The first access list allows telnet into the router. Your users will
telnet into router and authenticate with username foobar and password
"cisco"
The router will then immediately disconnect the telnet session. When
they successfully authenticate, an access list with their source IP will
be added to the dynamic list. Basically, if they authenticate correctly,
they can come in to the inside network. After 5 mins of inactivty the
entry will be deleted from the access list.
The vty 3 and 4 are using the rotary command so that you can telnet to
your router with the command: "telnet 1.1.1.1 3001" This takes you to
vty 3 (or 4). This way, you can telnet into the router and actually
manage it. A very subtle but VERY important point. If you forget this,
you’ll be making a trip to use the console port.
