I've been a networking professional since the 90's. I've NEVER seen anybody explain these topics in such a concise and clear manner. Thank you. Liked and subscribed.
Hi, Mr. Wallace, I give you this you have got a magic way to explain the routing protocol, that is just pure magic, I've never had so much fun listening to all these courses about routing protocol as I did with your lessons
He seems like someone who would be great to work with, knowledgeable and generous and friendly. Im a telco engineer for over 20yrs, worked on all layers 0-3 but the new software and cloud changes has got me having to seriously rethink the future landscape of networking. These videos offer an indepth summary, but each module you need to do a lot more to master it.
Thanks Kevin - I’m currently studying my CCNA 200-301 and this has to be the most informative and easy to follow dive into OSPF and has provided me with all the knowledge I need. Have set up GNS3 and replicated all your material to practice. Many thanks again for your time.
THIS IS AN ABSOLUTELY GEM OF A TRAINING ON OSPF. REALLY REALLY WELL DONE KEVIN. THE BRILLIANCY IS IN THE WAY YOU DELIVERED IT AND NOT THE AMOUNT OF THE INFORMATION YOU HAVE IN IT, BECAUSE I AM PRETTY SURE YOU KNOW MUCH MORE THAN THIS ABOUT OSPF.
What a fantastic video. I am practicing for my CCNA and have understood more than before about OSPF. Such a great, fun and easy to understand lesson. I will also watch all your other videos. Highly highly recommended. Thank you very much for sharing your knowledge.
Vert clear and informative! Thank you for your time and efforts in creating these videos, allowing people to learn for free. Please keep up the awesome work!
Thank you very much Kevin for your dedication and generosity, as always giving quality stuff for those of us who are looking forward to improve our domain in networking, I registered for the webcast but was unable to catch it live, becuase of work issues, but it's really nice to have the chance of watching it on youtube afterwards 🙏🏼😊
Kevin is so good at explaining and giving examples. Very clear and very informative video. I understand LSA types now, Thank you so much Kevin. You're the best
Super good coverage! Thank you for sharing your knowledge with us. The way you present things shows your passion and the joy of teaching! Keep up the great job!
Thank you very much for the video. I have already seen a few videos on the subject, but none of them have covered OSPF in such depth and accuracy. English is not my first language and with some dialects I have a lot of trouble following the videos. But your videos are so easy to understand and the content is explained so clearly that I just had to buy the ENCOR course from you on Udemy. You are a great asset to the networking community. Please keep up the good work! Greetings from Germany!
Thanks a lot for this amazing explanation. The notes I took helped me a lot, especially the one related to the network command because it was confusing me. Not only with ospf but eigrp also.
Thank you so much for explaining info that I found quite hard in such a simple and entertaining way. I am just starting my path into Network Security, and these videos are so much help :)
Really helpful videos sir, these really helps to get concepts clear, i mean your way of teaching is awesome, very nice and informative videos, if you can make some advance Deep dive on BGP and IS-IS that would be great too. Thank you again sir!!!
Hi sir amazing stuff and no doubt its tons of years experience you put in to explain, extraordinary, like default routes why don't we simply say default route rather than LSAs, R1-R2-R3 if R1 is connected to EIGRP, R3 is connected to rip etc so why don't we simply point it as a default route running ospf, or it will still fill up the routing tables on both sides i. E R1 and R3? Thanks
Thanks for this excellent video! It looks like it might have cut off early at the end. Are there also links for the demo and configuration pdf's and files like there are for your other videos?
Thank you so much for your videos. Very informative and interesting. I couldn't ask for a better teacher. One question, though: It seems you didn't enter the address-family command when configuring OSPFv3 on R1. Is this not necessary? Everything seemed to be working anyway, even though you applied the command for both ipv4 and ipv6 on R2 and R3. Or perhaps I missed something you said about it?
Error at 1:27:21. Init State is reached when a hello packet is recieved but that hello packet did not contain the router ID of the router of the recieving interface.
Hello i love what you do, i've looked your videos when I was preparing my exams (school, not certification) and i'm looking them again now that I have a contest in my country. It is a big help, It would be interesting to do one Deep Dive of BGP (eBGP and iBGP) but I understand it takes a while to prepare everything to do one episode of Deep Dive. Really Thank you for everything ^^
Hi Kevin,big fan right here! Didnt really understood if filter-list or distribution-list are kinda the same..I mean..can i use one instead of other and evrything will be ok?Thanks!
Question re:Stubby area/NSSA etc..around (58:00), Area0 will never be NSSA, Stubby area, or totally NSSA? I wonder if R3 gets connected to RIP first, Area 0 can be Stubby area? And then when R1 gets connected to EIGRP, Area 0 can become NSSA, totally NSSA etc.? Thank you for your great videos! I am almost understanding really well as I watched your Deep Dive series over and over again!
Area 0 as the backbone area, can never be STUB in any flavour. As mentioned in the video a Stub area is also consider an Edge, and Area 0 or the backbone, should always be a connecting point between adjacent areas. Hope that helps.
Hi Kevin.... As usual a great video from you. It would be great if you can make a similar video for BGP.... "DEEP DIVE BGP" as well..... thanks for the knowledge you share.
I love your content sir!! but i always had one question in my mind, why area 0 is only called as backbone area , why not area 1 or any? and whats the main role of backbone area? Thanks !!
What an interesting remark at 1:33:20 when you discussed about filtering between the Database and the RIB. If you have something as small as the example with 3 devices no problem. but that approach does not scale. For instance, if you have R5 connected to R1, then you need to make sure that the same policy apply in R1, will be the same in R5, if it is NOT, then R5 will receive the same LSDB thinking that R1 is possible exit point towards network that you don't install in R1's RIB, causing black hole of traffic. You may be lucky enough to have a default route to redirect such traffic, but that can also cause sub-optimal routing which is undesirable. I understand the reason for the example, but you should make a NOTE: don't do this in production environment or you can kill the network :P Other than that, great video, liked and subscribed... Next to consume BGP Deep Dive, do you have similar video for ISIS?
@ 1:18:47 Routers are interconnected with a switch , My question is how can other routers know the lsa or lsd as switch canot forward layer 3 traffic and LSA and LSD are layer 3 ???
Yes indeed! We usually have special offers for those who attend our live events. The next live event is on 9/28/22. You can register here: kwtrain.com/cyber Also, yes, you have lifetime access to your purchases. I hope that helps, and I wish you all the best in your studies!
I appreciate your selfless nature. Sharing knowledge without expecting anything.....

