I'm being honest with you, I'm learning CCNA course with a lot of money in outside and I didn't understand what my teacher said to me. But for you, your explainations and teaching ways are way better than my outside teacher. You're the best teacher for me. Thank for your video. Keep going, I'm alway your fan. The best RU-vid Channel for me.

i was searching lots of material for CCNA. since the day i got this channel i am just flowing with your contents. such a great explanation from ground level. even i am reading your content ignoring my hunger and food. thank you so much for these efforts .
Can you believe that I got hired for an internship without even having a CCNA yet because of this Course? Basically the recruiter asked me what I was currently studying and I said: VLANs, explaining what I learned from this videos. Thank you so much Jeremy
These are still the best CCNA videos on RU-vid. So many people will be able to learn a lot from these videos and would definitely pass the exam. Thanks a lot Jeremy !
Man, I really hope everyone who is studying for the CCNA have the opportunity to look at your videos and I'm sure spreading out the word! Always above and beyond, thanks Jeremy!
In my country we don't speak english but the way you are teaching with your simple english i feel like am english man,for sure am enjoying CCNA with you
As always, brilliant content. It's the teaching that is excellent, more than anything. And even though I already know this, I still took time to watch. Just one thing I noted. Thank you Jeremy
jermy i'm in love with the course. its the best ! now i have a question for everybody see this comment : maybe do you do some summaries or some bullets or some more detailed flashcards and can share it? i am very anxious because i know that videos are not enough for me , and i need summary/bullets of each great video here so i can quick review if i forget.
i have mixed Feelings with this Learn Series and I want to share them with u: PRO's: 1) I agree with the other people here, you have a great talent to explain topics detailed, and structured step by step. 2.) Most of all I like it how you go into all the possibilities that can happen, without ommitting anything and without leaving open questions in the room. I paid 2 courses on other plattforms and both are fast in generalizing topics and leaving open questions (which all will explained in later sektions so you have to study 2months longer to get the answer) 3.) Thanks for the plenty amount of learning material such as labs and flashcards. although i think that many flashcards are not nessesary for the test. for example i spend 2 weeks of learning this IEEE standards, but in my last Test their was not a Single question about this. (could be random). I failed the test, partly because i only got 6 weeks before test the instruction to learn from my supervisor, only preparing with labs, vids, flashcards.. with 602/1000 points (825 to pass), so a tip to all.. its not a good idea to spend to much time like 2 weeks on memorizing flashcards. My other co-workers recommended me to learn with dumbs (in 2 weeks is the next exam), as 2 people pass the exam with that with about 920/1000 points. Nevertheless i think its important to learn also with this courses to get the understanding of networking fundamentals. CON: its the shadowside of 2.) because you go in so detailed, you take more time in making more videos, thats why we are by now only finished with vlans, stp, vtp.. and havent covered topics like dynamic routing protocols, dynamic trunk interfaces, IPv6, security, etc. which are all very common in the test. Because of this I was forced to buy courses in the internet as well. 4.) because you share that course for free, the videos are peppered with lots of advertisement which repeatedly interrupt the concentratrion and focus on the topic. Its like swipping news on my smartphone while an important lesson. To be honest I would prefer it when you would demand a fee instead of advertising. I would buy thst course nontheless, because of first mentioned reasons. to all i would recommend to preper at least 2 months of study before enter exam
Hi! Thanks for your detailed feedback. As for the cons: I really do want to make videos more quickly, but I work full-time from Monday to Friday and can only make videos in my spare time on weekends, so I can't really increase the speed. As for the ads on RU-vid, understood! I will look into putting the course on Udemy or somewhere else.
Thank you, I was getting nervous when you would release another video. I hope you are doing well. Again I want to thank you for spending the time to create this video series, me and everyone else who are watching them really do appreciate the time you are taken to create them. Thank you
0:19 VLAN (Virtual Local Area Networks) 0:41 Things we'll cover 1:27 What is a LAN? 2:30 LANs/ Broadcast Domains 4:38 What is a VLAN? 13:05 VLAN Configuration 17:51 Things we covered 19:12 QUIZ
I am low-key anxious that I am about to finish these amazing videos and I'll have to wait for the weekly uploads, lol! All in all, they are all worth the wait. Keep it up Jeremy! Arigatou!
Wonderful training lessons so far. I wish you are able to upload some lessons on new ccna topics such as automation, programmability & wireless etc.... Thanks
You definitely are the best RU-vidr I've seen that is making this Course so simple to understand. I'm curious how far are we from reaching the very end ?
Same here! I've tried studying other stuff this way and was never able to keep up, but IDK why the way he teaches makes it way easier and makes you keep up
I know it's only part 1 of VLans, but I aced the quiz first try. I thought I was making a big leap with question 5 but I got it correct trying to justify it, so far I understood it greatly thanks Jeremy
Thank you! The routers will still receive and process broadcast packets (for example, if the broadcast message is an ARP request from a PC to learn the router's MAC address, it will respond to that broadcast message). But they won't forward them.
the VLAN graphics help so much. No wonder people struggle with traditional teachers teaching networking, they just talk about it expecting you to understand them. You need color coded graphics to explain something very abstract like VLANs. Thank you Jeremy!
Hi Jeremy - i just want to check my understanding of broadcast messages. I'm looking at question 4 on day 16 - the answers you give is three devices which was my imediate thought too.. however, i remember you saying in a previous days learning that a broadcast is sent of of all interfaces except the interface it was received on. That being the case am I correct in thinking, if PC3 sent the broadcast it wouldnt be received back from the switch by PC3, so only two devices would actually receive the broadcast? I'm really enjoying your course. Its by far the best, most comprehensive and well thought out i've found - I really appreciate the hard work you have put in to making this and will be making a donaion my friend :)
When discussing Broadcast Domains, you say that a point-to-point connection between routers is a broadcast domain. Is it still a broadcast domain if the routers were configured using VLSM and the subnet mask for that subnet is set to /30? When the subnet mask is /30 there are only 2 addresses to be used for each device, there is no network address or broadcast address. Does the lack of an assigned broadcast address mean it is not a broadcast domain?
There are two broadcast address types, the IP address broadcast address and a Layer 2 Broadcast MAC address. So even though they technically are void of a dedicated IP Broadcast address, theoretically frames of Destination Address type FFFF.FFFF.FFFF will still be received by either router if either one is the source of that frame. However, as you mentioned they hardly will generate this kind of traffic because of the P2P topology. But they are still considered to be in the same broadcast domain nonetheless because of this.
Question: broadcast domain is when a device sends a broadcast frame with destination mac address of all Fs,. Routers doesn t send mac address broadcast with all Fs, then why they are broadcast domain?
I've been using VLANs since March or so (with OpenWRT), but didn't know much about the background like you explained in the beginning, like how things can be passed on without going through the router without VLANs, and about layers etc. Thank you !!!
MAJOR IMPORTANT POINT: VLANS SEPARATE END HOSTS AT LAYER 2. despite operating at different broadcast domains. there's always going to be a question like this in the test: to relate VLAN with which OSI model layer
Love your videos ❤ I had a question regarding quiz question 5. The options mention values 3, 5, 8 and 10 but that is considering the fact the interfaces under g0 and one interface under g2 is not assigned to any other VLAN. Stating from the POV of the exam, shouldn't an option with value 7 exist? What I'm trying to ask is, we will be given the list of interfacs of the router first, right?
I don't follow your question...in the exam, you will be presented with a series of choices, and you have to select the correct answer from the available choices. The choices for quiz five could have been 3, 5, 8, 10, or 3, 5, 7, 8, 10, or 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, or any other number of choices. It doesn't matter: the correct answer is 8. You may or may not be given a list of interfaces - it depends on what information is necessary for you to answer the question. For quiz 5, the interfaces are irrelevant to the answer (the answer is 8 regardless of the interface configurations) so you probably wouldn't be given a list.
Hi Jeremy, i have heard a network admin say that unnecessary broadcast traffic can still happen even when you've configured VLANs on a switch and a trunk port to allow specific Vlans. How true is this?
In quiz question 4, as u asked how many devices will receive a broadcast message - i think it is 2, because the device which sent would not receive a broadcast message, only the router amd the other host in the network. Please correct me if I'm wrong
Here's what I said in the explanation: 'First of all, the switch will receive it, then it will send it out all interfaces in VLAN20, so the router and the other PC in VLAN20, making a total of 3 devices.' So, I included the switch in the count!
What about having every computer ping the switch to build the mac address table, without a destinations address, someway to not flood, even if incurring some error or denied request, every x minutes to stave off the address table lifetime???
Thank you so much Jeremy for this magnificent course. I'm very grateful. How can I join the JCNP-group, I don't see the join button under the video. Thanks again.
The join button should be under the video...if it's not I'm not sure the problem. Perhaps it's not available in some countries? Anyway, thank you so much for wanting to support the channel.
BRAH!!! just bought david brombel ccna course .....nO NO NO.....i wanted a diff perspective.....good info ...but brah....urs are still my fav & go to.....Neil's course is actually better imho....compared to davs....it was sale ...lol......i just want to crush that exam!!
Thank you so much. Really your doing really Great, I am following you, could you please share syllabus copy your following.. So i can make make notes, and writing down to my goal.. Thanks a lots
I am a bit confused on the naming scheme of the vlans. Does it have to be called VLAN10, VLAN 20, VLAN 30, etc. or could it be named something else? I assumed they were named VLAN10, 20, 30 for simplistic reasons?
This video just covers access ports, you'll also need to learn how to configure trunk ports (that will be in day 17's video), so it's not quite enough information yet!
The 3 subnets has different broadcast address like 192.168.1.0/26 broadcast address is 192.168.1.63, 192.168.1.64/26 broadcast address is 192.168.1.127 and 192.168.1.128/26 broadcast address is 192.168.1.191. My question is how the 3 subnets are in same broadcast domain even though the have different broadcast address?? Broadcast domain and broadcast address are not related??
There are two types of Broadcast addresses: you have identified one of them. The IP Broadcast address. The other type is the Layer 2 Broadcast Addresses (FFFF.FFFF.FFFF). A switch forwards these broadcast addresses to all devices in the same Broadcast Domain - even if they are in different subnets. This is where VLAN comes in, to break up the Broadcast Domain of a LAN using multiple VLANs.
