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 Data Center Networks with Arista and Ansible

In this chapter, we will outline how to automate Arista switches in a typical data center environment in a leaf-spine architecture. We will explore how to interact with Arista devices using Ansible, and how to deploy virtual local area networks (VLANs) and virtual extensible LANs (VXLANs) in a Border Gateway Protocol/Ethernet virtual private network (BGP/EVPN) setup on the Arista switches using various Ansible modules. We will base our illustration on the following sample network diagram of a basic leaf-spine data center network (DCN):

The following table outlines the devices in our sample topology and their respective management internet protocols (IPs):
