Enjoy the training!
I appreciate your selfless nature. Sharing knowledge without expecting anything.....
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.
Kevin Wallace always brings such a positive and enthusiastic vibe. Thank you for being an awesome teacher

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.
I really appreciate these training tutorials. They serve as an excellent refresher. I look forward to more in the future.
To this day, still the best OSPF deep dive. I revisit this session to remind myself of the concept.
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.
Hi Kevin. Just found your channel during my CCNA study and want to say thanks for your deep dives. I find your conversational style great for reviewing subjects I've already covered with more formal courses and expanding on the baseline information so my understanding is more contextual. Fantastic videos. Keep it up. Thanks again, from down under!
Mr. Kevin, the beauty of your videos is you are giving them a human face.
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.
Hi Sir, thank you so much for this tutorial. I learnt how to configure ospfv3 and authentication. Chris from south Africa 🌍.
Hi Kevin, thank you for your time with such clear explanation. Your explanation is always helpful for my studies. Thanks again.
Love the way you teach and how you put your perspective into layman's term in order for us to understand ospf better.
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 🙏🏼😊
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.
There doesn't get anyone better IMHO at explaining the fundamentals. Always great work Kevin!
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 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!
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!
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!
You are simply the best Mr Wallace !
Thank you
Kevin, I appreciate. I am doing the review to do ENARSI. Thank you
Wild, i just spent all week learning OSPF. Perfect timing. Happy Holidays my friend
I am just amazed how Kevin does it with ease . thanks Champ
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.
The best explanation about complex topics... thank you sir. You keep me interested all the way.
Thanks Kevin! Needed a refresher, and this was a very clear and comprehensive overview.
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
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.
I wish that this was translated to my language(tagalog) for better understanding. Superb explanation. Thank you.
Outstanding content!
I never get tired to see Kevin's lessons.
Awesome deep dive ospf section. Would be great to have DMVPN deep dive (phase 1,2,3) as as well.
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.
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 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 :)
Kevin, You are amazing. Thank you for this fantastic tutorial. It refreshed all my OSPF knowledge en added much more to it.
Best video and what an explanation Now OSPF looks easy !!!!
thank you very much sir, we are waiting another this type of video for bgp.
Very in-depth content with detailed explanation!
Please build a discord server for this channel for discussion!!
🙏🏽
Thank you for this video i watched many videos about OSPF but i only learned better from this one
Kevin you are a legend. Thanks for all your AMAZING content ⭐⭐⭐⭐⭐
Very nice explanation 🙂
What a great and well-produced video.. :)
Thanks a lot Kevin. Great OSPF deep dive. Can you please do BGP deep dive?
Many thanks Kevin!! It was a great video!!
It's my first deep dive of your videos!
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.
Great Video, explain all I need to know about OSPF!
Thank you Kevin for this generosity 🙏
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 ^^
The great news is I did a BGP Deep Dive earlier this year.
Here’s the link:

Hope you enjoy!
@@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.
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!!!
Thanks for this Kevin
Thanks so much for the Deep Dive videos! I think they are super helpful to understand these topics more clearly. Awesome awesome vids!!! 🤩
Thanks Kevin for your informative videos. They help me to go for the ENCOR exam :)
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?
This was a great webinar as always, Thanks you very much for your time and effort
Hello Kevin, thanks for the content, will you do a BGP deep dive? 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 Kevin, great explanation as always! Studying most of the CCNP topics with your amazing videos
One of well structured deep dive I have attended.
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.
thank you so much for this masterpiece
Thanks Kevin for ur efforts...highly appreciable!
You`re an inspiration Kevin - thanks for the video and shared knowledge
Thank you Kevin. from Phillipines
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?
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!
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
Great content by Kevin Wallace
Thank you for this great video. I am wondering if Hello is a packet or a protocol. You mentioned it as a protocol.
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.
Thank you for time and most helpful content!
Thank you, very helpful tutorial
I have question
What is the difference between using prefix list and access list?
Excellent ... well done ..
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!
Thanks Mr. Wallace.
Thank you so much Kevin! much appreciated!
you are the best, please also more videos on devnet?
Thanks much! Could you please make session on BGP protocol as well? Thanks
What an awesome session! Thank you so much for this tutorial!
Thankyou sooo much sir I missed it yesterday thanks for the update sir.
Thanks, can you plan also to do deepdive for BGP. Thanks again
Apendi muito com o seu vídeo. Excelente vídeo. Muito obrigado e parabéns!
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.
Thank you.
@ 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 ???
awesome video!!!
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 !!
Thanks for this!
Hi Kevin
