4. The system then communicates with the foreign AAA server specified in the AAA context‘s AAA configuration
to authenticate the subscriber.
5. Upon successful authentication, the PDSN service determines the IP address of the subscriber‘s HA using either
an attribute returned in the Access Accept message, or the address specified by the mobile.
The PDSN service uses the Mobile IP FA context name to determine what destination context is facilitating the
FA service. In this example, it determines that it must use the MIP Destination context.
FA service. In this example, it determines that it must use the MIP Destination context.
6. The PDSN service passes the HA IP address to the FA service.
7. The FA service then establishes a connection to the specified HA over the Pi interface.
8. Accounting messages for the session are sent to the Foreign AAA server over the AAA interface.
9. If reverse tunneling is disabled, then subscriber data traffic would have been routed over the PDN interface
