Unbelievable !! you are very talented , you have a great talent to simplify concepts and make them clear , this is the best VXLAN on UA-cam i'v ever seen , we need more and more data center videos from you my friend , please !
Wow, thanks! That makes my day! I found it really hard to find good information on this when I was learning it, so I created what I would have wanted to find 😀
i am working on a project that is implementing vxlan and your videos are my major support..........I understand there are lot many more related concepts which we cannot cover in short videos....though your videos are commendable and really helpful.
Thank you so much for the videos!!!! Very nicely presented and easy to understand. Can't describe how well you are explaining. You made a complicated topic look very simple. Hands down the best VXLAN learning videos. Keep up the good work!!
Concepts got cleared after watching this video. Too well explained in such a short video with appropiate and required information. Also the visual presentation helped to grasp the concept quickly. 👍
I've read so many blogs and books and not one of them explained these topics as well as you have. Really good work and pls keep posting new content. Hope you know you will help so many people.
Wow.. this is simply superb.. I don't think so anyone can explain the VXLAN concepts they way you explain... You made in simpler and easier to understand ..
Bravo - I have watched the first 4 videos on this subject and your explanation is quite easy to follow. Appreciate all the effort given to create these and looking forward to parts 5&6
I'm certainly late to the party here but I want to say that you have done a beautiful job of progressively gluing the subject together in a concise, modular format. I'm jumping into the fifth video thinking I may need to brush up on my BGP game before I continue 😆 this content is excellent!
Thanks for making VxLAN Concept so easy to understand. Salute to you for all the efforts in making these Videos and sharing them with all of us..Thanks again for the Kind deeds!
So I have seen all of your previous videos on the topic. As everyone states they are amazing. This one is as well but as we say around here, the stuff just got real! Much more complex and harder, at least for me, to keep up. Either way this is amazingly well put together and presented.
This is really the best and most insightful series I've found regarding this topic. Also, all of your videos have a very high quality and I appreciate your work!
I found that many articles on VxLAN jumped right in, without explaining the foundation concepts well. That is one of the things I’ve tried to do differently here. I’m really glad you like it
You are doing a grt work!! I am loving your content. I have one request. Please cover more topic like integration of BGP, ospf and other with configuration guides... Please post videos more frequently... all the best ... lots of love and respect from India...
Good question. VXLAN will use either flooding, or EVPN. Both are discussed in the next two videos, so I recommend starting there, and let me know if they don't answer your question
Glad you like it. I haven't planned anything on OTV yet, but it's becoming a popular request, so I might have to look into it soon. If you like DC technologies, have a look a my 'Six Nexus Tips' video. I'm sure you'll like it

