ISIS I: Routing In Single Areas

This tutorial gives the reader an understanding of ISIS within the context of link state routing as a whole. The first of a two-part ISIS focus, this part provides an overview of the operational aspects of the protocol and the details related to its implementation in a single area, or flat topology. Throughout this document, comparison is made to the OSPF protocol, where appropriate, to draw out similarities or contrasts. Therefore, the reader would benefit from having a basic understanding of OSPF. Starting with some initial theory, this tutorial next takes a detailed look at implementation. Configuration specifics along with some troubleshooting tips round out the presentation.

This Study Guide is part of a two-part Study Guide Series addressing ISIS:
Part One - ISIS Routing In Single Areas
Part Two - ISIS Hierarchical Networks

Update: November 2002
The Part One and Part Two Tutorials have been revised and updated. They now include new sidebars, clarifications, and new material added by author Peter Van Oene.
