IPLink Software Configuration Guide
10 • IP context overview
Introduction
This chapter outlines the IPLink software Internet protocol (IP) context and its related components. You will get
the fundamental understanding on how to set up your IPLink to make use of IP related services.
The following sections describe the configuration steps necessary to put together certain IP services and the ref-
erences to the related chapters that explain the issue in more details.
To understand the information given in the following chapters, carefully read to the end of the current chapter.
Before proceeding, make sure that you feel comfortable with the underlying IPLink software configuration con-
cept by reading chapter 2,
“Configuration concepts”
on page 29.
The IP context in IPLink software is a high level conceptual entity that is responsible for all IP-related proto-
cols and services for data and voice. The IP context performs much the same function as a standalone IP router,
and since every context is defined by a name, the IP context is named router by default. This IP context can
contain interface static routes, RIP parameters, NAPT, QoS and access control profiles.

on page 111, the IP context with all its related elements is contained within the grayed area.

The IP context undertakes the task of doing all IP-related transport of data and voice packets via the logical inter-
faces and available gateways. In addition, using profiles—which together with the IP context pinpoint how to
handle packets for specific services—enhances the possible field of application. Moreover, voice packets are
transported via a voice gateway to the CS context for further processing and forwarding to the PSTN.
IP context overview configuration task list
As previously described, this chapter outlines the IP context configuration. It does not give you all the details of
a configuration task, but refers you to the chapters in which you will find the full description.