To this day, still the best OSPF deep dive. I revisit this session to remind myself of the concept.
Kevin Wallace always brings such a positive and enthusiastic vibe. Thank you for being an awesome teacher

Mr. Kevin, the beauty of your videos is you are giving them a human face.
Love the way you teach and how you put your perspective into layman's term in order for us to understand ospf better.

There doesn't get anyone better IMHO at explaining the fundamentals. Always great work Kevin!
The best explanation about complex topics... thank you sir. You keep me interested all the way.
Kevin is so good at explaining and giving examples. Very clear and very informative video. I understand LSA types now, Thank you so much Kevin. You're the best
You are such a great Teacher and a big Blessing to us. Thank you for the significant effort. God Bless you and your whole family.
Thank you so much for this refresher on OSPF. I hope you and your family are safe and well after that tornado.
Thanks very much. We are all safe, and I appreciate your concern.
Outstanding content!
I never get tired to see Kevin's lessons.
Super good coverage! Thank you for sharing your knowledge with us. The way you present things shows your passion and the joy of teaching! Keep up the great job!
Best video and what an explanation Now OSPF looks easy !!!!
Thanks Kevin! Needed a refresher, and this was a very clear and comprehensive overview.
Awesome deep dive ospf section. Would be great to have DMVPN deep dive (phase 1,2,3) as as well.
It couldn't be more amazing than this. Thank you so much. Hands down one of the most beneficial piece of knowledge I've ever received.
Thank you very much for the video. I have already seen a few videos on the subject, but none of them have covered OSPF in such depth and accuracy.

