Listening to this in the final few days before my DevNet exam really helps me grasp better of this whole concept. Thanks Hank and David!

This training video is the best explanation of the YANG NETCONF protocol model that I have seen. I too was confused about the container and leaf explanation until I watched this video. There are so many acronyms and it's hard to keep them all straight. Thank you!

I love the new angle Mr.Bombal, nice and crystal expertise :)

Incredible explanation, anyone looking to get their head around this has come to the right place. Channel is awesome, Thanks a lot guys

Excellent Mr Bombal. Thank you.

Hank Preston you are amazing. Really useful talk.

Great content, really helpful for my CCIE Data Center Written exam

This was the best content that I have seen or heard on KZfaq on this topic. Really phenomenal. Explained the topic in such an easy to digest and logical manner. Great great great job. I am subscribing this channel/speaker

Great video. Thanks David and Hank and greetings from Chile

Mr.David. Amazing!!!

Thank you both for great information.

Thank you very much! Very Informative and helpful for Final Graduation Exam !!

Cheers Hank & David

Thanks for this content David and a big up to Hank for taking time out to explain this stuff. I've been following Hanks tutorials videos and modules on Devnet since you introduced him on your channel and he really does explain things well. Anyone interested should really go have a look at Devnet it's great. Just need to complete my CCNP R and S and then going to try spend more time on this type of learning. Thanks once again without these videos I would still be pitch black with network programability now I'm just in the dark but see some light at the end of the tunnel. 🤓 PS any chance on some content regarding Cisco Cyber Ops at some point. If not I understand there is just so much content at the moment regarding Cisco and content sometimes it is hard to focus on specific things.

Thank you very much for the great lessons!

Really great explanation, thanks so much!!

thank you so much for yang/netcong serie it helped me a lot

Very informative! Thank you!

Good discussion, and well explained

thanks guys, it was very informative session

hey, very useful for the ccie rs written exam prep 👍

Sir you are great. .you are superhuman ...thanks

AT LAST this jigsaw comes together. Thanks, just excellent

This very nice video am watching it for the 3rd time , if you didn't not get it at first shoot it is ok read some documents and come back to watch then it will be more clear ...Thanks

Really good video! thank you

Hey guys great video. Always great listening to Hank. I was wondering what flavor if Linux is recommended to develop and play around in with respect to network automation. Thanks

If you want to get to the point where the topics are discussed go to 3:40

Excelent Video. I have an off-topic question. Does anybody knowns what is the screen font name used in the ssh text terminal??? It looks amazing to read!

Does data model mean syntax ( like the syntaxes for programming languages)?

passed ccie rs written. thanks 👍

Hello not sure if anyone will answer this old vid: but how can i extract the yang model from a particular device so i know how to address a particular part of the config? For example routing config? I'm struggling in building filters for netconf because i dont know the exact 'tree' to follow in order to get to a particular piece.

Awesome

Way to bridge the gap guys for us NetEng -> DevOps folks!

Hello David, Which book you can recommand me to read and understand Yang and Netconf pls. that is very interesting sir

👌😊

I never learned a thing about MIBS is my 6 years network journey. If YANG is like MIBS, where there is a too much of hype about YANG?

i see IOSv router has netconf. and does this router support netconf services same as csr1000v ?

Please add yang python examples David in your python courses, thanks

Does it also do "MATH" from the Yanggang....haha

I've got this error when try the command, anything I need to do first in order to run "pyang" command?? ---------------------------------------------------------------------------------------------------------------------------------- # ls -al total 84 drwxr-xr-x 2 root root 4096 Dec 13 15:20 . drwxr-xr-x 5 root root 4096 Dec 13 15:20 .. -rw-r--r-- 1 root root 70121 Dec 13 15:20 ietf-interfaces.yang # pyang -f tree ietf-interfaces.yang ietf-interfaces.yang:7: error: syntax error: illegal keyword: ----------------------------------------------------------------------------------------------------------------------------------

Hi Hank, just so you realize : Perhaps while you're designing a physical architecture ffor an infrastructure (setting up net hosts and routers), you do have a notion of a leave, . Even better, The "Spine" you're talking about, is the topological space in which the author you refer to, find "leaves". And there up ypour screen , you asked the executable "pyang", to display a dataset, structure as a tree. Hank, from the point of view of computer science academics, who think they do know about mathematics, they consider the tree you just displayed as a topological space. And guess, in that topological space, who happens to be a leave? Exacctly, the attirbutes. No leave is anything but an attribute. And look, No leave is anything else but an attribute. That's called a characterization. All in all, I really would give any engineer, to stay out of trying to explain abstrat concepts, without systematically finding concrete examples, or inferences. But that's just the mathematician mouth, who is doing something very mysreirous, with those SDN things... ;) Thank you anyway, as my previous lines show, I dived into the subject very quickly, though in an unexpected way.

Cisco... just stop... there is ansible / saltstack...
