GGSN Configuration Example

This chapter provides information for configuring the system to function as a Gateway GPRS Support Node (GGSN) in
General Packet Radio Service (GPRS) or Universal Mobile Telecommunications System (UMTS) wireless data
networks.
Important:
context can be found in the Command Line Interface Overview chapter of the System Administration Guide and the
Command Line Interface Reference.
The most simple configuration that can be implemented on the system to support GGSN functionality requires that two
contexts (one source and one destination) be configured on the system as shown in the following figure.
The source context facilitates the following:
GGSN service(s) and Gn interface to the Service GPRS Support Node (SGSN)
GPRS Tunneling Protocol Prime (GTPP) configuration and Ga interface to the Charging Gateway Function
(CGF)
The destination context facilitates the following:
Access Point Name (APN) configuration
RADIUS authentication configuration and the interface to the authentication server
DHCP configuration and the interface to the DHCP server
IP address pools
Gi interface to the packet data network (PDN)
This configuration supports IP (transparent and non-transparent) and PPP PDP contexts as well as network requested
PDP contexts.
