Getting Started with SD-WAN | A Hands-On Overview

we're gonna uncover in a very quick overview what sd-wan is what the solutions are and how you can get started learning sd-wan the idea with software-defined stuff like software-defined wan or software-defined access or software-defined networking is that we can just define our intent for the entire business and let the software handle rolling it out for us and that's exactly what the idea with software defined when is when we have a business that has many different branches or organizations spread across a city or a state or a country or even the world we can allow software now to securely and automatically handle the configuration of our entire wan infrastructure now here's the thing software defined when is sometimes used as the actual name of a product cisco likes to brand their viptela solution as just cisco sd-wan but really sd-wan is a concept and many different vendors offer sd-wan solutions there is vmware dell emc's velo cloud solution there is hp's silver peak solution there is juniper's contrail and cloud orchestrated solution then there's cisco solutions and they have many different solutions for sd-wan such as meraki or the vitella sd-wan that i've just mentioned so what we're going to do is we're going to stick to a couple of the sd-wan solutions that i'm familiar with one of the easier ways that you can get started figuring out how sd-wan really works is with cisco meraki and guess what because of the devnet sandbox there's a way that you can get hands-on sd-wan experience right now let's check it out if you're actually logged in to cbt nuggets you can get exposed to sd-wan in a few different ways the actual sd-wan certification exam for cisco i can just search for it in the search bar e-n-s-d-w-i which is what we like to affectionately call the in sandwich exam i'll search for that here and we can see there is the sd-wan solutions certification prep right here on cbt nuggets what we actually do in that course is teach you how to deploy this right here on the screen each one of these blocks represents a unique site maybe around the world maybe this is something like a texas site and this is something like a california site and maybe this is something like nevada and you get the idea it goes on and on and on with sd-wan solutions you have one point of login one place that you log in to manage all of these sites around the world and beyond that with the correct sd-wan solutions you don't even have to configure these devices before you ship them to the site as long as they can plug in right here and get an internet connection they can be set to automatically communicate back to your one centralized controller and that way you just have to log into your controller and you can go about bringing all the configurations and security and design infrastructure all up to point this is called zero touch provisioning or ztp for short this is one of the biggest selling points about sd-wan solutions is that they are plug and play as long as you've bought it and attached it to your account this device will connect to the internet connect to your account and say hey i'm here i'm ready to be configured and you are off to the races it's a beautiful thing but then like i say you don't have to ssh into each one of these devices when it comes time to configure them you can simply log in to your front-end portal and start configuring your sd-wan solutions there now how can you get started getting hands-on with this again we've got the cbt nuggets content that will teach you how to do this but beyond that we can leverage a special tool one of my favorite tools and that's cisco's devnet sandbox if you go to devnetsandbox.cisco.com you can log in with a free account like your github account and then from there you can choose which sd-wan solution that you want to work with i'm going to choose meraki always on real quick so we get confronted with this large list of items to pick from i am going to choose the devnet sandbox and this is where we get logged in to our actual network where we can start looking at all of the different configurations that we can make with cisco meraki over here on the left hand side you may already be spying it there's security in sd-wan guess what that's because we can manipulate our entire sd-wan topology just like this topology here but within meraki firewalls and this is where i can start to specify some global parameters for all of my firewalls to implement if i have dual wan uplinks i can choose to throttle my dual lan uplinks i can choose to track my uplink statistics from a specific ip address beyond that i can choose my primary up link here or i can enable load balancing with just a checkbox think about that we can load balance out of our wan with just a checkbox all we have to do is just turn it on by clicking enabled and that's how easy it is it's fascinating but it gets so much more fascinating check this out if we jump down to traffic shaping rules what if i notice all of a sudden too many of my users are busy watching knox's youtube channel and i want to be like wait a minute you're using all of our bandwidth on youtube we need to slow that down i can create a new traffic rule real quick and i can set the definition to be something like under video and music then i can scroll down to youtube and now with youtube selected under rule number one i can say we're going to explicitly choose a bandwidth limit and we can throttle that sucker all the way down to 500 kilobits per second for a specific application look this is the fascinating thing about sd-wan is now instead of typing all of these commands on one firewall at a time or for a specific cider making all of this complex logic now these things are basically just drop downs or some fill in the blanks real quick or a check box and it deploys this robust configuration all for us we log to one portal to manage our entire solution and then with a few clicks we've deployed our intent to the entire business so sd-wan is an amazing technology and this has been introducing you to the meraki sd-wan solution what i can't stress enough is that when you get up into large enterprise businesses you may look into something like the viptela sd-wan solution where you start doing some crazy topology policies qos policies configuring hub and spoke or firewall insertion all of this awesome stuff that's what the viptela st wan solution brings to the table and again you can learn about either meraki or viptela sd-wan at cbt nuggets so that's been understanding why sd-wan is so awesome thanks for stopping by y'all i'll see you in the next one
