Virtual Profiles
The next evolution of the dialer profile is the creation of a virtual profile. Virtual profile
information can be kept on an AAA server and associated with a user. The key elements to the
virtual profile are as follows:
·
The physical interface specification--This information is maintained on the router or
RAS device and is generic for any outbound connection.
·
The generic information about a connection that is stored in a template on the router
or access device
--This enables the physical interface to be divorced from the connection-
specific information.
·
The user-specific information that is stored on the AAA server--This information is
specific to the user and the connection and can be managed and maintained in a central
location, as shown in Figure 12-2

Virtual Profile Components
When a user has gained access to the RAS device and initiates an outbound connection, the
AAA server can provide detailed information on how to handle the user-specific connection.
The evolution is then complete. The router maintains the resource, and the AAA server provides
the information about the connection on a user-by-user basis. In this way, the router
administrator need only provide a resource and not the details regarding the use of it.
