- www.bridgewhy.... is the name of our website where you can find all of our courses.
This video is the third video of SD-Access Series. It covers SD-Access data plane. It is recommended that you watch first two videos of this series which are "Introduction to Software Defined Access" and "Underlay and Overlay"before watching this video for better understanding.
We have compared how a packet moves in vxlan environment and compared it with normal switching.
All of our courses are available on bridgewhy.com
Below is the list for courses which we offer,
1. SD-WAN
2. SD-Access
3. Network Security
4. OSPF-BGP-MPLS from Scratch to Design
5. Routing Fundamentals
6. Network Interview Preparation Series.

What the hell dude , where were you all these years. Excellent explanation hats off to you . I wish I would have found this video sooner . Thank you very much and appreciate you work .
Thanks Srikanth !!!! I am glad that you liked my videos.
Excellent explanation!
After having part of live courses i.e Network Fundamental, OBM, Network Automation, now current ongoing course of Switching Fundamentals , and next Multicast, Vxlan i don't want to not miss anything from such Great trainer. Thank you very much sir for having with us for 20km of Smooth(strong) Tech Journey!!
Thank you so much Jeevan ji for your kind words !! It's my honour to discuss technology with you !!
Thanks for uploading this video, in conclusion, we have eliminated the painful STP issues with this overlay concept, marvelous!
I can bet, no one can describe as like you. Hats off to Bishnu.I want more content like bgp/ospf/multicast.....
Thanks !! I am in the process of creating more content. Stay tuned please !!!
Hi Pine Apple.. Please check my new video series. Here is the link of sample simple layer-2 packet walk..

Thank you for these great videos. They really simplify the concept. Please add control plane and VXLAN videos as well.
Sure Dude !!! Will add new videos soon.
I wud say one of the best video in youtube and one of the best trainer
I Think you should make ENCORE 350-401 series.
Hey.. Just released three more videos on SD-Access Control Plane.. Please have a look..
@@bridgewhy Thanks brother. Highly appreciated your efforts. You are the only one whos teaching fits directly into mind
@@SantoshSharma Thanks dude for such appreciation..
Because the port is blocked due to spanning-tree so ARP packet won't be forwarded over blocked link.
Correct !!!!
@@bridgewhy how do you know it is that link is blocked, not the interlink between the switch?
@@yanglijian Yes, correct, the blocked link could be the interlink between two switches.. the idea behind asking this question is that viewer is aware of Spanning Tree and it's consequences. And from your question, I am pretty sure that you have good understanding of STP.... Thanks..
Great step by step instruction!
Thanks Daniel!!
Simply Ammmazing!! Thank you very much!
Thanks Haider!!!
Very informative tutorial.
Thanks Jerry..
Thank you for these great videos
Glad you like them! Released few more on Control Plane.. Please have a look..
Superb video...good work
Thanks Dude!!
Thanks Vishnu for this good videos, very well planned and explained
Thanks Dinesh for the motivating comments !!!!
Amazing Video as usual
Thanks Samir..
Our teacher suggest to us this channel,and this is insane.
Where are you now sir ,make more videos like these
Thanks Ashok and I am glad that you liked these videos. Yup, will make more videos on new technology.. And yes, please say thanks to your teacher from my side to suggest my channel..
@@bridgewhy yes definitely
Aad I think they know u personally mr. @jitendra_jakhar
@@ashokguleriya4675 Indeed.. I know him personally and he was my teammate in Cisco.. Very nice and humble person and you are lucky that he is your teacher!! Keep learning!!!
If I'm not mistaken, the L2 ethernet frames ought to have dest MAC followed by src MAC - i.e. the ethernet frame with ARP request ought to be FF:FF:FF... | A:A:A... | ARP_REQUEST. From the drawing (NO VXLAN as well as VXLAN part) it seems that it is mentioned there in opposite order ( A:A:A..|FF:FF:FF..|ARP_REQ).. Hope I haven't missed anything.. Good explanation otherwise :)..
awesome videos great learning
Thank you 🤗
Welcome back
Thanks dude!!!
Thank you for your great explanation - short $ sweet 😂👍🥃
Thanks Dan Le!! Cheers!!!
Brother, your videos are great. I have watched most of these. Really I appreciate your effort. One doubt; In SD access, switch works for data plane only, but MAC Table is part of control plane. Then how switch can store CAM table?
Hi Tom.. Thanks for liking these videos. This is not the case.. there is a MAC table on switch.. Normal switching works as it is.. Just see the data plane videos again and you will get the logic..
@@bridgewhy thank you brother
May I know what is the encapsulation Method used here? Is it GNEVE ?
Hey... Encapsulation used here is VXLAN. We are using some of the unused bits in VXLAN header to propagate security tags. So VXLAN header is carrying information on both VNI as well as Securty tags..
@@bridgewhy Okay, Thank you :) I got it
Switch wont send arp request on the other link bcoz spanning tree will block that link, as two switches are trunked n not VPC’d together.
Yup !!! Yash, would you mind writing your question regarding ARP here? I am not able to see the full question..
The Bridge Hi Vishnu, thanks for ur response. My question was
1. In non vxlan scenario, source device knew Dest IP , Dest Mac, Source Mac but destination mac was missing, for which it does arp (broadcast to ff.ff...) but in vxlan scenario the actual source address and dest address are not even in the initial frame, but the loopbacks are present in d frame, in that case how does does control plane knows which destination sw loopback to provide address for,? Does CP node look at final dest mac address (broadcast mac ff.ff.ff) in its table and provides all dest sw’s loopbacks? Sorry for long writeup i am new to vxlan n know nothing on LISP yet. If answer is in LISP then i am happy to wait for your next video.
2. Recently from one of the cisco competitor vendor i heard them saying that vxlan was not designed with future enhancements (no TLVs) but in the initial videos you mentioned it has 2 bits of TLVs which it uses in SDaccess for tags (trustsec). So my qq was, are these TLV bits introduced recently and used just in sd access?
And are there more TLVs in vxlan encapsulation?
Thank you for your time and help with the great videos you are creating. Appreciate it! 😊
@@yashpancholi5765 Correct!! My next video will cover cover this.. mainly LISP will connect the missing dots..
@@yashpancholi5765 For your second question, I mentioned this in last video regarding what fields we are using in vxlan header to carry SGT's for micro segmentation.. And yes you heard it correctly that vxlan header was not designed for future enhancement and exactly this is why we are reusing the already coded field..
Because of spanning tree link will be blocked
Indeed.. You are correct!!!
