Configuring a Router
A router should be given a unique name as one of the first configuration tasks In order to accomplished this go to the global configuration mode with the following command:
Router(config)#hostname Tokyo Tokyo(config)#
Configuring router passwords
As a best practive restrict access to routers with a password. Passwords should always be configured for virtual terminal (vty) lines and the console line. Passwords are also used to control access to privileged EXEC mode so that only authorized users may make changes to the configuration file.
Console Password
Router(Config)# line console 0 Router(Config)# password cisco Router(Config)# login
Virtual Terminal Password
Router(Config)# line vty 0 4 (when configuring telenet sessions) Router(Config)# password cisco Router(Config)# login
Enable Password
Router(Config)# enable password SanFranciso Router(Config)# service password-encryption (to encrypt non encrypted passwords)
The enable password used to restrict access to the privileged EXEC mode IF the enable secret has not been set.
Sometimes it is undesirable for passwords to be shown in clear text in the output from the show running-config or show startup-config commands and a a best practice we should used the "service password-encryption" command
Password encryption
Router(Config)# enable secret <password> (encrypted password)
The enable secret commands is used to restrict access to the privileged EXEC mode The enable secret command should be used because the enable secret command is encrypted
