Overview of this book

Network Automation Cookbook is designed to help system administrators, network engineers, and infrastructure automation engineers to centrally manage switches, routers, and other devices in their organization's network. This book will help you gain hands-on experience in automating enterprise networks and take you through core network automation techniques using the latest version of Ansible and Python. With the help of practical recipes, you'll learn how to build a network infrastructure that can be easily managed and updated as it scales through a large number of devices. You'll also cover topics related to security automation and get to grips with essential techniques to maintain network robustness. As you make progress, the book will show you how to automate networks on public cloud providers such as AWS, Google Cloud Platform, and Azure. Finally, you will get up and running with Ansible 2.9 and discover troubleshooting techniques and network automation best practices. By the end of this book, you'll be able to use Ansible to automate modern network devices and integrate third-party tools such as NAPALM, NetBox, and Batfish easily to build robust network automation solutions.

Initializing the network snapshot with Ansible

In this recipe, we will outline how to open a session between Ansible and the Batfish server. In addition to this, we will look at how to initialize the network snapshot that we prepared in the previous step, as well as how to send it to the Batfish server.

Getting ready

As outlined in the previous recipe, the device configuration is generated, and the network snapshot is packaged at this point. Furthermore, IP reachability is now also provided between the Ansible controller and the Batfish server on TCP ports 9996 and 9997.
