter the initial configuration dialog? 【yes】:N

  1. ZWF_201921098102#erase startup-config
  2. Erasing the nvram filesystem will remove all configuration files! Continue? [confirm]
  3. [OK]
  4. Erase of nvram: complete
  5. %SYS-7-NV_BLOCK_INIT: Initialized the geometry of nvram
  6. ZWF_201921098102#reload
  7. Proceed with reload? [confirm]
  8. %SYS-5-RELOAD: Reload requested by console. Reload Reason: Reload Command.
