Example 2: Mobile IP Support Using the System as 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 GGSN/FA and/or a HA. This example describes what is needed for and how the system performs the
role of the HA. Example number 1 provides information on using the system to provide GGSN/FA functionality.
The system‟s HA configuration for Mobile IP applications requires that at least two contexts (one source and one
destination) be configured as shown in the following figure.
