Software on an external computer and use AAA to authenticate users with the RADIUS server. You will then use CLIĬommands to configure routers with basic local authentication by means of AAA. In this lab, you build a multi-router network and configure the routers and hosts. When a user attempts to log in, the router references the external server database to verify that the user is logging in with a valid username and password.

However, this approach is not very scalable because it must be configured on every router. For basic authentication, AAA can be configured to access the local database for use r logins, and fallback procedures can also be defined.

In addition to basic passwords, specific usernames or accounts with varying privilege levels can be defined in the local router database that can apply to the router as a whole. Configuring a privileged EXEC mode enable secret password further improves security, but still only a basic password is required for each mode of access. A user is prompted for only a password when accessing the router. The most basic form of router access security is to create passwords for the console, vty, and aux lines.
