Simply awesome..i tried to understand basics of VXLAN 5-6 times through multiple documents but couldnt build up the concept. after watching this video, in 10 minutes i was able to write my own document on VXLAN. Great work David and you made this complex thing very easy.
Thank you very much ........... Such a complicated topic explained in such simple manner. I was really struggling with the concepts --- every link went very technical. This explains the concepts in a simple to understand manner, without going into the details ... Now, I can pursue the other links armed with this link. Thanks a lot. This made my job so much easier.
Thanks Neil. That was certainly my aim in this and other videos. I feel the same way about various topics where it's sometimes hard to find a intro to start with.
David, great presentation. It helped clear up some of my confusion in my efforts to understand VxLAN. The packet walkthrough and Wireshark capture were especially helpful.
Thank you, David for awesome explanation of VXLAN concepts. It cannot be any clearer :-) Yours is by far the best explanation I've seen. Much appreciated.
Great Job David! By far the this clearest and most complete day in the life of a packet for VXLAN. I needed just a few of the point but it was great to get the complete framing of the answer I was looking for complete with a drill down into the encapsulation of the pack with Wireshark showing the very same example complete with the VXLAN decoding. Awesome, really! Your model of how to demo network complexity of illustrate should be taken as a standard!
you are awesome sir.... very good explanation of overlay and underlay networks with vxlan tunnel encapsulation,,, I think your favourite colours are red and blue... since you have used for introduction of openstack neutron video.... keep going endless...
David thanks a ton for posting this.I need a quick clarification, without installing openvswitch-vtep.deb file i tried your topology and it works fine as i added flow entries manually as you show in the other demo. Then what is the purpose of openvswitch-vtep.deb file? I am also currently trying the same topology with ipsec_vxlan (with strogswan + ovs 2.4.0) but i am failing, so pls suggest if any
Phenomenal video - no other video or article explains things as well in layman terms. Maybe you could have a sidebar slide about the OSI layers, just so your viewers are completely informed.
Hello David Mahler. I think this is the best explaination regarding vxlan. I needed some help regarding vxlan tunneling. My scenario is that I have two seperate openstack clouds and I want to establish vxlan tunneling from an instance in one cloud to an nstance in another cloud. I have used microstack for cloud deployment. Can you recommend a video. thank you
Great explanation. In this example, the VNI was used to distinctly identify different customer routes at the VTEP end something like a VRF in PE MPLS. And it had no relevance in the underlay during its transit in the underlay. But, with in the VSWITCH, we are still limited by 4K vlans. Is that correct?
Thanks for your remarkable demonstration. I'm considering deploying the first OpenStack cloud in our company. A coleague from network team proposed that hardware VTEP on switches are more efficient for VTEP on open vswitches. Is it true? If so, how could hardware switch integrate with Neutron? Thanks.
I watched like 15 videos trying to understand this, and they all seemed over or under explained for my understanding. This one worked out perfectly.
That's awesome, thanks John!
Can't believe this was published 4 years back with so much detailed information for current industry adaption. Thanks David!!
Oh man, 4 years, me neither ha. You're welcome!
I know this video is getting old now but this really is the best explanation for this I have seen. Thank you for the effort
Thanks Brandon!!!!
I don't know why there would be 20 dislikes on that video. This is such fantastic content.
:shrug , thanks!
@@DavidMahler
Whenever it comes to clarify a conflict in understanding networking concepts. Mr. David Mahler is the man :) (bundle of thanks, once again)
Thanks again!
you have explained it beautifully ...nowhere in the internet it is explained as beautifully as you did..thank u so much
Thank you!
This is the real simple way of presentation where a person with Network knowledge can understand the concepts.. Thanks a lot Mr. David...
You're welcome!
Amazingly explained!! You're awesome!!!!
Thank you! 😃
Excellent.In a 15 minutes video, this could not be better.Would love to see more from you.
+Abinash Baruah Thanks, working on some OpenStack neutron ones when I can hopefully will get one of them out before the new year.
Simply awesome..i tried to understand basics of VXLAN 5-6 times through multiple documents but couldnt build up the concept. after watching this video, in 10 minutes i was able to write my own document on VXLAN.
Great work David and you made this complex thing very easy.
+sourabhjain18 That's awesome! I'm glad it helped you sort it out!
Very nice. After around 15 videos, this is the only video where I understood VXLAN concept. !!! Subscribed
Nice, thanks for commenting!
that wireshark part made everything crystal clear. god bless you
Great! Thanks for commenting!
Brilliant !! There cannot be a better video covering overlay networks covered in 15 mins , thank you David
Thanks so much Shiv.
Finally... I understand what it is. Beautifully explained. Thank you
Bhargava N.B You're welcome!
The most simple explaination for vxlan... Just awesome.. Great job David..
TY!
Although this video is old, I just started learning NSX and would like to say that I think this is the best explanation out.
Well done and Thankyou!
I should probably learn NSX too at some point ;-).
Thanks for the comment!
Simply excellent explanation. The wireshark demo was the highlight!
Awesome, I'll keep that in mind, thanks!
very detail and organized explanation.. thanks David!
You're welcome. Thanks for commenting!
Very good article David. Keep it up. Because of your article I had good insight into OVS and Overlay Networks. Thank you
Pradeep Varadarajulu Great! Thanks Pradeep.
Really clear to understand Overlay network. Good as usual.
Thank you sir!
You made it sound so simple. Thank you very much for the straightforward explanation of the complex topic.
You're welcome!

