路由器的基本配置 实验目的： 熟悉路由器的基本操作λ 路由器的 3 种工作模式λ7 为路由器定义名称λ 为路由器添加特权密码λ 启用控制台密码λ 为 TELNET 访问启用密码λ5 不执行 DNS 解析λ 配置路由器，使得控制台端口不会中止你的连接λ 配置路由器，使得路由器发送的控制台屏幕的消息不会附加到命令 行中λ 配置路由器，使得当登陆控制台端口的时候显示一个标题。λ5 为路由器接口配置 IP 地址。λ 查看配置结果。λ 实验拓扑：

Router(config)#interface Router(config-if)# 为路由器定义名称
ethernet
router(config)#hostname xxx(xxx 为我们定义的名称) Router(config)#host fxh fxh(config)#定义路由器的名称为 FXH,那么对路由器定义名称,是为 了区别我们所操作所有设备的不同. 为路由器添加特权密码 router(config)#enable password sss（sss 为我们定义的明文密码） router(config)#enable secret cisco (cisco 为我们定义的密文密码) 启用控制台密码s router(config)#line console 0| router(config-line)#password xxx（xxx 为我们定义的通过 console 端 口进入路由器的密码） router(config-line)# login(启用密码) 为 telnet 访问启用密码 router(config)#line vty 0 4 router(config-line)#passowrd xxx（xxx 为我们定义的密码） router(config-line)#login 作用是为了登陆使用 *如果执行 telnet,必须设置 enable 密码和 telnet 密码才可以实现采用 telnet 登陆路由器。 不执行 DNS 解析
