Using the System as Both a PDSN/FA and an HA
The system supports both Simple and Mobile IP. For Mobile IP applications, the system can be configured to perform
the function of a Packet Data Service Node/Foreign Agent (PDSN/FA) and/or a Home Agent (HA). This example
describes what is needed and how a single system simultaneously supports both of these functions.

describes what is needed and how a single system simultaneously supports both of these functions.
In order to support PDSN, FA, and HA functionality, the system must be configured with at least one source context and
at least two destination contexts as shown in the following figure.
at least two destination contexts as shown in the following figure.
The source context will facilitate the PDSN service(s), and the R-P interfaces. The AAA context will be configured to
provide foreign/home AAA functionality for subscriber sessions and facilitate the AAA interfaces.
