a. On R3, enable services with the global configuration command aaa new-model. Because you are
implementing local authentication, use local authentication as the first method, and no authentication as the secondary method. If you were using an authentication method with a remote server, such as TACACS+ or RADIUS, you would configure a secondary authentication method for fallback if the server is unreachable. Normally, the secondary method is the local database. In this case, if no usernames are configured in the local database, the router allows all users login access to the device. b. Enable AAA services. R3config aaa new-model Step 2: Implement AAA services for console access using the local database. a. Create the default login authentication list by issuing the aaa authentication login default method1[method2][method3] command with a method list using the local and none keywords. R3config aaa authentication login default local none Note: If you do not set up a default login authentication list, you could get locked out of the router and be forced to use the password recovery procedure for your specific router. b. Exit to the initial router screen that displays: R3 con0 is now available, Press RETURN to get started.c. Log in to the console as Admin01 with a password of Admin01pass. Remember that passwords are
case-sensitive. Were you able to log in? Why or why not? Yes. The router verified the account against the local database. Note: If your session with the console port of the router times out, you might have to log in using the default authentication list. d. Exit to the initial router screen that displays: R3 con0 is now available, Press RETURN to get started. e. Attempt to log in to the console as baduser with any password. Were you able to log in? Why or why not? Yes. If the username is not found in the local database the none option on the command aaa authentication login default local none requires no authentication. f. If no user accounts are configured in the local database, which users are permitted to access the device? Any users can access the device. It does not matter whether the username exists in the local database or if the password is correct. Step 3: Create a AAA authentication profile for Telnet using the local database. a. Create a unique authentication list for Telnet access to the router. This does not have the fallback of no authentication, so if there are no usernames in the local database, Telnet access is disabled. To create an authentication profile that is not the default, specify a list name of TELNET_LINES and apply it to the vty lines. R3config aaa authentication login TELNET_LINES local R3config line vty 0 4 R3config-line login authentication TELNET_LINES b. Verify that this authentication profile is used by opening a Telnet session from PC-C to R3. PC-C telnet 192.168.3.1 Trying 192.168.3.1 ...
