实验任务:
1.console线连接路由器
2.为路由器设置enable口令,并启用口令加密服务
3.更改路由器名字
4.配置vty访问权限
5.禁止路由器进行域名解析
6.设定路由器登录提示并保存配置文件
由于没有设备,实验采用的是小凡模拟器2.8中文版,采用windows下自带的超级终端连接路由器,小凡的配置就不述了
配置文件如下:
Router>ena
Router#conf t
Enter configuration commands, one per line. End with CNTL/Z.
Router(config)#enable password cisco
Router(config)#service password
Router(config)#service password-encryption
Router(config)#hostname R1
R1(config)#line vty 0 4
R1(config-line)#enable password ciscos
R1(config)#exit
R1#ip lo

R1#conf t
Enter configuration commands, one per line. End with CNTL/Z.
R1(config)#no ip domain-lookup
R1(config)#banner motd#This is my router,please enter your password.#
R1(config)#exit
R1#wi

以上注意一点,在配置enable密码和虚拟终端密码时,不能是一样的,否则会提示错误。这里的虚拟终端指的是telnet登录到远程路由器上需要的密码。
