配置路由器使用Cisco AutoSecure

配置路由器使用Cisco AutoSecure 实验过程：R1#auto secure --- AutoSecure Configuration ---*** AutoSecure configuration enhances the security ofthe router, but it will not make it absolutely resistantto all security attacks ***AutoSecure will modify the configuration of your device.All configuration changes will be shown. For a detailedexplanation of how the configuration changes enhance securityand any possible side effects, please refer to Cisco.com forAutosecure documentation.At any prompt you may enter '?' for help.Use ctrl-c to abort this session at any prompt.Gathering information about the router for AutoSecureIs this router connected to internet?
