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.

Deployment validation using Ansible

In this recipe, we will outline how to collect the operational state of the different networking components within AWS, such as VPCs and subnets, and how to check that our deployment is being implemented as per our design.

Getting ready

How to do it...

  1. Create a new pb_vpc_validate.yml playbook and populate it with the tasks to validate the VPC build:
$ cat pb_vpc_validate.yml...
