386 Chapter 12: Using AAA to Scale Access Control in an Expanding Network
Once the user has gained access to the remote access server by passing authentication, the user
then requests an interface to create a session. If the authorization is passed, the AAA server
provides the virtual template on behalf of the user, and the connection is established with the
user-specific connection information.
Virtual profiles provide the latest evolution for remote access. Throughout this book, the
connections made from an access server have gone from a unique phone number assigned to an
interface to a group of numbers associated with an interface with the dialer-map command to
dialer profiles. The last step, virtual profiles, completely disassociates the router from
maintaining the information about a remote connection.
For more information on virtual profiles, the Cisco Firewall and Securities class offers an in-
depth discussion of this topic. For independent study, you can turn to "Dial Solutions Command
Reference," for Cisco IOS Release 12.0, on the Cisco Documentation CD.