Thanks a lot David . The information is put in a nutshell and wireshark demo completes the understanding . Many many thanks !
Great, you're welcome Udaya!
After the 10-minute mark on this video I clicked the subscribe button. This content is awesome! Looking forward for more Cloud Networking courses.
Thanks for subscribing!
Probably the simplest explanation out, well done and thanks.

Sir you are simply awesome. U make complex concepts understand without any confusions. Thank you very much.
+Kiran Devraaj You're welcome! And thank you for the comment!
Complex topic explained in super simple way. I am fan of yours. Thanks for this video !!
Thank you!!!
very impresive ,I take as my network lecture presentation,thanks,David
Chillance Zen OK, glad it is of use for you.
David Mahler surprised that openvswitch does not implement multicast for vxlan ,will this feature be added in the future ?
Chillance Zen OVS with flow entries just does what a controller tells it to do with multicast....or by default in "normal" mode floods multicast.
David, saw it for the first time today, but its still in fashion :) Great job on breaking down Overlays. Thanks sir.
Ha, time goes so fast! You're very welcome!
David, great presentation. It helped clear up some of my confusion in my efforts to understand VxLAN. The packet walkthrough and Wireshark capture were especially helpful.

Thanks for commenting again Omer!
Superb explanation. Thank you.

Does this work the same way with TCP packets? The video shows UDP in the example and the wireshark captures.
Phenomenal video - no other video or article explains things as well in layman terms. Maybe you could have a sidebar slide about the OSI layers, just so your viewers are completely informed.
Thanks! Good idea, but with the encapsulation required it would be an OSI stack inside of an OSI stack, could be a little confusing perhaps?
Great content. Thanks David
You are so welcome!
Thank you so much! The fog is gone. Needed this clear foundation!
ringydingydo I'm glad it's lifted!
Thanks David!! Amazing content
Glad you liked it!
Nice explanation, Thank you for this video
Thanks for the comment!
Thank you for the clear explanation. Very good indeed !

Thank you and it was superb and clearly explained!
Thanks!
Can you also do one video on how VTEPS dynamically learn about the different mac address locations? I heard there is a BGP, MPLS and LISP options.
brilliant indepth explanation !!
+Clement Duval Thanks a ton!
Really like the openging, two castles and peagon messenger...
HAHA, thanks! I always wonder if this one was too cheesy.
I agree with other commenters succint and clear. I really liked the wireshark portion, icing on the cake. 10/10
jetmelt Thank you sir!
Well explained tutorials, thx for sharing Davd.
+Shri Sastha You're welcome!
Thanks for your remarkable demonstration.
I'm considering deploying the first OpenStack cloud in our company. A coleague from network team proposed that hardware VTEP on switches are more efficient for VTEP on open vswitches.
Is it true? If so, how could hardware switch integrate with Neutron?
Thanks.
Thanks! Great video, you explained the technology very well.
Thanks for the comment!
Thank you so much, easier to understand from your explanation
You're welcome! Thanks for the comment!
keep up the great job mate
Great job David!
TY!
Very good explanation.
Thanks!
