My name is J.D. Elliott.
I’m a network engineer.
This is a space to share what I’ve learned with you.
This is a comprehensive guide on deploying data center fabrics using the Nvidia Cumulus platform. Using Nvidia Air, we build each component of the fabric step-by-step, including basic system configurations, point-to-point links, BGP, MLAG, VXLAN, and EVPN. Additionally, we demonstrate how to install, configure, and use Ansible to manage NVUE configurations with ease and reliability.
In this lab, we build a sophisticated and flexible automation workflow for Arista EOS data center networks using Salt, Jenkins, and Github. We explain and demonstrate the entire build from the ground up, ensuring that network engineers who follow along will learn DevOps-like automation in one blog.
Subnetting is the first major hurdle which trips up many aspiring network professionals. There are plenty of guides on the internet for how to subnet, but these rarely explain the “why” of subnetting and often overcomplicate the method, which leaves students confused and frustrated.
This guide takes a different approach. We’ll explain everything end-to-end, including our tricks for fast and easy subnetting, practical examples of real-life subnetting scenarios, and routing concepts which are key to putting your new skills to use.
