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.

Building user-defined routes

In this recipe, we will outline how to control routing within a subnet using user-defined routers. This user-defined routes object can be associated with a specific subnet. We can define custom routes to adjust the forwarding behavior within a subnet in the Azure cloud.

Getting ready

The Ansible control machine must be connected to the internet, with reachability to the Azure public API endpoints. The Azure account should be configured as outlined in the previous recipes. The resource group, virtual networks, and subnets should also be provisioned as outlined in the previous recipes.
