- What is SD-WAN? say GOODBYE to MPLS, DMVPN, iWAN... w/ SDN, Cisco and Viptela
Software-Defined WAN (Wide Area Network). What is it? How is it different from DMVPN and iWAN and are we still using MPLS? SD-WAN is changing the game and it took me a bit to WRAP MY HEAD AROUND IT because it is STRANGE!!

Is it even worth it to begin on CCNA now? I keep seeing this SDN non-CLI stuff and the networking tech seems like its moving forward fast... its got me thinking the traditional CCNA skills are going to get pushed away? Idk Im sure Im overthinking this but it is a worry I have. Like would it be better to focus on security or something else?
I was just thinking the same thing. I just got my CCNA this past Friday, now i'm wondering if I just wasted my time.
I just did my network+ and havent even started on ccna yet
I'm a new CCNA but I'm sure we'll be alright. Not every company is going to be a large enterprise running the biggest baddest technology. Keep your head up and push forward.
The fundamentals still apply and the CCNA/NP/IE assist in providing this. Add in a programming language like Python (which is what I'm getting into).
You will still need to know how switching and routing works, which the CCNA covers. SDN isnt mainstream yet and knowing it now is still considered a bonus and not a necessity. But if want to be ahead of the rest, you can get into SDN.
I'm studying for my CCENT currently and really enjoyed this video, love how you break it down and the passion in your voice about this new technology. Some people will be boring in describing it then I lose interest. You channel is awesome bro, keep making great vids like this. I hope to be on your level soon starting with this damn CCENT. God Bless!
Another great video Chuck! I just love how you take a complex subject and make it interesting and easy to understand. Every time I watch one of your videos you always re-kindle my networking passion and push me to study harder!
I've always tried to understand the SD-WAN viptela Cisco solution. This video was very enlightening and extremely easy to understand. Great work NC!
Amazing watching this in December with no experience, the night before going for my interview at an ISP, then watching it again 7 months later as a Network Support Engineer. Thank you for sharing dude :)
I just implemented a large Viptella solution across 80 sites, I can assure you... You will be in the cmd line 90% of the time!
1000% correct.
@@NathanielScriven probably using that wrong! ^^
Please Google Bradford Technology much faster internet speeds and savings

The best video on TH-cam as of now to understand what exactly is SDWAN solution 👍
So I work for a IT company, but not in the engineering dept, so though Ive heard a few familiar terms/phrases, that whole world is foreign to me. Im 2 min in to this vid, and Im mad impressed with how you explain things and no lies, I learned a lot from this vid. great job bro
I love your videos and knowledge sharing to the community. Chuck, you're an awesome dude 🤘🏼
Chuck..I must say you are amazing at explaining things. Thanks for your giving back to the community
Very nice presentation! You have the gift of presenting difficult technologies in a simple way. Well done.
My company is deploying a lot of Veloclouds for our customers. I’m very interested in learning Cisco’s SD-WAN. Thanks for the video.
Make sure you talk to anybody that has experience of Viptella first.
Velocloud is phenomenal. Viptella not so much. When Cisco bought Meraki they were doing so bec it was IT made simple. With Viptella its the opposite. Ask anyone whos actually tried implementing it how easy it is to stand up and if it truly has all the spog features that are touted.
Hey, Chuck love your videos.
Need a video on your office setup it looks awesome.
huge thanks for these updates, Chuck Keith Sir! we really need bits of updates such as these from this side of the tech industry to keep us informed without having to go into the very details of them as we already have a heap of other things on our plate already. just enough to keep us updated. keep 'em coming Sir. thanks again!
Great videos Chuck ! you're making the networking fun and motivating us to learn new technologies, keep it up !!
Just got my CCNA, lovin it, so cool, Cisco all the way, been watching your vids, thanks for your help and support, need more coffee
I passed my CCENT Today Big thanks to you Chuck for the motivation!
Congrats. I take ccent it on the 27th.. I am so nervous and excited at the same time.
Gratz! I'm testing at the start of December...
@@larsonberggren8600 good luck i wish you the best

Great news! I just pass my icnd2 today too! Much harder...somewhat. good luck on ur journey!
