Building a Network Automation Lab

Articles » Introduction

To complete the exercises included in the Building Network Automation Solutions online course (or to do your own exploration into the world of network automation) you’ll need a reliable lab environment. There are three major steps you have to complete to get there:

The rest of this document describes some of the potential approaches to building a network automation lab. Don’t limit yourself to what’s described here – go out and experiment.

Don’t Create a Science Project

Some networking engineers severely overestimate their skills in adjacent areas. Building a virtual lab for the first time with Vagrant and VirtualBox while fighting bugs in vendor Vagrant boxes can be a daunting task. If you’re new to Linux and virtual labs please try to keep things as simple as possible. Here are a few ideas (in increasing order of complexity):

  • Use my quick recipe to create your network automation environment and use physical network devices (if nothing else, configure your home router);
  • Install a workstation virtualization product (VirtualBox or VMware Fusion/Workstation) and create Linux VM and network devices from ISO images using GUI. You can still use my recipe and installation scripts to set up the network automation environment.
  • Instead of creating individual VMs for network devices, set up VIRL or GNS3 and enable outside access to network devices.
