David: I really enjoy your videos. They of necessity require in-depth discussion in order to understand the subject matter. The length is just right. Don't change a thing. Your collection of videos has a great span of complexity going from beginner through to expert level coverage. The key I find to your video's it that you provide enough detail for me (at least) to be able to duplicate your setup in GNS3 which then gives me a starting point from which I can continue to test and experiment. That in itself is a HUGE benefit. Keep it up!!! Many thanks.

Pls dont stop making these vids. I learn so much off your content. Your content is great. And yes, sometimes i have to watchbit a few times to grasp the concepts 💡. However, that is not boredom, its passion and wanting to add these skills to my bag and advance in i.t. rather than remain level. i like that the lessons are in 1 long video.

[linux_with_anakin]

Big fan of your content! Personally prefer the in depth stuff that you do like this video. I always find with programming and networking tutorials that the longer the better. A really in depth video that’s a hour or two long will teach so much more complex stuff than the surface level topics shorter videos cover. Thanks for everything you do!!

[jesusespinoza-online]

Hi @David Bombal!!! Thank you for all of your free content on Automation and Network Programability and for supporting the way to create the new Hybrid Networking Engineer!!! As you say... The next 10x Engineer!!! Best regards, and I hope to see you and meet you this year in Cisco Live Las Vegas!!!

[catharsis]

Everyone remembers what you said about time management & cutting out noise last year, and these videos are an additional help. The year to reach goals is this one, not next year. The longer videos the better!

[genc_emekli]

Your videos are all full of very useful content. I do not mind any length. Many thanks.

[malkta]

Yes please provide us more video about automation on Cisco and Python

[jesussaeta]

David absolutely I love your work, you have separated yourself from the rest. Thank you for helping me on my Cisco certification

[jonathanmblair]

Your video's on this series (past three and this one) are absolutely awesome. I was in a rut after passing my CCNA quickly (mind you with flying colors i.e. 900+ score due from your Udemy courses) but I failed my CCNP 300-101 test. I love Cisco, Networking, Python, Linux, etc but the fail threw me for a loop putting a huge doubt in my mind. I was studying feverishly to pass the 300-101 but always pushing the test off two days before it was due in PearsonVue as the fail was a blow. I watch your videos regularly but the past few with Linux totally rekindled my curiosity. They gave me that boost I needed. I found myself writing scripts and playing further discovering I knew a lot more then I thought I did. I didn't push my retake test off this week in PearsonVue for the 300-101 and I finally passed 850+. You do awesome stuff for the Cisco/Networking community and I thought you should know you pushed someone across the pond to do better. Thank you.

[yurisalarich]

Definitely one of my favorites videos from you David ! It really opens up a new World of possibilities

[tennysondesouza]

No matter it's 30-50 min video, Love to learn in dept from you Sir David, would like to see the post's

[kharos]

David I've been following you and networkchuck for a while and I've come to notice that you both give a lot in a different and unique way, I tend to be motivated by your videos and thrilled that I have a quality and in depth lessons waiting for me in your videos specially in yours, I wouldn't change a thing I would really like to help you deliver better content but I just don't know how to make it better so I can just say thank you for what you give already I like your videos but many times life catches up or I get distracted because I'm tired or something I've transitioned from a networking role to a developer role just by opening my mind listening to you guys even though my steps are slow I believe I've come a long way because hey I was just your classical Cisco fan boy, listening to you guys and dipping my toes on the deep pool that is IT as a whole I feel I've become a better professional for that I'll be forever grateful and I'll keep listening to both of you! Congratulations for making rich quality content keep it up!

[marvinreyes]

David... I just want to be just like you mate!

[jeffreyglennon]

Thanks again for another great video. When they are under 30 minutes I can watch during my lunch break!

[danielacosta]

Great vid, the 30 min vids are perfect, you are an amazing teacher. Thank you for all you do, we appreciate it.

[techymoh]

You always surprise us, learnt something new.
Not too long, and yes we would like those in-depth because they are well curated by you👌🏼
Also, I thank you very much for the ICND1 and 2 course with Wireshark Ethical.. Course, which actually gave away. I find them a lot useful. So thanks Mr. David♥️🔥

[ÐÞæ]

Thanks a lot David for this (certainly not too long video) and helpful insights. You explanation and examples are really helpful and understandable, even for me :-)

[panchaleon]

estoy aprendiendo python y desde hace tiempo que vengo estudiando redes cisco me enganchaste con eso subscrito y campanita saludos desde Vzla profe!

[Cleonexx]

David, this type of videos are just great! Please keep creating content like this!!!