I’m experienced with Cisco and security, but new to SDWAN. This was perfectly explained, engaging, and the examples were spot on. Thank you!
This was an amazing presentation! So much content in so less of time..still pretty clear
I only had a brief understanding of SDN, and hadn't heard of SD-WAN before. Great video explaining it and showing the main points. Thanks for sharing.
Man, we had velocloud come to our company for sdwan training and I can say I learned more from this video than the two days with velocloud. Great content.
Thank you!
Love your conent, Chuck. We are still in an over 6-month roll-out of SD-WAN, I work for a large multinational company with 10's of thousands of devices, we are still using some MPLS, but the SD-WAN is some cool stuff, I can already see a big difference.
Thank you very much great job introducing SD WAN technology now I need to learn it more.
this video just blow up my mind, I know how to work over cisco devices know about networking but this, this is another level thank you so much for share your knowladge.
Our organisation is testing our the SDWAN in a mini lab planning to do a full deployment. You have described our currenty network environment 100% from remote locations to office 365. Thanks for the video
thanks fo share Chuck, I took this video as my introduction to SD WAN, now I am very interesting so I will research myself how this technology works.
Wow, omg thats amazingly amazing!!!!!!
Loved your videos man, fan of your work.
Great explanations Chuck, its almost like you're a trainer or something.....hehe Thanks for the great content looking forward to future SD-WAN Videos on here or hopefully....someday.....my CBT Nuggets account.
Just saw you today at Cisco Live 2019 San Diego! Your beard did not disappoint. Keep it up my brotha!
Gosh I'm in love with your content delivery!!
Chuck your videos have helped me so much man, I literally love you and your content.
Awesome man! your explanation! when you show hardware with details!
Hey NetworkChuck Christmas is coming. You better start to prepare the 10 days of Christmas video series, we liked them a lot 😎🙏🏽

Yup
It was kinda hard for me at first to grasp the concept of SDWAN....but thanks to Cisco for providing a way to lab this thing....I now have SDWAN configured in my VMware environment and I can't get enough of SDWAN..🙂
Thank you. Sd wan is still new to me and this gave me some awesome insight!
This guy's voice is so soothing... Couple that with great content and you have a new sub!
Came for the beard, stayed for the delivery
Network chunk is awesome. Very Informative video presented with lot of coolness.
thanks Chuck, Great energy level and thanks for the short and concise video of SDWAN and to understand on high level.
Wow, that was great, thanks! So much change from the first time I built a shelf to hold up a WellFleet router. LOL!
I just discovered your channel. definitely solid material.
Good stuff networkchuck. Thank you for all your help :) hope to pass the CCNP soon
Wow - I haven’t been so captivated by discussions about networking. Gained a subscriber!
Thanks Chris! Welcome.
Awesome vid. Very informative.
awesome video. Answered so many questions I had. Thanks!
i bought boson because of you. im working on the ccent now, thanks for all your work bro!
I started working for a local Wireless ISP at the beginning of this year and we're starting to investigate SD-WAN solutions to implement into our network. Even for the small ISP network we've built, it's growing fast and we're trying to find ways to manage the transition as seamlessly as we can.
This was really good. I was looking for a good overview of SD WAN and NetworkChuck did a great job breaking this down and making it fun. Well done.
great review... thank you... 🙏🏽
Just found this channel. Excellent content my friend!
Thanks for this great video!
I oversee a 5000+ site MPLS network for a ISP/MSP. We started rolling out SD-WAN with Velocloud recently and my client is turning up four test locations soon. I've wanted to get my hands dirty with SD-WAN for a while so it's pretty exciting!
We've been moving a lot of sites to IPsec recently and some of the routing tables have become enormous. I can see how completely removing the control plane from the router will be an advantage here. Just bridging my modem at home and moving the routing duties alone to a separate router increases performance dramatically, so it makes even more sense in the Enterprise network.
I've heard of SD-WAN having issues contending with circuits taking packet loss. I wonder how the Cisco implemention handles this, especially when there is no latency.
