ERRATA: At 21:33 I mention /28 masks regarding R1's G0/0 and G1/0 interfaces. Should have said /30 as written on the diagram and the command output.

These videos are actually better than a lot of the paid ones I've watched.

I encourage EVERYONE to go buy the official course!!! I enrolled in an university that offers Cisco’s courses before i found these videos. The professor at the college institution, in charge of the lectures is NOT on par with Mr. Jeremy. I am not exaggerating! During my studies as an electrical engineer, I have not encountered another person with such profound understanding of the concept, like Mr. Jeremy. I don’t know how the guy does it. Great communication skills and vast knowledge!!! Great job!

I passed my CCNA today. Special thanks to you for your video. I'm really grateful 🙏🙏🙏

Doing your lectures with screenshots to my iPad on Notability and writing down a lot of notes on Joplin in 2023 whilst having been working for some time in the telco-industry here in Finland, and just absolutely bravo Jeremy. What a treat these videos are.

[mohammadrahal]

what a comprehensive introduction to OSPF, amazing as usual Jeremy

[rotrose]

Your tutorials are legendary, you make the whole networking concept so clear that it does not only help us to pass CCNA,
but this series does have practical significance that I already use the concept you teach here to do real networking. I can not say enough thanks to you.

[muhammadjunaid]

Wow! This is called a perfect CCNA to Jeremy for putting complete effort.

[NetworkingwithHamza]

Excellent video series. Consistency is the key and it is the hardest thing to achieve. So many distractions are existing around us. I stopped this series almost 2 times but then came back with more passion. I am planning to finish till video 30, then print out all ANKI Flashcards ( I prefer traditional way to memorize stuff. I have converted Anki flashcards into a pdf file of 309 pages from day 1 to day 63) Then memorize all ANKI flashcards, do all the labs without watching any video (unless I stumble upon something or to verify if I have done the lab correctly) or using notes. Then continue again from Day 31. Day 45 to 63 will be easier for me as I have already completed Cisco CCST (Cybersecurity Pathway) on Netcad. Thank you so much Jeremy. I realized if merely watching these videos require so much consistency. How much effort was required for you to create this course. Salute sir.

[LynksysMD]

Thank you for this covering of OSPF. I've been working through Neil's Udemy class and its for the most part good but I had to try something else for his OSPF coverage and this has been exactly what I needed thank you Jeremy.

so far Jeremy is the best teacher I found in teaching network course online, really hope you can expend your teaching in firewall stuff.

[hashanbhushitha]

Clean information, well structured and on point.thank you jeremy you are a life saver.

[ranjanadissanayaka]

Hey Jeremy, thanks so much for making these videos and labs and flash cards available for free.
I used the flash cards for this video and it helped me a lot to understand and really remember the content. So thanks again.

[glenntembo]

Jeremy Jeremy! JJ oh man you have done it again, your lessons keep becoming sweeter and sweeter. Detailed, no stone left un-turned. Thanks for the theory. Haha unfortunately got one quiz question right. It will all sink eventually. Thumbs-up dude. You the man. Can't wait for the lump some notes from video 24 or 25. I subscribed (smiling!)

[pauljennings]

Very Impressed with these videos. I'm using as a refresher before starting study for the CCNP and i'm finding them great. Thanks!

[monetka]

Jeremy, I would like to confess, I completely fall in love with your videos, such a great job! Thank you many - many times! 🙏🙏🙏🙏🙏🙏

[fernandotorres]

great explanations, I just recently landed a job as a NOC technician for an ISP and your course has definitely helped me get prepared for my ccna and feel more confident about my soon to start job, keep up the good work

[omidsupply]

Wow! One of the best and elaborated clip along with simulation lab that is a great lead to CCNA vendor test. I highly recommend. I can't thank you enough! 100% 💯💯⭐🌟💫🌟⭐