Hi, I wonder how the VTEP can find the other VTEP to create tunnel in BGP EVPN. They send the discover information via BGP EVPN or which method? Can you help to explain? Thank you very much.
Good question. Yes, it's through BGP. Each switch has a VTEP, and each switch peers with each other switch. They all share NLRI (Network Layer Reachability Information), which includes VTEP info
Thanks. Very nice video. One question here.. can you explain how a newly added leaf is discovered in the topology and how the tunnel gets established between existing leafs and newly added leaf. If this is already explained in any video, please point me to that
Thank you for your great work! I got a question here, why HER needs BGP EVPN to send BUM traffic? It can be defined by user, for example 'vtep 1.1.1.1, 2.2.2.2'. It makes a group that receives BUM traffics. It does not have to use BGP EVPN only.
Hi and great video! I doubt if your statement is true about needing EVPN for VNI routing though. Its very vendor specific. Cisco built ASICs that now native support VXLAN routing and it was possible to "loop" your Arista on L3 ports to act as an external router on Broadcom chips.
I believe it was true at the time, but that may have changed. To my knowledge, even with Cisco's ASICs, you still need control plane learning to enable native routing. I'm not sure about other vendors though. I recommend having a look at this for the Cisco perspective: www.ciscolive.com/global/on-demand-library/?search=evpn&search.event=ciscoliveanz2018#/session/1507093641184001nGFE Thanks for bringing this up!
One of the best series on VxLAN and EVPN. If possible can you make a deep dive video and packet flow in IRB case? When and how L2 -vni and L3 vni are used? Thanks
Ok, so Data Plane learning doesn't have a gateway address, it is just like a layer 2 switch with hosts able to communicate with each other over that broadcast domain. Control Plane learning on the other hand, has the concept of anycast IP used as gw address, making the hosts connected to different vteps think they are all connected to the same layer 3 switch using same virtual gw address. Correct?
Very smartly you put all the pieces together and simplify very complex design, heads off man!! Can you tell me what is the limitation of HER over multicast, we have 20 racks so should we use HER or multicast?
Great Videos, Thank you very much. But I confused a little bit. As I understand Control Plane Learning can be two types: Multicast and Head-end replication and so Data Plane Learning can also be two types: Multicast and Head-End replication. Is it correct?
This was a very good explanation. But, you could have mentioned that the reason the anycast gateway is called an 'anycast' is because its configured on every VTEP's interface facing its respective access network. Also, that every VNI would have one such anycast gateway address. If that is the case, I am little confused how layer 2 VNI and layer 3 VNIs are different ...
Hi u r doing great I am also following ur website currently I am studying data center please upload more videos on data center we really need ur video because in data center there r no good video on UA-cam please make a DC playlist it would be a great help for students.
Network Direction u can cover any important topics related to DC which will be helpful to students for DC track certification (ccna ccnp ccie ) in future
6 years later and your video still helps alot
Unbelievable !! you are very talented , you have a great talent to simplify concepts and make them clear , this is the best VXLAN on UA-cam i'v ever seen , we need more and more data center videos from you my friend , please !
Thanks Mahmoud. I've got a few things in the works. Not DC specific at this time, but I think it will be useful all the same.
You are by far the best instructor to explain VxLAN and EVPN. I have watched several other videos and none of them explained as clearly as you have
Wow, thanks! That makes my day! I found it really hard to find good information on this when I was learning it, so I created what I would have wanted to find 😀
I have learned more in 10 minutes than 2h class training. Brilliant video. thx
Really really good to hear you say that!
Thanks!
Spent days searching for proper VxLAN material. Your video series is a Gem. Thank you for putting in so much efforts in simplifying this for us.
You're welcome! I found it was had to get this info, so I hope I've saved you some time
Nice, crisp and clean presentation. thank you
Thanks

Thanks very much, it's great to hear this
This is probably the best explanation of VXLAN I've ever seen - and builds on EVPN on top. Superb.
This is the best VxLAN explanation i've ever seen. Very simple and to the point.
Thanks Gnanadeep!

Simple and very well explained indeed. You´re here adding endless value towards where tecnology is heading. Thanks for sharing.
Thanks Cristian, I appreciate your support 😃
Excellent content. recommending this series to my staff. Great work.
Thanks!
Thanks for making VxLAN Concept so easy to understand. Salute to you for all the efforts in making these Videos and sharing them with all of us..Thanks again for the Kind deeds!
you're welcome!
Awesome video. this gave me a solid foundational understanding of BGP-EVPN. Simply stated and easy to consume. Excellent job.
Glad to help 👍
Your videos are the best videos I have ever seen. the best quality. the best animation. without nonsense talk
Thanks! That so good to hear.
I'm thinking of making CCNA videos sometime this year too
Super explanation man, please post more for data center
Thanks!
Nice video, very good pronunciation, understand you very well and English is my second language, no need for subtitle
That's some nice feedback, thank you
The best VXLAN video series EVER!!!!!!
Thank You!
Man... can't thank you enough for these videos. This has solidified my knowledge in VXLAN. Thank you!
You're very welcome!
It is excellent video. it cleared a lot of
confusion i had about data plane and control plane mac address learning.
Glad you liked it!
Such a great series, binge watching and learning more than I did reading a 400pg vendor book! Thanks!
Thank you, this is one of the best series I've ever seen on any networking topic. I have so much to learn.
Thank you, I appreciate that!
well done, great work. I will need to watch video 4 to make sure that I get the ideas clear
Thank you
Making notes for each and every word said...amazing explanation.
So I have seen all of your previous videos on the topic. As everyone states they are amazing. This one is as well but as we say around here, the stuff just got real! Much more complex and harder, at least for me, to keep up. Either way this is amazingly well put together and presented.
Thanks Mac,
I appreciate the vote of confidence 😎
It does get tricky, it’s definitely a complex topic. Stick with it, you’ll get there
To understand it better try to also see how EVPN works with MPLS. VXLAN is simply replacing MPLS in this case to suit the DC environment.
One of the best videos on vxlan
Thank you
Very good. I love the way the info is presented, so easy to understand!
God bless you my brother. You are saving lives.
i liked the video too but you need to calm down lol
PERFECT , NEVER SEEN ANYONE DESCRIBED VXLAN BETTER THAN IN THIS SERIES A+++
Thanks for the feedback, I appreciate it 😎
woah! explained so well. Thank you.
you're very welcome!
This is really the best and most insightful series I've found regarding this topic. Also, all of your videos have a very high quality and I appreciate your work!

