Introduction to Software-Defined WAN | SD-WAN

Everyone keeps telling you that you need to switch your traditional WAN over to SD-WAN, and you wonder WHY? 🤔

In this video, I cover EVERYTHING you need to know about SD-WAN (Software-Defined Wide Area Network) at a high-level. I ASSUME nothing. I walk you through the BASICS of SD-WAN, and HOW it operates under the HOOD. By the time you are done watching this video, you will be CONFIDENT in your ability to understand & articulate SD-WAN concepts 🤓

Having been a Network Engineer for over 18 years and an IT Instructor for over a decade, I take a lot of pride in SIMPLIFYING highly technical concepts because I strongly believe learning should be EASY and FUN 👊

Great content Naj! one question and probably a silly one, if VPLS is a layer two circuit then how does the ip addressing works over that network? is it encapsulated in some way? thanks

[lockch]

Do we need to change all existing hardware equipment in order to deploy SD WAN ? Any resources I can refer to about this ?
