Why you need to learn BGP EVPN Session 1 - Big Why behind EVPN

Want to learn EVPN, first lets understand why you should learn it
This is the first session in the series where we will understand why we need to learn EVPN. if you are some one working in Data Center, Enterprise or Service provider, EVPN is the way to go for control plane with robust evolving list of data planes like VXLAN, MPLS, SRv6. Lets find out more in our EVPN Basics to Advance series session 1.

Wow the way you unpacked this topic is amazing, you went back to give context on why these technologies were introduced and I want to believe that this is the best approach in explaining such a very hard and complicated topic within the network space right not. I have 20 years experience on enterprise and service provider networks. But this has been a very difficult topic to grasp for me, so thank u so much for the video.

[@emergingtechbytes]

@ngezas100 glad that you found this interesting. Thanks a lot for such a wonderful comment.

[@benhurkachhap1480]

Thanks a lot, Sunil, you amazingly put up the whole network transformation shift and helped me understand a lot of the new technologies why and when they were introduced, solving what problem, and in what sectors.

[@emergingtechbytes]

Thanks Benhur, glad to know that you found this useful.

[@ayushaudichya1]

Very well explained, Thank you 🙏

[@theonlyap78]

Thanks sunil. It was a good explanation regarding the evolution of evpn over other existing overlay/underlay protocols. Iam binge watching all your videos this week 😊.

[@emergingtechbytes]

Thanks a lot Arun, Glad to know that it was helpful

[@srinivasarao5467]

Wow, thank you Sunil, evaluation of networking explained simple way!!

[@emergingtechbytes]

Thanks for the comment Srinivasa..glad that you found this useful

[@benedictagyemang3862]

Very good videos, I like the design aspect of it. Thank you very much for sharing!

[@emergingtechbytes]

Thanks for the comment Ben, Glad that you liked the video.

[@user-xt6km1mb4u]

Finally found a video which explain the EVPN concept so well. Thanks a lot for taking time and covering EVPN. This was always hard for me to understand but you made it very easy for me. Kudos to the effort spent on this series.

[@emergingtechbytes]

Thanks for the comment. Glad that you found this useful

[@enriquegabriel7708]

The comparison between BGP and the Security Guy is one of the best examples I've ever seen in my life to illustrate how does BGP work in EVPN. Just amazing.

[@emergingtechbytes]

Thanks Enrique, glad that you liked the concept explanations..

[@harpreetsinghhoshiarpur4113]

This is a great presentation, thank you. Learned so much.

[@emergingtechbytes]

Thanks for your comment. Glad to know that you found the content useful.

[@MrManishgr8]

This is a good session on EVPN. Even though I am working on EVPN from a long time, I have learnt many new things in this session. Will wait for the next session. thanks for your efforts.🙏

[@emergingtechbytes]

Thanks Manish

[@nemo1697]

Thank you sir. I am learning for my JNCIP-DC and I can say I understood many concepts better. It's not easy to understand all things from books about EVPN - VXLAN and you explain it very well.

[@emergingtechbytes]

All the very best for your JNCIP DC exam. Glad that you are finding this useful

[@farhadctgbd]

Great Session sunil

[@emergingtechbytes]

Thanks, glad that you found this useful

[@Rohitvedi73]

Very good session, I switched from Data center to a big Enterprise company and actually we are deploying EVPN. Thank you sir for creating such a nice session on EVPN, planning to finish off whole series in this week.

[@emergingtechbytes]

Thanks, Glad that you are finding the series useful. All the very best for your EVPN deployment in Campus Network

[@kpraveenkumar2133]

We are using junos in our airports is the leaf spine arch

[@emergingtechbytes]

Thanks for the comments. Yes, even I have seen BGP EVPN getting deployed in airport campus networks, health care and other large enterprise segments.

[@user-pw9ex8pe1q]

This is indeed one of the complete and structured training on EVPN that I found freely available. All I can say is thanks a lot for taking time and making such a great series on EVPN, learned so much. Do you take any live classes Sunil, would definitely like to attend.

[@emergingtechbytes]

Thanks glad that you liked the series. Yes we do have some live classes as well. Please send an email to [e-mail] to register your interest.

[@voutlook]

Awesome outlook it will be nice to see it in Hinglish also sir

[@emergingtechbytes]

Thanks glad that you liked, you mean hindi??

[@voutlook]

Yes sir Hindi+english :)@@emergingtechbytes

[@mudassirazam5254]

what does transport label consist of ?

[@emergingtechbytes]

Hi, thanks for your query. Transport label is basically a MPLS label used for hop by hop switching in a MPLS network. Hope this helps and Happy Learning!!!

[@celine-um7ln]

Thanks for a great session. Can you please tell me what screen recorder software do you happen to use?

[@emergingtechbytes]

Glad that you found this useful, there are quite a few actually and I am yet to find a easier way to do this..one of them is MAC screen recorder.

[@celine-um7ln]

@@emergingtechbytes Thanks for the reply. Yeah the one you use seems very elegant. If you don't mind, can you paste the link to it so that I can explore it.

[@emergingtechbytes]

​@@celine-um7ln this one was screen recorder in MAC but i took help in editing as well as there was background noise

[@rabbizidniilma9633]

hi sir..what is the advantages of evpn sr over evpn mpls?

[@emergingtechbytes]

Thanks for your query. I am sorry but this is not the right question to ask. SR (Segment Routing) can work with two data plane options - MPLS (SR-MPLS) and IPv6 (SRv6). Segment routing is a control plane tech which offers you multiple data plane options as i said. Likewise, EVPN in the control plane can also run with MPLS in data plane or IP (VXLAN) in the data plane. EVPN in control plane with IPv6 in the data plane is coming as well. not sure if this clarify your doubt or not.

[@rabbizidniilma9633]

​@@emergingtechbytesu said in the talk that evpn vxlan,evpn mpls and evpn srv6..there i got confused...anyway with evpn mpls dataplane is mpls label..even with sr data plane should be mpls label...am i missing here something sir?

[@saifu62]

Right at 18:12 you said there were some issues in Vxlan flood and learn case that lend place to Evpn bgp as a solution .. can we talk what issues

[@emergingtechbytes]

Hello Saifu, Thanks for your query. initially Vxlan was implemented without any control plane protocol and relies on same flood and learn mechanism for layer 2. Host 1 and Host 2 being in the same subnet but connected to different switches over VXLan, when host 1 pings host 2, ingress vtep will flood this as host 2 MAC address is not known yet. so due to this flooding, that message will go to all the switches part of that VXLan segment. EVPN solve this by telling ingress switch that host 2 is being switch 2 so no flooding here. Hope this helps.

[@saifu62]

makes sense ! So just like Lisp in sd access the solution looks identical .. btw i have one more stupid query if may i

[@saifu62]

Are these vss and mc lag all these technology fading away?Sonce am starting my DC journey now .. am curious to know if that can be skipped

[@emergingtechbytes]

@@saifu62 yes you are right. EVPN is more of industry standard. Now even Cisco catalyst platfrom support EVPN.

[@emergingtechbytes]

@@saifu62 These are all vendor proprietary technologies.. to be honest there is not much to learn. I have explained in subsequent video about MC LAG where we are talking EVPN Multi-homing. All the very best for your DC journey, you will see vPC there which is another MC LAG type stuff only.
