What is SD-WAN? say GOODBYE to MPLS, DMVPN, iWAN… w/ SDN, Cisco and Viptela

• 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?

• So single point of failure now? The controller goes down and the hardware goes actually dumb?

• you mean I learned ODR, RIP, IGRP, EIGRP, BGP andf such for nothing? Same crap with all the Novell Netware I learned in the 90s.

• Has much changed since this video? Is SD-WAN still the preferred network infrastructure for connecting data centers and managing the traffic? Do lots of cloud services still use MPLS?

• The background music is a mood 😊

• 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.

• Great video sir….❤❤

• But this feels more like this gives more control for major companies over the internet (or at least over the people running those WANs and connecting them together). So more censoring is going to happen in the near future

• Palo Alto Onprem Panorama SDWAN, what do you think?

• bro! how can I get tickets to these conferences like Cisco live?

• so we are turning routers into hubs?? or reverting/regressing these smart routers. Processors aren't that expensive. This sounds like Cisco was trying to reenergize their old switch managers. You still have to have someone trained and certified and now someone smart in SDN management. With proper vlans, qos and acl like what is already going SDN is extremely hard for a human to have the right skill sets to see problems that advisories will leverage – because they know making sure all SDN devices are setup properly by the admins is going to be harder as a whole.

• 8 yrs w SDWAN. Let me clarify. There are two types plus one. I will explain. 1 per packet. 2 per session if running voice or video. Per packet is preferred. The plus one can be either and offers things none other do.

• Please make a video about the SASE architecture. :)))

• That second phone behind you, the one on the right, looks like the same Cisco ones we have at work. The one above it looks like the ones we had before it. I'm not very knowledgeable of voip stuff (never had to manage it), also I love to hate on Cisco but the new ones are so much better, they sound a thousand times better than the old ones, especially on the speaker. The display is nice too, but I have some nitpicks with the interface. Sometimes I just sit there and listen to our phone bots talk and just appreciate how good it sounds.

• Sorry but Juniper is better ! <3

• Please do a video about SASE/SSE

• Cisco walking a fine line trying to push the SD crud on its loyal users. No one is using it. Takes the fun out of learning.

• speak english !

• I think we are confusing the different technologies here. SD-WAN is an overlay technology, whereas MPLS is the underlay technology. There's no such thing as SD-WAN will replace MPLS, they are completely different things and serve different purposes.

• too nerdy for me….

• Nice video, but I was missing some contxt – do you deploy SD-WAN as an overlay network on top of ISP-provided lease lines, custom WDM links, or how would you use that? SDN is fine and good, but if the traffic goes through ISP networks out of your control all the smartness of SD-WAN doesn't help you if the ISP throttles you or chooses suboptimal paths between sites.

• Too much Cisco; not enough SDWAN. I would have liked to have seen more examples from other vendors and comparisons or just keeping it generalized. Too much of this video felt like I was sitting through a demo for a sales call.

• No CLI? Enbelievable! I conf't believe it!

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

• data encapsulation on a crappy circuit is still … a crappy circuit….. no matter how many crappy circuits you can fail between

• Viptela & Meraki appear to be directly competing products doing much same thing. Where is Cisco going on this?

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

• I currently work for one of the biggest ISPs in my country (I have no proud being there because it's a big corporation who cares only in extracting the most amount from their customers delivering the least technology they can for huge profit margins but that's pure capitalism doing its thing, anyways… – oh… AS4230, for the record) and they are now deploying Velocloud and Citrix's solutions to the customers who have no self-love to the point they hire their services. It's 🤯 how this whole SD-WAN thing works and how easy it is to set-up and monitor everything – at least, from the perspective of the guy who is responsible to get in touch with the customer and setup everything from the "command center" side of things.

  Hard to believe there is such an amazing product from such a 💩 company.

• Just ordered three Meraki routers and learned that they're cloud configured. Is that SD-WAN with this management console too, or is Meraki it's own thing?

• Hi Chuck, great video content. Anyone out there with PaloAlto CloudGenix SDWAN and Prisma Access SASE solution experience? Seems to be a cool new competitor to Cisco. Especially the automated out of the box feature to connect SDWAN box to Cloud firewall (PrismaAccess/SASE/SIG [however u call it])…. Would be great if Chuck could explain and get PaloAlto as a sponsor of the video 🙄😊😃😀😉

• Chuck are there any labs available for SDWAN practice?

• Can you enable subtitle?

• What beard oil do you use?

• 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 🙂

• Ur video explaination suck , yaks not sure why I hate ur face.. instead of technical u focused more on dog your beard etc

• Hello, is there a way to find like a demo for the Vsmart console?

• so true. In service providers networks they will still running mpls because it´s benefits of label switching, free bgp core, path selection and so on. It's a very solid protocol that works very very well with any other L2 and L3 protocols, specially with IP. but in customers network they definitively will migrate to SD-WAN for it's lower costs and for the custom traffic control that it provides.

• +Plus

• You only talk and Talk and don't say anything!

• How do I get SD-WAN training online with hands on labs? I am Studying for my CCNP SDWAN certification. Thanks

• Hasn’t Juniper already done this like years ago?

• "thing like that", well – I use "things like that" 🙂

• Please do not mention o365 – I want to keep my dinner down.

• 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.

• Sir, I have purely work with traditional network equipment. I do need to be thorough in software defined networking as most of developed countries as moving towards SDNs. I'm planning to do DevNet exams. But, that's also not sufficient as I feel. Could you please tell me a way where I can get more hands on experience? I'm thinking of purchasing cisco devnet sandbox labs as well. Also I need to be a member in your group as well

• Thanks for this GREAT video content and explaining SD WAN, great work
  and keep posting your quality content
