Features Available From Previous PDSN Releases
The following features were introduced in previous PDSN software releases, and are still supported in
Release 2.0.
Integrated Foreign Agent (FA)
The FA is an essential component to mobility, because it allows a mobile station to remotely access
services provided by the station’s home network. The Cisco PDSN provides an integrated FA. The FA
communicates with any standard HA including the Cisco IOS-based HA.
AAA Support
The Cisco PDSN provides an authentication client that communicates with any standard AAA server,
including Cisco Access Registrar, to authenticate the mobile station. It uses the mobile stations’ name
(NAI) for authentication of the user with the local AAA server.
• The Cisco PDSN supports the following AAA services for Simple IP:
–
Password Authentication Protocol (PAP) and CHAP authentication.
–
Accounting information.
–
IP address allocation for the mobile user.
Note The Cisco PDSN supports the assignment of IP addresses and the mapping of MSID to NAI
for special configuration users. Typically, this includes MSID-based access users who skip
the authentication process during the PPP establishment, and who want just the Simple IP
routing service.
• The Cisco PDSN supports the following AAA services for VPDN:
–
PAP and CHAP authentication.
–
Accounting information.
• The Cisco PDSN supports the following AAA services for Proxy Mobile IP:
–
PAP and CHAP authentication.

Accounting information.

Assignment of IP address (as received from HA, in the Registration Reply message) during the
IPCP phase.

–
Optionally skip authentication during PPP upon receiving REJ from the mobile station.
