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.

Deploying nodes on BIG-IP devices

Using BIG-IP LTM to deploy an application requires load balancing of the application traffic across multiple servers. This requires us to define the servers/instances that are hosting the application. In BIG-IP, these instances are called nodes and they identify each server with a unique IP address. In this recipe, we are going to start deploying a new application (web server) on the BIG-IP device, and we will provision the nodes that are carrying this service using Ansible.

Getting ready

The basic setup for the BIG-IP should be already completed as per the previous recipes, and the correct VLANs to reach these nodes (physical servers) must be deployed.