Thanks for making this available Kevin. I attended the live session and it’s very useful to go over it all again as a refresher. Cheers.
Thank you Kevin for this generosity 🙏
Kevin, You are amazing. Thank you for this fantastic tutorial. It refreshed all my OSPF knowledge en added much more to it.
Thanks a lot for this amazing explanation.
The notes I took helped me a lot, especially the one related to the network command because it was confusing me. Not only with ospf but eigrp also.
How was this free? Thanks for another great video Kevin! Tried watching other videos but no one can hold my attention as well as you.
Get this man a Nobel Prize for Networking.
Thank you for this video i watched many videos about OSPF but i only learned better from this one
thank you very much sir, we are waiting another this type of video for bgp.
Kevin you are a legend. Thanks for all your AMAZING content ⭐⭐⭐⭐⭐
Thank you so much for explaining info that I found quite hard in such a simple and entertaining way. I am just starting my path into Network Security, and these videos are so much help :)
Wild, i just spent all week learning OSPF. Perfect timing. Happy Holidays my friend
Thanks a lot Kevin. Great OSPF deep dive. Can you please do BGP deep dive?
Great Video, explain all I need to know about OSPF!
Very in-depth content with detailed explanation!
Please build a discord server for this channel for discussion!!
🙏🏽
One of well structured deep dive I have attended.
What a great and well-produced video.. :)
Hello Kevin, thanks for the content, will you do a BGP deep dive? Thanks
Really helpful videos sir, these really helps to get concepts clear, i mean your way of teaching is awesome, very nice and informative videos, if you can make some advance Deep dive on BGP and IS-IS that would be great too.
Thank you again sir!!!
This was a great webinar as always, Thanks you very much for your time and effort
Thanks Kevin for ur efforts...highly appreciable!
Excellent tutorial once again. please indicated summarization for IPv4 and IPV6 too. In addition would love to see the same thing in EIGRP too please.
I wish that this was translated to my language(tagalog) for better understanding. Superb explanation. Thank you.
Many thanks Kevin!! It was a great video!!
It's my first deep dive of your videos!
Apendi muito com o seu vídeo. Excelente vídeo. Muito obrigado e parabéns!
You`re an inspiration Kevin - thanks for the video and shared knowledge
Thanks Kevin for your informative videos. They help me to go for the ENCOR exam :)

Thanks so much for the Deep Dive videos! I think they are super helpful to understand these topics more clearly. Awesome awesome vids!!! 🤩
Thank you Kevin. from Phillipines

Great content by Kevin Wallace
Thank you Kevin, great explanation as always! Studying most of the CCNP topics with your amazing videos
Thank you, very helpful tutorial
I have question
What is the difference between using prefix list and access list?
Thank you for time and most helpful content!

The great news is I did a BGP Deep Dive earlier this year.

@@kwallaceccie thank you. I didn't see it.
I'll look to be ready for my contest! Even if it will add some hours of video in my schedule haha.
Thanks much! Could you please make session on BGP protocol as well? Thanks

Thanks, can you plan also to do deepdive for BGP. Thanks again
What an awesome session! Thank you so much for this tutorial!
Thank you so much Kevin! much appreciated!
Thank you for this great video. I am wondering if Hello is a packet or a protocol. You mentioned it as a protocol.
Thank you for this awesome training! Just an opinion, maybe next time turning on logs would help to better understand topics. Again, thank you anyway!
Hi Kevin.... As usual a great video from you. It would be great if you can make a similar video for BGP.... "DEEP DIVE BGP" as well..... thanks for the knowledge you share.
Thankyou sooo much sir I missed it yesterday thanks for the update sir.
Thanks Mr. Wallace.
you are the best, please also more videos on devnet?
Great explanation! Any chance we can get the slides please?
Hi Kevin
Is it possible to get the powerpoint you have made? It is so Awesome!
I love your content sir!! but i always had one question in my mind, why area 0 is only called as backbone area , why not area 1 or any? and whats the main role of backbone area?
Thanks !!

Thank you ♥
Does DMVPN with OSPF still elect DR and BDR ?
Thank you.
The traditional way ipv6 ospf configuration doesn't support VRFs. (CISCO 3800)
Ospf troubleshooting please
where can i find the slides sir?
Big thanks!
You are the best 👌 thank you
Thank you
Thanks i very enjoy thé topic
hey kevin , what is secret behind always so enthusiastic and energetic
No secret. Just genuinely loving the topics being discussed. All the best in your studies!
