Bias-Free Language
The documentation set for this product strives to use bias-free language. For the purposes of this documentation set, bias-free is defined as language that does not imply discrimination based on age, disability, gender, racial identity, ethnic identity, sexual orientation, socioeconomic status, and intersectionality. Exceptions may be present in the documentation due to language that is hardcoded in the user interfaces of the product software, language used based on RFP documentation, or language that is used by a referenced third-party product.

Chapter: Planning to Configure the GGSN
Planning to Configure the GGSN
This chapter describes information that you should know before configuring the GGSN.
This chapter includes the following sections:
•
Supported Standards, MIBs, and RFCs
Prerequisites
Planning Your Access Point Configuration
Before you begin to configure the GGSN on your router, you should know which networks your mobile users will be allowed to access using the GGSN. Once you identify the networks, you can plan the physical interfaces to configure on the router for those networks. Then you can plan the associated access points to those networks and configure them on the GGSN.
For example, you might want to provide user access to the World Wide Web through a PDN, plus access to two private corporate intranets. In this case, you need to set up three access points—one to enable user access to the PDN, and one for each private intranet.
Restrictions
The number of PDP contexts supported on the GGSN is dependent on the memory and router series in use, your GGSN configuration (whether a method of Point to Point Protocol [PPP] has been configured to forward packets beyond the terminal equipment and mobile termination), and the rate of PDP context creation to be supported.
The following list shows the maximum number of PDP contexts supported on the GGSN according to the memory and router series in use when a method of PPP has not been configured:
•Cisco 7206 VXR NPE-300 router with 256 Mb RAM—80,000 PDP contexts.
•Cisco 7206 VXR NPE-400 router with 512 Mb RAM—135,000 PDP contexts.
For information on the maximum number of PDP contexts supported on the GGSN when a method of PPP has been configured, see "Overview of PPP Support on the GGSN" section on page 7-1.
Supported Platforms
