ISIS 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.

Configuration specifics along with some troubleshooting tips round out the presentation.
