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?

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'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!

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've always tried to understand the SD-WAN viptela Cisco solution. This video was very enlightening and extremely easy to understand. Great work NC!

I love your videos and knowledge sharing to the community. Chuck, you're an awesome dude 🤘🏼

The best video on KZfaq as of now to understand what exactly is SDWAN solution 👍

Very nice presentation! You have the gift of presenting difficult technologies in a simple way. Well done.

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!

Great videos Chuck ! you're making the networking fun and motivating us to learn new technologies, keep it up !!

Chuck..I must say you are amazing at explaining things. Thanks for your giving back to the community

Wow, omg thats amazingly amazing!!!!!! Loved your videos man, fan of your work.

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.

This was an amazing presentation! So much content in so less of time..still pretty clear

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!

Just saw you today at Cisco Live 2019 San Diego! Your beard did not disappoint. Keep it up my brotha!

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’m experienced with Cisco and security, but new to SDWAN. This was perfectly explained, engaging, and the examples were spot on. Thank you!

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

Chuck your videos have helped me so much man, I literally love you and your content.

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.

I passed my CCENT Today Big thanks to you Chuck for the motivation!

This guy's voice is so soothing... Couple that with great content and you have a new sub!

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.

Wow - I haven’t been so captivated by discussions about networking. Gained a subscriber!

Gosh I'm in love with your content delivery!!

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.

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.

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.

Hey NetworkChuck Christmas is coming. You better start to prepare the 10 days of Christmas video series, we liked them a lot 😎🙏🏽

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.

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.

Hey, Chuck love your videos. Need a video on your office setup it looks awesome.

Good stuff networkchuck. Thank you for all your help :) hope to pass the CCNP soon

Thank you very much great job introducing SD WAN technology now I need to learn it more.

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

Thank you. Sd wan is still new to me and this gave me some awesome insight!

Chuck! You're the man! Love every single video! Holiday give away coming soon? 🤔

i bought boson because of you. im working on the ccent now, thanks for all your work bro!

Chuck keep em coming my man!!!

a part of me wanted you to start this video with : "HEY vSmart, Chuck here.. What is SD-WAN?"

thanks Chuck, Great energy level and thanks for the short and concise video of SDWAN and to understand on high level.

I just discovered your channel. definitely solid material.

Wow, that was great, thanks! So much change from the first time I built a shelf to hold up a WellFleet router. LOL!

Probably the best explanation of SDWAN I've seen anywhere...... Great Video

Chuck , you are the best .... I watch all your videos on CBT nuggets ... Keep going bro ....

Well now.. I recognize the fat guy in the green shirt ;) Great video! It was nice speaking with you at the SDWAN booth!

Just found this channel. Excellent content my friend!

awesome video. Answered so many questions I had. Thanks!

Network chunk is awesome. Very Informative video presented with lot of coolness.

Awesome vid. Very informative.

Awesome man! your explanation! when you show hardware with details!

Chuck, your enthusiasm is so inspiring.

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..🙂

Great video man! Keep it up!

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!

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!

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.

Thanks chuck! great material :D!

Very well explained, even with around 50 branches we are in a big mess considering routing and security!

Thanks for the Video and Illustration!

SO CLEAR! Thank you Sir!

great review... thank you... 🙏🏽

Video was intense. Good stuff!

hi Mr.Chuck i am very satisfate about your content , and i am pleased and thankfull for your vlogs. god bless you

Execelent explanation! loved it!

Thanks Chuck, very informative SD-WAN explanation

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 like the content. keep it up!

Dope! Thanks Chuck!

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

Great info. We are preparing to deploy viptela's sd-wan solutions so I'm just getting familiar with it.

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? 😃

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.

I came here for the network stuff. But i have to say, that pug is adorable. Those dogs are amazing.

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 :-)

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

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?

Explained it very well !!

I mastered Cisco IOS already years back , MPLS Dmvpn etc. that’s why I am doing Web And Mobile App programming

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.

Well done! This video is very helpful

I liked that you had Cisco Live as part of your video

thanks dude. Very informative.

Awsome vid, thanks for sharing -- Chuck!

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.

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!

I love that intro beat !

Sounds like after I implement this I can just go ahead and fire myself?

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)

impressive video. you just need a better mic to record on crouded places if I could leave a recomendation. it is the only point out of your quality video standard, that is pretty high. cograts for the summary, the best video I found on the topic so far.

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.

I think you should look into Fortinet and their products. I'm taking a cyber security education right now and it's mostly Fortinet, which has around 40+% of Sweden's market share of firewalls, while Cisco only has around 10%. Their products, especially their Security Fabric and their FortiGate (firewall) with a lot of management in a single-pane-of-glass etc. They are very underrated! Would love to see more videos about them :)

Thanks for the video, very good...

Nice vid bro! btw u have a cool black shirt! what brand u are using?

First rule of SDWAN club, don't tell what SDWAN is! 20 minutes to tell about ipsec with centralised route management

@5:15 i Don’t think Aaron liked that joke too much 😂 Great video though Chuck !

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.

hey I'm studying for my ICND 2 and this just made what I am studying obsolete, what the Heck Chuck. this was still good stuff to know and I'm just giving you a hard time so don't take it in the wrong way.....

Like the funny intro music & your dog