I love the idea of load balancing at the application layer. LTE wreaks havoc on VoIP at random with jitter, latency, and dropped SIP MGMT frames, however it can have very good throughput. Another problem is many remote sites have a low bandwidth circuit that bottlenecks their other applications.
Having the ability to assign applications to the connection that suits them would solve both of these problems. We would no longer have to constantly explain that we can't control the cell reception in the building, or the congestion of the tower, or the inherent lower bandwidth of their other circuit. It would all just work, theoretically.
The Cisco implementation, as usual, seems quite advanced. I am curious to see how similar our implentation is.
I can't believe I heard someone from Cisco recommend against the CLI! 😱
Blasphemy!
Very interesting time for network technologies!
Chuck keep em coming my man!!!
Chuck, your enthusiasm is so inspiring.
I mastered Cisco IOS already years back , MPLS Dmvpn etc. that’s why I am doing Web And Mobile App programming
Very well explained, even with around 50 branches we are in a big mess considering routing and security!
Probably the best explanation of SDWAN I've seen anywhere...... Great Video
Thank you!
Chuck , you are the best .... I watch all your videos on CBT nuggets ... Keep going bro ....
Thanks Chuck, very informative SD-WAN explanation
This cracks me up. SD-WAN! SD-WAN!
We had almost all of this 15 years ago with Juniper NSM. We shipped the Juniper FW to the new remote store, plugged in the cable modem to the router, in thirty minutes, they could reach anything anywhere. Full mesh VPN with QOS and other goodies.
SD-WAN simply equals an orchestration and management platform for all of your edge devices.
If Cisco really wants to impress, I want to see a platform that auto-discovers assets, lets me draw lines between endpoints, add a few specifics, and then enables the comms I just drew. We should be long past the days of touching a switch/router unless it's broken.
Any half way decently trained tech should be able to fault find a network fault without going near a switch or router.
hi Mr.Chuck
i am very satisfate about your content , and i am pleased and thankfull for your vlogs. god bless you
I ended up here because the company I work for is migrating to this and I wanted to learn more. We have at least over 100 sites around the world and this is sounding really promising. Thanks!
Chuck! You're the man! Love every single video! Holiday give away coming soon? 🤔
Great info. We are preparing to deploy viptela's sd-wan solutions so I'm just getting familiar with it.
a part of me wanted you to start this video with : "HEY vSmart, Chuck here.. What is SD-WAN?"
my company has been rolling out a SDWAN solution (not cisco but a top competitor). It is pretty neat, and a lot of our "problem" locations have stopped complaining after making the switch. it sounds like all the sdwan providers hit the same features Chuck described like load balancing, fail over, ease of scaling etc.
One thing to note is this is still new, and no one has a perfect solution. There are bugs to be found. Sometimes stuff acts weird and i find myself wishing i was dealing with a plain old Cisco CLI & router. There's still a CLI running under the gui that can spit out wayyy more information. Think about it on windows.. you can go into the control panel (gui) and dig through settings for your ip address, or you and open cmd and type ipconfig.
I see a bunch of comments questioning cisco certs. The certs still teach you core fundamentals of networking, and protocols that are still very much in play with SDWAN.
SDWAN is not that new...other competitors have had it for awhile now...
shoe the maker Agreed bud.. our company is going with Verizon.. rollout in Feb can’t wait.. dynamic load balancing is what I’m looking forward to. For people out there looking to do Cisco certs , keep pursuing that cuz you still basic concepts to implement SD-WAN
Thanks for the Video and Illustration!
SO CLEAR! Thank you Sir!
AAR (Application Aware Routing) polices will steer the traffic. I suggest that you use something like a inline packet storm appliance to get the performance metrics for each application. The packet storm appliance will inject packet loss, latency and jitter over a given ckt. With the metric collected by the packet storm appliance you can tune your AAR policies. I hope this helped. Great video :-)
Hey Chuck, I just got done designing and implementing a cloud firewall solution in Microsoft Azure. I'm new to the cloud stuff but the last few weeks been reading and learning specifically on the solution that I put in. I guess my question is, as a senior network engineer, what's the best course of study to start getting up to speed on the SDN stuff. I've been working with this for about a month now and never associated it with SDN so now i'm starting to realize what all the upper level meetings are about the cloud designs they are thinking about. I only get bits and pieces of information but your video and some other reading I just did helped put some of that puzzle together for me. Better to wait on the new CCNP track in 2020 and go SDN or something I can do before that?
