## AI overview

This tutorial introduces an exercise in the IS-IS labs series that examines the data structures IS-IS creates to represent a network after configuring IS-IS routing for IPv4.

## Source excerpt

In the first exercise in the IS-IS labs series, you configured IS-IS routing for IPv4. Before moving on to more complex topics, let's explore the data structures IS-IS created to represent your network.
