Hi i have a one small question, PE-PE MAC exchange happen in control plane but wat about PE-customer(hosts). Host will still send broadcast ARP to PE and PE will send to other PEs n then intended customer will reply? HOW PE --CE flood n learn is avoided in EVPN?

video is very informative get rid of background music to make it even better.

Hi, in Symmetric routing, in step 3 when traffic from VTEP1 to VTEP2, i believe the VNI must be L3VNI instead of L2VNI-20 right?

Thanks!

I think you should continue this tutorial. Better if you start with using Golang. Thanks

These are good videos thanks. Also can you please let know what are the reference documents used

really very good content being covered.

RT5 flew right above, a packet flow would have been really helpful.

Also you mistakenly told that the ESR will be shared and then a timer of 3 seconds will initiate, I believe you wanted to say that AD is shared and thus they discovered each other, post which the ESRs are shared and then the order list and then the DF selection takes place. Please correct me if I am wrong.

In case of VXLAN, when an NDF forwards the BUM traffic to the DF on the same ethernet segment, the DF should block it using the local bias (looking at the source tunnel ip), identifies the ESI, there is a mistake in reading. For MPLS, there is an ESI label which when the DF gets, it understands that this packet belongs to this ES, not sure what IMET label does here? Kindly clarify.

We talked about various features in this EVPN need for DCI, mostly what I could capture is again back to BGP control plane to prevent storm in the data plane, rest of the communities discussed along with IRB usage and how the multihoming scenario is used, kindly help us with labs taking the legacy DC vs EVPN DC.

Is this series over or are there more videos?

great video!

Did you do the video on how to implement VPWS by any chance? Great explanation!

excellent presentation. Thank you so much.

Amazing

Can we connect on LinkedIn?

Yes your content and animation is excellent but unable to listen properly due to background music

For all 3 different https application at receiver end will destination port remain same??

You dont need the music in the background. it is distracting

Thanks! I wrote my code and every tutorial shows to send payload as dict, I lost 4h looking for solution until I watched your video and changed payload dict to string as on your video. I was really close to madness, once again thanks.

Didn't understand this question: If mac addresses are learnt by a single LEAF/PE, how a remote leaf able to load balance towards multiple leafs? I believe we are talking about single active here right?? Can you clarify with the diagram example?

Annoying background music.

what's up with that annoying background music?

Great explanation!

Awesome explanation. Thanks!

nice video! thanks

Thank you for the clear and succinct explanation.

Excellent explanation, I am curious if I could achieve ECMP with different L3VPNs(VRF) taking different paths.

I don't drink beer😜. we are legends now 🥃

is it possible to dynamically include the link latency to the algo?

Came to learn evpn, left motivated to change the world

Better to include NOKIA cli as well Thanks

really good video, thank you

Ar 6:22, L1 sends flooding to L3 and L5. but how L1 know it has to send to L3 and L5, but not to L4 ? Is vxlan vni to vlan mapping is helping here ?

Can you drop the background music

Awsome Presentation. Here at 5:06, there is label 400. from where this label is captured ? I mean are we configuring this explicitly ?

keep going 💪

In a bgp routing scenario, let's say you have two ISPs with Router1 for ISP1 as primary link and Router2 for ISP2 as secondary or backup link. One day primary ISP had problems of several packet loss until after an hour it became unusable, so you need to divert the link/traffic and switch to the secondary link or ISP2. How are you going to configure this using bgp, what specific attribute do you put in this command or config?

Do you have the write up of whatever you are speaking, it is very well defined, and it would be good to keep that write up for future

But I can not see properly in mobile,can you make it simple background

please elaborate more on why we dont need GW for DCI?

👏🏼👏🏼👏🏼

Like the idea of addressing the facts in small chunks in a simplified manner. Kudos!!

One feedback, please remove this background noise, it is very much loud and very annoying. Either play it on very very low volume. Your voice is not clear at all

Great, Pls upload new Automation from scratch.

When CE send ARP packet where destination is all Fs then PE replicate that ARP message to flooding list (to other PEs with two label LDP + Service label received in IMET route). Question is: for this replication what will be protocol type. Tried capture in wireshark between PE to PE but not getting any packet matching with this information

Hello , thanks for this video please i have a question , Legacy PW to EVPN-VPWS Seamless Migration we have service Internet in Access-PE1( NCS 540 cisco )and also in Access-PE2 ( NCS540 -Cisco ) so we want enable EVPN-VPWS in both A-PE . so : we work in EVPN-VPWS single homed solution requires per EVI Ethernet Auto Discovery route so I have a problem for this command : p2p EVPN interface <type_number>.<vlan_id> neighbor evpn evi <evi_id > service <service_id>======> what is the method can allocate <evi_id > service <service_id> ?? i wait a reply from you .thanks

You seemed to have a good knowledge on this but, you are trying talk about it in a very poliched and bookish way, making it sometime difficult to understand the main content... My suggestion would be to just use the white board..Define the problem with the scenario and then say with type 4, we will will avoid this because it contains all these filelds and from there start expaling more about type 4 route...And if you still want to present all those bookish thhings please do it towards the end...