Edit: Not sure i'm asking this question correctly. Not sure if the two are related.
This is a great video! One of the only things that I found that actually gives a Sufficient explanation of what SD-WAN is without getting too dry with all the bolts underneath.
I have not used Cisco’s Viptela solution, however, I have a 40+ site deployment of SD-WAN using Talari Networks, and did PoC with SilverPeak & Meraki as well.
It’s unreal how much better SD-WAN is than traditional WAN connectivity! So much better that it Actually makes it difficult to sell engineers on it sometimes because it sounds too good to be true.
You do still face performance challenge is over the WAN with these types of solutions, but the approach to solving them is much simpler
I definitely encourage everyone to look at SD-WAN Solutions or any networked topology that spans multiple locations regardless of the quantity, as you can typically bring a FAR superior SLA to your organization/customers while simultaneously saving a significant amount of money. (Say what?!)
Chuck (or anyone for that matter), I am always delighted to have discussions surrounding these technologies. Feel free to reach out!
/Evan
most of time, the problem comes from remote side ISP connection.
Well now.. I recognize the fat guy in the green shirt ;)
Great video! It was nice speaking with you at the SDWAN booth!
Hi Chuck- nice review. Cisco is following Sophos RED (Remote Ethernet Device) example . This is the future - hands free no CLI site-to-site connectivity.
Execelent explanation! loved it!
Network Chuck You da man!! Question for you. Is there a video series on cbt nuggets about SD-WAN ? Thank you so much love your videos
Not the end of MPLS, SD-WAN will just add a management layer on top of it. As someone mentioned you can not rely on an internet based service if you need guarantees on availability, latency, jitter etc
EXACTLY Tim, SD WAN is just another financial mouth to feed and not really a justifiable ROI, not to mention more wiz bang widgets to fail that are not really any value add compared to a 'properly' designed and configured classic network
Agree; MPLS is still relevant, but SD-WAN certainly puts pressure on the incumbent providers. Still, if your locations support multiple providers (cable, fiber, cellular, satellite) it becomes much easier to justify saying “hasta la vista baby” to MPLS
Not necessarily. It depends on the implementation. QoS is not honored on a public Internet underlay, but with the right provider's solution, you can get an SLA with 99.999% or 100% availability when the design includes proper hardware redundancy and circuit diversity.
Most businesses will move towards whatever will save them money, regardless if MPLS is still better. With SD-WAN it can reduce a company's OPEX budget by 60+%
Agreed, MPLS has uses that will still be relevant. Like Traffic engineering
Thanks chuck! great material :D!
Great explanation! Probably the best out there. I was recently introduced to SDwan myself..
If I put my CIO risk management hat on and I'm sitting in front of a CFO who's asking hard questions; I'll choose MPLS for voice. Why? I like my time off.. I hate voice quality issues more than I love new tech. This is a risk management argument I'll bring to the table every time. You're basically outsourcing your routing. Same thing you're doing with MPLS but without the support horsepower of the ISP.. Whats your voice quality worth? Put a price on it.
I'm currently deploying a SDwan solution, from a startup vendor, for a large client. We're moving away from ISR's sharing BGP info with the MPLS provider and have ASA's with a fail over IPsec/GRE tunnels to the head ISR/ASA... It's breaking my heart.. It really is. Primarily because it works and we have 0 voice quality issues.
SDwan might be 'simple' but it's only as good as your plan to migrate and as good as the knowledge level of the folks deploying it. If they don't understand basic routing and networking; if they're not good listeners and their method of deployment is rigid; it's like talking tech with my greyhound. Actually, taking tech with my dogs is a LOT more enjoyable.
I fear this SDWAN stuff might be allowing some of us to forget how to be 'elastic' and confine us to the rules that these devices set, like 'inside the box' thinking.. Sure, SDwan is all these things sounds great in a sales meeting but my experience delivering this vendors SDwan solution has been pretty awful. I haven't even seen it work yet.. but if their deployment plan is any indication, it's going to be a total s%^ show once it goes live. I hear a lot of sales subterfuge AKA- double-talk.. AKA-- BULL-S^&*
So I'm not dogging SDwan, but I can't stress enough; SDwan doesn't change physics.. The basic rules of networking still apply. Planning still applies, maybe even more so.. Don't get caught up in all the hype.. You still need to be firmly rooted in network basics..
ya know its funny, we've had arguments about that with a hard headed CIOs and VPs before that would tear a strip off us when voice quality got the tinest bit of messed up. Now its move everything out, even Voice as a Service and now there is no conern for quality, like WTF?? MPLS is solid, it works. Now everyone is drinking from the same punch bowl and want to move services out of their datacenters, but in order in offer the same quality to these services, the network overhaul has to happen. I dunno, somewhere between TCO and ROI, not sure if this all add up yet.
I would rather sit inside the lav in an airplane on a 10 hour trip to somewhere really unpleasant, than do a SDwan deployment like the one I just did, again. Awful Experience..
We started to use SDWAN here from Citrix. I only can say that kind of tech is amazing. We have all of our branches running over SDWAN. It's like magic, man.
i like the content. keep it up!
Could you show the Service Level Agreement for the network connection when moving from 'MPLS' to 'home broadband' for your business?
from 99.9999 to 99.9
There isn't rely isn't SLA for cable networks. At least most of the time.
I work at a satellite branch for a Creative Arts college in Atlanta, Georgia that has 4 other satellite branch locations around the world. My Branch lost its Network Admin engineer last year around this time. My official title is Technology Specialist, I do some of everything at the college branch that work at. It's a little bit of Helpdesk, a little bit of Break / Fix, a little bit of remote tech, MDM solutions really everything under the sun. We just make sure that all the tech for the college works for the students and for our VP's. As I said before, we lost our Network Admin engineer last year around this time. At the time we thought that the college would find a replacement, but after a year of searching this Network Admin engineer position has gone unfilled. Most of the Network Admin engineer duties have been pushed onto me and the other Technology Specialist. Between the both of us we have been trying to keep our branch network up and running but over the course of the year our network has gone down 3 times. Each time the network has gone down, we have been lucky enough to get it back up and running. I've been watching your youtube channel for the past year to maybe glean some insight into the dark art of networking. I've been thinking about getting some sort of networking cert under my belt. What would you suggest I get, CompTIA Network +, CCNA, or CCNP?
Great video man! Keep it up!
SD-WAN and Viptela/Cisco really helped scale private cloud deployment. As the network evolves from connectivity to services to "federations" of ad hoc connections to share proprietary data between businesses this super, scalable, control plane capability becomes the key and "trust", authentication and peer to peer encryption (based on whatever criteria) becomes essential. Very nicely done.
I just came across your channel and it's exceptionally informative and very well done. However I do want to say that in your video your beard looks amazing! It's so shiny and healthy looking, would you mind sharing what products you use to care for your beard? 😃
Dope! Thanks Chuck!
Sounds like after I implement this I can just go ahead and fire myself?
hahaha
for sure :)
Yeah, maybe but first time there is a network problem your phone will be ringing for sure.
@@urbansubnet7753 As long as he's working for CISCO Tech Support! Haaa
basically that's the idea, freakin' Cisco!
Well done! This video is very helpful
Thank you!
Great vid, we use MPLS through around 100 sites and it is managed by the ISP however SD WAN might be the way to go for this!
Would I be able to use a current Cisco 4321 as I see that is a feasible router or would I need a whole separate router with the software on it to work?
I would look more into SD-WAN before making the jump if I were you.
thanks dude. Very informative.
i work in Cisco.. i can feel this drastic change.. i see your videos.. keeps me motivated..
Thanks for the comment Benson!
@@NetworkChuck thanks Chuck Kieth.. coffee is also my weakness hehehe
I'm studying for my ICND1, hoping it's still relevant after seeing this. My company is actually deploying the SDWAN solution across select clients now..
good video..velocloud...viptella..etc..etc..everything seems to be going to SDN including internal networking (think ACI)..not too keen on everything going the path of developers..i'm glad they still allow you to do CLI for troubleshooting which is what old school prefer to do..i'm wondering if they are going to add OMP to future coursework .. it would be cool to see what is under the hood with OMP if that is the major value add (on top of dmvpn automagically and vbonding with load balancing across asyncronous circuits)..good stuff though
I chose to get into networking 6 months ago and I'm taking my CCENT in one week, your videos terrify me that I may have made the wrong decision! I feel like the stuff I've been learning is ancient at this point.
Nate Bader take the exam. SDN will not supersede IP/MPLS within this decade. You still going to need the knowledge you will be gaining from the Cisco Routing and Switching Curriculum for you to be able to understand SDN. Im planning on taking the CCIE Routing and Switching within 2 years as it is still valuable in the market.
You are adorable Nate
The vSmart capabilities start to make those fail over circuits more cost effective since you can start offloading some traffic to them. This gives a lot more bang for the buck, especially as you scale to a larger number of sites in the network. This is an incredible change when presenting to executives and will fundamentally alter ROI Calculations for implementations of such technology in the Enterprise. This sort of technology could conceivably start producing an ROI within just a few months of implementation.
Explained it very well !!
Great video, very informative. You mentioned the new router reaches back to Cisco. Is this default behavior? Thanks
Awsome vid, thanks for sharing -- Chuck!
Thanks Luis!
In 2022, I still prefer the CLI for Cisco products. I was setting up a FirePower1120 series and VPN wouldn’t work until I went to CLI to run certain commands. Meraki works well as a GUI, but Cisco needs to step it up on GUI even if I personally prefer CLI. For Catalyst switches, I stay away from GUI. Hopefully they got it right on the SDWAN side, but reading the comment above seems like they have more work to do. Dell and Netgear M4300 have better GUI where you really don’t need to mess with the CLI.
Our requirement for low latency, jitter, etc. between offices disappeared. It was primarily for an old VOIP system. It HURT paying for MPLS for those sites until our contract was over. We just have basic IPSEC VPNs between locations now. There's a fiber line and a cable/FiOS/fixed wireless backup with failover. So much cheaper and we can change whatever we need whenever we need. I'm only dealing with 15 sites though, and our methods will only scale to a point. I also have to do cutover manually if a circuit isn't down completely. I wish I could get funding for something like this, but we're cheap.
Thanks for the break down Chuck. i subscribed to your channel :) Im not much for certs, but I like to understand the technology and read and watch a lot of material to try and keep current. Like you, have worked for a large organization(s) with multimple sites. I wasnt the prime networking guy, but liked to help implement the tech to better understand it and to keep my knowledge up. My opinion on SDWAN, I think it puts pressure on MPLS providers to offer better pricing and it seems to have started to happen already. I dunno, but I still think MPLS is a great solution and has always been pretty solid, and where you dont have MPLS, DMVPN is a great option to bring up a site. All vendors want to move to subscription models for gauranteed revenue: Cloud / IaaS / SasS all hoopla to keep the revenue flowing. What I find funny about this, is you have to overhaul your entire network and come up with a concept of SDWAN to make it useable, which from what you've described here seems to be easier to manage once you've converted...I do like that concept of it. On the other hand, one benefit of MPLS is typically you deal with one vendor/provider. When you go local internet at the site, you may have to deal with multiple providers, sign different contracts, have different SLAs, different support numbers to call to troubleshoot an issue at a particular branch. You might simplfy the "networky" portion with SDWAN, but you might complicate it down the line with what I mentioned above. As for those who contemplate the value of your CCNA, while I personally dont have one (meh maybe one day I'll get to it) you are still going to have local switches at your sites, and if you work for a larger org you will still probably have some sort of a datacenter footprint with a private cloud/virtualization setup. Ports still need to be configured, trunks need to be created, ether/port/VPC chanels to form, NAC to be implemented, ip helpers defined etc :). Definatley helpful for noobs that want to get into IT. Be thankful you werent around for token ring, thinnet, and nortel passport switching lol ;) (im showing my age and how long Ive been doing this stuff)
I came here for the network stuff. But i have to say, that pug is adorable. Those dogs are amazing.