Indeed. Love it
Great job on your explanations and graphics! Definitely the the best videos on this topic hands down.
It has ton of information. You explained perfectly and beautifully clarified all concept of this complex topic.. Just Awesome........ :)
Very well explained than most of the Videos. Able to understand easily.Good animation.Bing watching all the videos!!Thanks for Sharing.
Thank you very much!
Really appreciated. One of the best videos on vxlan out here.
Thanks Saikat!

Ocean of knowledge, things you explained I learned it. Thanks for making such content ful videos
Thanks man, Great video!
Thank you!
Beautifully explained !! Thank you
You are welcome! Glad you liked it!
Great Video, If multicast isn't applied, it will consider as Broadcast right? it is what I understand.
Good question. VXLAN will use either flooding, or EVPN. Both are discussed in the next two videos, so I recommend starting there, and let me know if they don't answer your question
Yes indeed !! thank you for putting all together ..
Fantastic video!! You're the best! Looking forward for more videos especially related to automation please! Cheers!
Glad you like it, thanks
Watched all of the videos up to here so far, extremely good and love the accent!
Not many people like the accent, so I appreciate this all the more!
Came across your series from a Reddit comment and I'm SO glad I did. Your videos are to the point and really break down the concepts well.
That's great to hear, thanks
Thanks for the simplifying the concept..I love your videos..
Please post videos for OTV and other DC technologies.
Glad you like it.
I haven't planned anything on OTV yet, but it's becoming a popular request, so I might have to look into it soon.
If you like DC technologies, have a look a my 'Six Nexus Tips' video. I'm sure you'll like it
@@NetworkDirection Please update..OTV or ACI video uploaded or not
@@summir7291 I don't have an OTV video. At this time, I have no plans to make one
@@NetworkDirection and what about Cisco ACI
@@summir7291 Sorry, no plans on ACI either
Great video, thanks so much! it is now 2021, what is now days the best way to handle both BUM and mac learning?
Really great videos. And the opening is a fine Arrested Development tribute. Congrats x2
The intro was definitely fun to make 😀

Good question. This is the beauty of the EVPN control plane (using BGP). Watch the next two videos, and (hopefully) it will make sense
The best VXLAN tutorial Thanks !! Great Job
Thanks Dror, that’s quite the compliment!
Good explanation. Good job.
Very well explained. Thank you !

Really good and very well explained.....Thanks a ton !!!
Excellet Videos' Thanks for making wonderful Videos
You're welcome, and thank you for the comment
Thanks for excellent explanation of VxLAN/EVPN concepts. It was very hard for me to decipher it by reading network vendor published information.
I also found the vendor information hard to follow. That's the whole reason I created these videos; So others could be saved the trouble!
nice & much informative for me as a beginner..
learning complex concept by simple method!!Awesom
Does the traffic hairpin because VXLAN uses split horizon?
Excellent, thanks a lot .
Glad it helped
One of the best series on VxLAN and EVPN. If possible can you make a deep dive video and packet flow in IRB case? When and how L2 -vni and L3 vni are used? Thanks
Part 6 covers some IRB. Have you had a look there?
It doesn't focus solely on IRB, so I'm not sure if it's deep enough for what you want
I have been missing something informational for a long time !!
Ok, so Data Plane learning doesn't have a gateway address, it is just like a layer 2 switch with hosts able to communicate with each other over that broadcast domain. Control Plane learning on the other hand, has the concept of anycast IP used as gw address, making the hosts connected to different vteps think they are all connected to the same layer 3 switch using same virtual gw address.

Very smartly you put all the pieces together and simplify very complex design, heads off man!! Can you tell me what is the limitation of HER over multicast, we have 20 racks so should we use HER or multicast?
If I can use vni to distinguish between customers, why do I need to use Rd and rt?
Very well explained....Also make video on VPLS and Openstack......
Thanks!
Great vxlan video!
Glad you like it!
Excellent works. Very clear and consistent
Great Videos, Thank you very much. But I confused a little bit. As I understand Control Plane Learning can be two types: Multicast and Head-end replication and so Data Plane Learning can also be two types: Multicast and Head-End replication. Is it correct?
Data plane learning uses flooding
It's absolutely great explained. Vxlan decapsulated.
Glad you think so! Thanks for watching!
Awesome video! I'm a Yank, but did get the BUM traffic comment...
