​​Network automation begins with automating network reconnaissance. This is accomplished by gathering important information from network devices while building a library of dynamic on-demand utilities and generating living documentation. Starting small, the course exhibits the simplicity and elegance of network automation.

Next, you will learn how to automate larger changes that require a high number of repetitive steps. These changes will be executed serially in a specific orchestrated order, making them perfect for an automated solution. After gaining comfort with the new tools, you can fully transform network configuration management to an automated, intent-based, self-documenting system.

The final step is learning how to migrate to a continuous integration/continuous delivery (CI/CD) pipeline, thereby fully automating the network.

Automate Your Network

## Start gathering information
Gathering information about network devices and logical topology are the
next steps to network automation. The Ansible/Cisco `ios_facts` module is used to gather platform information, while the `ios_command` module is used to run commands and gather output. These are foundational
steps to build upon.

## Sample enterprise network topology 
The illustration below shows sample network topology typically used by enterprises:
