You know the intro to each video? It's not the same recording, it's a fresh Jeremy every time.
The most fascinating fact I've heard this whole month probably.
I need more MaxwellChess DotCom comments!
Jeremy! Thank you so much! Your videos are so helpful!
Our teacher gave us a test today, which was about IPv4/6, DHCP and subnetting using VLSM. Thanks to you I got a 85% score and grade 5- (the best grade in my country is 6) and it was the best score in my class. This teacher is very strict so it's hard to get a good grade on his lessons.
Thank you again! I can't thank you enough!
Good teaching skills, fantastic visual diagrams, easy to understand language and the most importantly huge amount of hard work. I really appreciate all of it. Thank you Jeremy for everything you have taught me.

Taking a break from studying CCNA for a while to pursue a masters but I'm excited that the series will be even longer by the time I can get back to it! Keep it up Jeremy
Good luck with the masters! Maybe my course will finally be done by the time you return :)
Please stop bragging, seen your comments too many times now.
i'm taking a master's, preparing for the ccna and i also work a full time job (thankfully i work from home) and i have a family. it's entirely doable, but by no means simple
Hey Jeremy,
This video is awesome. explanations are very easy to understand. And I learned a lot about NDP functions. I finally found out the reason why Link-local next hop needs the exit interface specified. Thanks Jeremy. 😀
your videos boost a different kinda blood rush and confidence in me. thanx jeremy
You are my God in terms of teaching CCNA. I feel like you know exactly what make us difficult to understand and then explain them thoroughly.
Thank you :)
Congratulations! Best IPv6 content I have ever seen.
Sir, We always respect you for your great hard work. Your quality of work is highly admirable
Thank you :)
Thank you for going over the directly attached! I was wondering what I did wrong in day 32 lab since I was attempting it before watching the video, thank you for explaining it here!
Thanks Jeremy. You are doing best. Great course on TH-cam. Appreciating your great work.
Thank you :)
it's a very good lecture, very thorough, many thanks to Jeremy
Finally I complete the all 33 days and now I can continue with you, even though I took a long time but I'm very gratefull to take all my time, also the flashcard is very great tool. lot of thanks to you. great job what you are doing and you really make not clear point very easy and understandable.
Thanks for watching :)
Very clear content with just the right amount of detail.
We must atleast like and subscriber to thank Jeremy for the intelligent and hardwork he has done
Thank you very much sir! having reached to this part of this series, I feel like my understanding to the topics which are very new to me is getting smoother and smoother , your are the best teacher I had so far.
Thank you, Joy! I'm glad you like the course
Great course content! Thanks for all your work!
Thank you :)
The quizzes were great this time, I usually get them all right but the way these had specific key words made me miss a few and realize I need to take my time truly reading the question before jumping into an answer.
I always have problems understanding various networking topics but IPv6 is not of them anymore
Thanks to you ❤❤❤
Loved this video. Thanks again!
Thanks :)
Incredible lecture as always!
Thank you :)
Thanks for this new contribution. God bless you
Thank you :)
Terrific content. I am learning a lot from both your analytical approach to teaching as well as the labs and the flash cards. Could someone point me to the video in this series where it is explained how to study using tags? I thought it was the TCP and UDP lecture but I just went through that video again and can't find it. Thanks.
Technically RFC 5952 is RECOMMENDING that we follow that standardization.
Great videos
Took me a bit to understand. At 10:00 when talking about IPv6 solicited-node-multicast address, the ff02:11:f is a "fixed prefix", meaning the part in green will always be the same when dealing with IPv6 solicited-node-multicast address
Thanks jermy
I have not read all the comments, but regarding the RFC and Cisco products - what was not mentioned was the date the RFC was published compared to when the Cisco products showing varying hex values was made. Thus, if the RFC was published AFTER the Cisco product was made available, there is no way the Cisco product could properly show the hex values after, unless a software update for the Cisco product that might include the update was made available for the product.
Thanks Jeremy. That's a lot of info to get in on this ipv6 topic
Yes it is! Take it step by step ;)
@@JeremysITLab I do not know if you have some spare time to share a strategy of how to approach the study for ccna 200-301. Tks
Thank you Jeremy!!!
Thanks for watching :)
Thank you for uploading this useful playlist
Thanks for all your comments :)
this is gold
Thanks!
Thanks a lot man. That was great.
Thanks :)
wish you all the best ..
thank you
Thank you, all the best to you!
Hi jeremy, thank you for making such a great series of videos available for free, they are truly great!
I just want to point out that I believe you have mixed up the acronym "i.e." with "e.g.", e.g. (no pun intended) at 19:45 in this video.
thanks jeremy, i did pass my test because of u, regreats
thank you sir
Thank you sir for your great video.🙏🙏🙏
Thanks for watching :)
IPV6 like playing “addresses”! There are Addresses for everything. Imagine the concept of subnetting in IPV6, that would be crazy.
There is IPv6 subnetting! It's the exact same concept as in IPv4, just more bits!
@@JeremysITLab By the way, when subnetting with IPV6, only the 4 hex digits (subnet identifier) change to make the subnets? Thanks
Thanks Jeremy for another great lessons. The amount of information to remember for the CCNA it's......simply too much. Hope I will pass the exam. 🤔
Yeah there is indeed a lot to learn. Take your time, and always go back and review!
You are the King. 🙏🙏🙏
Thanks
very useful video...
top man! thank you.
Thank you!
Hi Jeremy, I realize you probably dont have much time to check comments these days, however im going to try anyway! I just want to thank you with the utmost sincerity because I have a fire inside that was lit from your work. Having been dabbling and exploring cellular networks for a couple years, mostly derived from Covid epidemic I was able to help families acheive at home study with schooling, work, etcetera. Many rural areas near me have no descent ISPs and I was able to help some people with cellular connections. While learning more about OSI model I realized how awesome you are after watching your channel and you have inspired so many including myself. We can never repay you for your dedication and time. My mind is set and I WILL PASS my CCNA amd I will contribute to your cause asap! Thankyou!
Thanks Jeremy. You are very great . Appreciating your wonderful great work.are you planning to make ccnp course?
I'll consider a CCNP course after I finish the CCNA course!
Waiting for the next ACL videos for syn my study knowledge with your videos.
ACL videos coming soon! :)
wow a lot in here, thanks man
Yeah there's a lot to learn, take your time!
Informative lecture
Thank you :)
Great videos Jeremy!! Would you happen to have a syllabus of whats to come?
Thanks! I don't have a complete schedule of the order of the upcoming videos, but incase you're not aware here's the CCNA exam topics list: www.cisco.com/c/dam/en_us/training-events/le31/le46/cln/marketing/exam-topics/200-301-CCNA.pdf
Very helpful course
Thank you :)
You are awesome
Thanks Mazin ;)
Thank you so much bro! I have been struggling with IPv6 for a while. You make it so simple
Thanks, glad to hear that :)
that note at 29:14 was so helpful , I was wondering why the route doesn't work even though everything seems fine thanks for your help Jeremy. It's one of those errors that are undetectable unless someone tells you it just won't work.
Yes I saw that and yet the Boson question in the quiz used that format in its additional information for the correct answer. Perhaps its ok to use just the interface for IPv6 default routes?
@@aussietx9403 "Directly attached static routes are candidates for insertion in the IPv6 routing table only if they refer to a valid IPv6 interface; that is, an interface that is both up and has IPv6 enabled on it."
Hello Jeremy , always appreciating your great work ! wish you all the best ..
Thank you, Samir :)
Jeremy, the name of RFC 5952 begins from the word "recommendation". So I suppose it's not strict rules, but recommendations only ;)
As I said in the video ;)
I heard so much hate about IPv6 before watching these videos, but after watching these 3 parts I honestly feel like IPv6 is actually pretty awesome, and NDP seems way cooler than ARP
Glad you like it! I'm a fan of IPv6 myself, didn't get to actually use it in my job unfortunately.
who is hating? ive only ever heard good things
Thank you so much Mr Jeremy for this great course. it really helped me a lot as a beginner.
can you please give us access to the course slides.Thanx again.
Thank you for your comment :)
Sorry, I don't provide the slides
thanks anyway.
I never thought i would grasp ipv6 until now. Would you possibly look at making a video extending on it, even if not part of CCNA ?
Currently this course is taking up all my time, but after I might! IPv6 is quite interesting.
@@JeremysITLab understand entirely. Big fan of your work anyway
When or why would you use a recursive ipv6 host route?
Nice,sir
Thanks :)
Thanks alot Jeremy. Your vedio is fantastic. Before this vedio I tried to look for the topics I need by other channels, but I couldn‘t understand every thing. Your vedios are very informative und easy to understand. God bless you. I’m looking forward for the next ones.
Thank you :)
Hi @Jeremy,
14:33 how does it know the unicast address(expect when you don't ping) ? Is it done by RS/RA ?
be blessed
Thank you!
I would like to thank you about your effort.
This channel is one of the best explanation course in my opinion.
Some lessons that I didn't understand like EIGRB, OSPF.
Are explained so clearly with no ambuguity.
I hope you will do course about cybesecrurity.❤❤
best
since IPV6 uses NS algorithim to determine dest mac address for NDP..is it possible to ping a device in different VLAN on the same physical switch if they share the same subnet?
are there more videos available in your ITlab ? when do you think to complete all the CCNA videos ? Many thanks for your great help
I'll complete the course next year, not sure when.
Great video Jeremy!...quick question...owing to the advantages that IPv6 has with NDP (MAC address discovery of devices) over ARP, will Spanning Tree protocol still need to be configured?
Yep, spanning tree is still necessary. IPv6 doesn’t fix the problem of Layer 2 loops.
@@JeremysITLab thanks for the feedback!
Hi Jeremy, i know this might be a bit to late to ask, but i am studying for my ccna and i am still new but for quiz question 4 i understand why fully specified is correct but why is the second option network and not (d) directly attached, being that the next hop address is a link local address ?
You do it great ! Jeremy. I am waiting for Frame Relay, NAT and ACLs
Won't be covering frame relay, but NAT and ACLs are coming up soon!
Isn't frame relay being discontinued by ISP these days?
Very impressive lectures on IPv6, .demystified the subject for me. Thank you so much.
Thanks Dave, glad to hear it :)
do we need to know how to convert local link to solicited node multicast address and then to multicast mac address is that part of the test
Thanks Jeremy! I just passed my CCNA exam.
Awesome, congrats!!
@@JeremysITLab Thanks! I really like your detailed explanation for every topic.
@@vincere7364 congrats . whats your advidse for others that study now to get ready for exam?
@@Hesam.Javdani Study the concept of each topic that is the key to pass the exam. Also try to answer simulation examination. And a little bit of LABs
@@vincere7364 Thanks
i got the boson bonus quiz question right without guessing it. i'm so elated
Well done!
For 14:28 how does a Router get a Unicast address and solicited-node multicast address if ping isn’t used/typed?
You should put your Teachable Site here so that people can know that they can videos ahead and support you.
Good idea, I'll add it to the description later!
I don't understand, Jeremy, you told me that the CALL is used for NDP but I see that it was a GUA to the requested multicast node address.????
does anyone know if Cisco has since started to use only lower-case characters for the IPv6 addresses? (The video is a few years old, so I'm not sure if they have since adapted to the RFC or are still "not following" it^^)
something weird for me i noticed regarding link local next hop config in packet tracer -- same error with needing an interface for next hop, however g0/0 did not work, using the question mark i realized i had to spell out GigabitEthernet for it to recognize the command. just a packet tracer thing?
Do the videos on port security.
I will cover all CCNA exam topics.
thanks Jeremy was just about to ask when you were gona post day 33,
The current schedule is a new video every Tuesday ;)
thanks in advance@@JeremysITLab
Heyhey Jeremy! 👋 Thank you for this great series! It is an immense help for my CCNA preparations. 🙏 One question: Why does neighbor solicitation uses the solicited-node multicast address as dst ip and not simply the unicast address of the target? Wouldn't it have the same effect? Thanks in advance!
That's what you get for thanking him in advance :P
The point of the solicited node multicast address is that the router can send the packet to the multicast address rather than broadcasting the packet to all devices on the network.
Even if you knew the unicast address, you still have no idea which device that address belongs to, therefore you would have to broadcast the NS out.
to this point, ipv6 stuff was the hardest to learn for me.
So, DAD let's each device know it's unique. Aw. :3
can you tell me what is the passing mark for CCNA and how it is calculated?
thanks
Thanks, Jemery, for the RS and RA, I wonder why is their multicast address different (all routers and all nodes)? Why can't they be the same?
Some messages are router-specific. If there is same multicast address, then full network (with switches and PCs) will be flooded and local network might feel congested.
if the ipv6 address is randomly generated for a host and not by using burned in mac addresses with eui-64, then theoretically you could have two identical ip addresses on a single network. how does ipv6 ensure this doesn't happen? edit : nevermind I just saw the next slide about DAD.
Question for Jeremy or any expert: Let's say router 1 (for example) is connected to router 2. If router 2's IPv6 address is used to generate the Solicited-Node Multicast address for router 1 to send out to router 2, in order to discover router 2's MAC address, then why not just use router 2's global unicast or link local IPv6 address instead of the Solicited-Node address, since it needs one of those addresses to generate the Solicited-Node address anyways? There doesn't seem to be a point in creating the Solicited-Node address. It is classified as a multicast address, but it's meant to reach only one interface. So why not just use the unicast IPv6 address of the interface?
Last question (for Jeremy or anyone that can answer): You stated at 14:24 in the video that R1 knows R2's Solicited-Node address because you typed in the 'Ping' command. What if you weren't pinging that address, and traffic was just being forwarded through R2? How would R1 initially know R2's Solicited-Node address? Would R1 just get it from a previous router advertisement received from R2, thus having that info in its routing table?
I hope this all makes sense. Thank you for any/all answers.
There is website that represent free dumps for the ccna exam?
Great As usual Jeremy!
But
When you said that directly attached static route won't work on ethernet you mean ethernet in general or won't work ethernet but will work on FastEthernet and GigaEthernet?
It won't work on ethernet in general, regardless of the speed
Amazing videos Jeremy! Your work is extraordinary! Is there any video about SLAAC with stateless DCHP server and stateful DHCP server?
please may you consider making VOIP Configuration, we would have appreciated thanks
Some very basic VOIP concepts are on the CCNA, I'll cover those
Hi Jeremy, I have a question about the BISON practice question
In the 1st paragraph of the explanation, "you can issue the ipv6 route ::/0 gigabeitethernet 0/1 command on Router C to create a default gateway".
As you said before ipv6 routes cannot use directly attached static route on Ethernet interface, so isn't the explanation incorrect? Thanks :)
Hmm Yes I think you're right about that! They update the exams often to fix small errors like that, I'll see if it has been fixed.
Are the router solicitation and advertisement messages automatically sent when we enable ipv6 via (ipv6 unicast-routing) or (ipv6 enable commands) on the device
'ipv6 unicast-routing' won't do it since it doesn't enable IPv6 on an interface, but 'ipv6 enable' on an interface will cause them to be sent automatically
In the Boson ExSim explanation they say:
-"you can issue the *ipv6 route 2001:db8:1::/64 2001:db8:2::/64* command on RouterC to create a static route to the 2001:db8:1::/64 network".
But shouldn't the next-hop part of the command be "2001:db8:2::1" instead of "2001:db8:2::/64"?
Is this an error? Or am I missing something? How can the whole network be the next-hop instead of RouterB's ::1 interface it has to go to to reach the 2001:db8:1::/64 network?
Fairly certain it's an error. I noticed this too and having the next hop set to it's own network address makes no sense.
Hi Jeremy do you take students for live classes?
Sorry, I don't do live classes.
even though i am trying to understand ,its hard for me to understand these ipv6 concepts jeremy
Try googling for some other resources, they might help you understand!
