Really enjoyed this one! Greatly appreciate the insight.

Nice to see Petr Lapukhov again.

For the love of God, I can't understand a single word of Jeff T. 🙃

Much needed video podcast.

Both jeff’s respect ..I just respect/luv/adore U almost same as (Ken Thompson).Gr8 guys ignited countless minds and kept our stomachs fed/happy as well.

Great conversation!

Great episode as always!

In retrospect everyone can judge ❤

Great session. Full of knowledge and practical experience. Just one request, could you please add all the whitepapers/docs you bring up in the notes?

What a nice session! Thx. I am a big fan of this 2 nerd. Quick question on Free Valley routing. In case of IGP for underlay with no specific policy, the traffic via another Leaf to Exit point. It probably is useful there is NO traffic high-demanding. Could you give me another point of view for it?

Great talk. This has been one of my favorite shows you guys have hosted. Would love to see a future show on LISP with Dino and on BIER

Promo-SM

This echo a lot what i see in my organization. We try to push orchestration to different teams but they worry about supporting and not having the automation knowledge to maintain it.

Where can i get the slides presented here

Thanks for the great content! You both are Legends!

Very informative as always

Sorry to say that, but this session is very difficult to understand. The speaker is talking about details, options and differences between them without any introduction and visualization. Before he question what is a dragonfly topology was vaguely explained, about 15 minutes of discussion preceded it that was impossible to understand. It would be better to start from topologies that appeared around 30-35 minutes from the beginning.

Have you looked at vPC Fabric Peering functionality on NX-OS? It doesn't need peer-link and leverages EVPN fabric for that functionality of peer-link

There is an emerging nerd (Mel) ! Timely and relevant emerging technology ... time well spent. thank you all.

Looking forward to the continuation of this conversation! The intersection of ML and Networking is a fascinating topic.

Love that shirt JeffT …

why we need mac-only route-type 2 , if we already have all information in mac-ip route-type 2?

I would request to upload videos with better resolution than 720p. Specially the slides are very hard to read

JT seems to be a knowledgeable guy but his THICK ACCENT just kills it. It is so hard to understand coupled with his inability to show route type slides in bigger font just makes me extremely disappointed.

Such an amazing series, just found it and loved all the videos. Jeff Doyle has unique ablility to put things in simple words and give historical perspective wherever possible to clear things out. Jeff Tantsura clear and concise and to the point!!

This episode was the least informative of the series. Part 1 and 3 were pretty good in technical detail, not to mention the more structured format supported with slides. I do not doubt the guest's knowledge and expertise at all. I think he was either not able to articulate those well and/or too nervous about giving away any confidential information, which resulted in him providing almost no useful information at all. I understand the nature of proprietary information, but it should be possible to explain certain things without giving away actual implementation details. Nobody was asking for block diagrams for algorithms or code samples. As Jeff T mentioned in the beginning of Part 1, these interview series were inspired by the late discussions on the nanog mailing list and aimed to provide more insight, as well as shed some light on some of the items under question there. Those transactions were much more detailed and technical at a deeper level. You kept saying "we are all nerds here, please give us more details" and I barely saw that happening. I am sorry to say I learned almost nothing new from this and still have those questions unanswered. Anyhow, I appreciate all your time and effort to put this together, and always great to see you 0x2 Jeffs.

very nice

Clearly a real expert in the field, thanks for the very informative session.

proud of you as Junivator and X-Junivator. Thx a lot.

Thank you Sharada, Jeff & Jeff.

Great podcast, keep it up guy's 👍

Hi Jeff^2, Could you please create a session on the flooding list creation with the assistance of the dataplane ?

Thanks a lot Peter and Jeff for this great video. The concept of using BGP communities to prevent BGP path hunting is really interesting, but I am not 100% sure how this works. Let's say the FSW1 switch has 2 paths for an IP address behind the RSW1 - 1 primary (with the "rack_prefix" community) and 1 backup (with "completed_backup_path" community). How is the path hunting prevented if a prefix behind the RSW1 became unreachable? In my understanding, RSW1 would send BGP withdraw to FSW1 and FSW2. Both routers will start to converge, let's say FSW1 converges first, he can see the backup path via RSW2 and start to use this path and in the meantime it will send explicit withdraw to RSW2. RSW2 will now send the traffic via FSW2 (if FSW2 is not fully converged and didn't send withdraw to RSW2). Once all RSWx / FSWx are not fully converged, traffic is dropped. Probably I am missing something, could someone please explain? Thanks a lot !

Great talk, enjoyed listening to you guys!

Really a very good discussion. I wish if there will me more details on specific topics like MPLS implementations on scaling DC vs ECMP routing. What to expect in the near future? Are they any large DCs which currently in the path to embrace MPLS in DC?

Thank you very much. I really enjoyed this webinar, it opened my eyes beyond seeing the small picture of scaling DC in narrow environments and sees how big whales are trying to scale really giant DCs.

Without a doubt that was one of the greatest session ever!

Brilliant! So who is the exit point ? is it the responsibility of LEAF (Border Leaf like cisco) or TOF level ?

That was a great explanation thanks

I'm a late comer to the podcast, but I am enjoying these conversations so much. Thank you, gents.

Q

oh yes - the ugly stuff - allow own-as in 🤢

Yes - you can't know the whole system -> document as good as possible - which ususally mostly never happens

Has automation made human error more efficient - YES - breaking stuff with skill - YES - absoautomationlutely 🤣

have we done ... human factor ... I don't think so - at least from what I have experienced in the last 20 years

Hypothetical question around 13:14 into video - how about getting the ability to actually know everything in real-time about what is going on in the complex system? (well at least on a 1 second scale which is humanly possible)

Gosh I missed the show ! :(

Great Post many thanks for sharing.

Great interview! Thank you for sharing this enlightening session with us.

Excellent information. Thanks.
