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.

Configuring the underlay BGP on Arista devices

In this recipe, we will outline how to configure eBGP as the underlay routing protocol for our sample leaf/spine DC fabric. We are going to build the eBGP peering setup, using the P2P IP address between the leaf switches and spine switches. The BGP autonomous system number (ASN) assignment is as shown in the following table:

Node

BGP ASN

Spine01

65100

Spine02

65100

Leaf01

65001

Leaf02

65002

Leaf03

65003

Leaf04

65004

Getting ready

In this recipe, we are assuming that the interface and IP address information is already configured, as per the previous recipe.
