Cisco CCNP CCIE Enterprise ENCOR 350-401 - SD-Access

are you about to study for the Cisco encore exam and need a little primer on the subject of SD access well this videos for you hey what's going on YouTube Anthony Sequeira here and I am thrilled that you are joining me for this little introduction to the SD access feature don't make the mistake of fearing the unknown for many of you coming from a route switch and T shoot environment you may look at the blueprint for the Encore exam and go whoa all this SD stuff SD standing for Software Defined and as we're gonna see this just really isn't that bad what you need to know just from an SD access standpoint and let me explain to you where we're gonna deep dive Ronnie Wong and I an IT Pro TV have been really enjoying doing the deep dives into some of these specific technologies but it's important to understand what the SD access solution looks like from a bird's eye view let's take a look at the architecture right here you can see it starts with physical stuff that's right just because there's Software Defined Networking doesn't mean that you'll be out of a job they're still going to be physical equipment that you need to you know take care of even if you don't plan on getting into the high-end architectural you know Software Defined stuff but it's not that difficult so I encourage you to master at all anyways we've got our routers or switches our wireless equipment and then there's two hardware components granted the ice every time I've ever implemented it it was as a virtual machine but since the Cisco DNA Center and the identity service engine can be disseminated as physical appliances we've gotten there in the physical layer and those are two components that are going to make the SD access solution a reality now as we move up to the network layer notice we get into a concept that is common in Software Defined solutions and that is there is an underlay which is super fun to say under the underlay is where we are going to have our traditional routing mechanisms or layer 2 mechanisms if we're like rapid spanning tree protocol in a layer to environment the underlay is all of that stuff including the connections between the devices that we've set up and then the overlay at the network layer goes on top of that and makes all the software-defined magic happen so the overlay is going to consist of Lisp as the control protocol it's going to feature the X LAN as the data plane protocol and then it's going to feature Cisco's trust sack as what's called a policy plane of operation there at the network layer so that overlay is the magic that allows the SD access solution to be heavily automated and to be able to easily adapt as we are moving components from one place in the physical access layer it looks like just a physical access layer to them right as we're moving people in the access layer around and as devices are roaming and all that stuff is taking place it can just seamlessly adapt thanks to those overlay components so at the controller layer we've got our identity service engine this is going to be our triple-a entity this is going to be the device that's really making sure we can implement Cisco trucks trusts set for policy and then the Cisco DNA center notice one level up at the management layer we have the Cisco DNA Center GUI and this allows for automation it allows for design policy implementation provisioning and network assurance capabilities including machine learning analysis of your network so that this DNA Center controller can really take your devices through their entire life cycle it's not just about making sure the devices can you know react flexibly when you want to do different stuff so I thought I would wrap up this overview with a little fun exercise here let's take a look at a sample drag and drop like you might see in your exam environment I tried to compose this and we'll do so in future videos to be as absolutely difficult as possible right don't you love when practice questions are more difficult than the real thing you go into the real exam and you're like wow this is super simple thanks to those practice questions that I took so this dragon dropped probably a bit more difficult than you would actually see in the exam environment so we have these components on the left of the software-defined access solution and over on the right we have the little slots we got to drag them to what I would do if I were you from a strategy standpoint here is look for any obvious ones to you on the left or the right so for example the management layer as I'm looking I see well that could be the identity service engine or it could be the data center graphical user interface what's the best answer there I'm gonna go ahead with the DNA Center GUI at the management layer that's gonna take the identity service engine by the way and as I'm looking at what else there is over on the right that's going to take it and put it all the way down at that physical layer that's where it would go in this presentation and then as you're looking at these you see is is or as Bill Clinton once said it depends on what your definition of is is it was the worst Bill Clinton impression ever so is is is a routing protocol that is making a huge comeback I've had a blast teaching it in the end sled certification exam that's one of the electives that you could take in addition to encore it's the it's the 420 exam hey 420 yo man alright anyways so is is is actually the underlay technology here can you believe it so we slide intermediate system to intermediate system into our underlay as part of that technology and then this is where it gets super tricky we could identify lisp + VX LAN and cisco just sec as being our overlay technologies but what specific overlay technologies well you might remember from our discussion a moment ago we would put the cisco trust set at the policy layer there we would put the Lisp at the control layer and VX LAN at the data layer one of the reasons that VX land isn't the control plane intelligence there or better way to state it why Lisp isn't used as the data plane is that VX land can handle both layer 2 designs and layer 3 designs without an issue where lists would be limited more to the layer 3 type of encapsulation so this is a multiple drag-and-drop excuse me that is really quite typical for the dragon drops that you'll see in your on for exam only as I said this one might be a bit more difficult well let's click on the submit button and see how we did and sweet and I'll be back with more videos like this one on encore and many other subjects inside of the scope of Cisco's next level certifications thanks so much for watching and I'll see you here on youtube and at IT Pro TV you
