ERRATA:
Typo at 16:00: “BackboneFast allows SW3 to expire the *made* age timers...” should be ”expire the *max* age timers...”
At 37:15, SW1's port connected to the PC should be G0/3, not G0/0.
Don't you think, that SW3's G0/1 should be the root port and not G0/2? They have same root cost, same neighbour BPDU, but G0/1 has lower port ID giving it advantage to become root over G0/2

@@JeremysITLab Oh wow!! i didn't knew that, that makes a lot of sense now. Thanks Jeremy for the reply and info, you are the best.
There is on one side courses/books that briefly tell you about some concepts, tell you what to remember and give definitions to learn by heart, making it really boring, and on the other side Jeremy's lessons that make you really understand all these concepts in detail and making it interesting at the same time!
Can you believe that the Official Cert Guide Library from Cisco Press is not even mentioning non-designated ports, not talking about which port roles send/receive BPDUs, and, what I consider the worst: giving extremely poor explanations about path costs, alternate ports, and backup ports (they are just mentioned)?
Thank you, for real, for all this time you invested in us, making it so interesting!
Least we can do. Please do not forget to like all the videos
Been liking since #1
Jeremy, i have taken 3 times CCNA courses since version 4.0. but you are by far the best teacher. Really clear concepts and great methodology and examples. Really, thank you for sharing your knowledge and effort on this course.I hope you can finish all the topics!
Thank you Jorge :)
Hello from Russia, Jeremy) Thank you for your incredible help in preparing for the CCNA)
Hello! Спасибо! :)
Hi snake
always with you, jeremy
Great job Jeremy, keep up the good work.
I had already done the CBT Nuggets videos and read Todd Lammle books which are all great, but left me a little iffy on some concepts, after watching your videos I am finally understanding everything that I missed or was unsure about! Thank you so much, I was about to give up after not understanding it well from those other two sources.
Minute 2:27 "it was created in 1985" why does the doc from Back to the future come to my mind now?👀☝️... Thanks Jeremy! Bonjour du Mexique !👍🏻👍🏻👏👏🇲🇽🇲🇽
Thansk Renato ;)
Great videos, I am currently taking CCNA2, your videos are a great addition to my course.
Jeremy you are a legend, Im picking this all up. Thanks
Although you said that you don't have to much time for the videos, keep it going to make the rest of the videos early, you are such a good teacher.
I'm studying CCNA from your videos.
Thank you! I'll do my best.
very good lecture, thorough, clear, especially quiz questions are very helpful
Thank you Jeremy. Your videos are awesome and very informative!!!
Thank you!
Just completed the lectures, excited to work on the labs then practices tests! Great work putting this together!
Well done! Just a heads up, the course isn't finished yet, I've only covered about 50% of the topics!
Thank you so much for this...i love the labs and I know the more I do them, the better off I'll be...I'm learning a lot with the labs and that's something that distinguishes between this channel and others. Keep up the great work!!!!
Thanks Alina!
from kenya am self teaching and all is well @ day 22 .bless you jeremy!
After I had watched your STP 1, 2 and this one, I really felt regret for missing your channel to watch and learn from you. Thanks a lot for your kind contribution. with Best Regards,
Hey Jeremy, i wanted to thank you for all your work that you have been doing with these courses, they are very lucrative, smart and professionally made.
In addition to the free youtube course, i've bought your complete CCNA course on your website to support you, but also to the addition of PDF slides to use as a refresher/notes whenever i feel like i forgot some details :)
Again, thank you for your work, never stop learning!
Regards, Tamerlan.
I was having some confusion with the RSTP and after having watched your video, everything became crystal clear.. great video and very well implemented with examples at the right time plus the Boson exam sim is a great bonus.. Can't thank you enough.. looking forward to your next CCNA videos.. cheers!
Brilliant session, very clear and easy to be understood.
Thanks so much Jeremy :)
I gotta say, you def. made this easier by teaching us the parts of STP that may not be on the exam, too. I found myself struggling to grasp Classic STP for a few days. But after some studying + the flashcards and lab, I mostly got it down. Now, learning RSTP feels like a breeze. That's "wax on, wax off" type stuff. Markings of a GREAT teacher. 😄
So nicely prepared.
Finally i managed to solve the quiz on my own!!! yeah baby!
Quiz 4 was so good, thanks jeremy!
Watched the videos on stp topic 3 times 😀
Thanks Jeremy👍
Thank you so much for this course!
My pleasure!
Excellent Jeremy! Thank you!
Thanks Neil!
Such a great explanation.. I always waiting for the next video.
Thank you!
I love very much that course, i am learning step by step, but i am learning very well because Jeremy teaches very good, is very easy to learn with him.
Hey J! This video is awesome, very didactic. My best wishes for you. From Amazonia, but now I live in Portugal.
Thank you, glad you like it!
All of your contents were very informative and in detail that I have ever watched. Thank you very much for sharing your great knowledge for free
Thank you :)
Dear Jeremy,
Please forgive me for not watching your videos for a while now. I've been using the Boson Simlab for practice and have not be in on UA-cam. You're still awesome.
Your friend you've never met,
Timmy Tim McTimson
No worries, watch at your own pace ;) Glad you like them!
hello from jordan jeremy thanks alot for these videos i am starting understanding ccna much better than i took it that corse in my country gad blessed you i hope
Finally feel to be able to get out the long, dark STP tunnel to move forward,Thank you very much.
Hey bud, your videos are excellent and beyond depth than any instructor. Keep up the good work! I would be happy to even buy course if you go for CCNP videos :) Also,I need to ask tool that you use for diagrams in your video. Can you share name please?
I just use LibreOffice Impress, which is basically a free version of powerpoint. If you have powerpoint, that's just as good :)
It took me some time to understand this, but is so clear now. i had concept maps of this.
Eyyyy I finally Finished The Video with full understanding .... thank you :D
Nice ;)
me to :)
Great stuff i got the quiz questions right and understand. Cant wait till you finish the course ill miss ya when im studying vol 2 via textbook. Monetary support incoming
Thanks Jeremy! Glad you're liking the course ;)
That's a lot of info to digest. Thanks, Jeremy
Yes it is! Take your time to absorb it all, no rush.
@@JeremysITLab what do yo advise to not forget all this details when you’re ahead like in future chapters because sometimes i feel I kind of forgot some details as weeks pass over need some mechanism to better retain information in my brain,.
Hi Jeremy. I started to read the official documentation for CCNA, before knowing about this course, but I didn't understand 100% the STP. I was a bit frustrated, but then I discovered your course. I am really happy, you are a great teacher and explain the topics in a simple way that it's easy to understand. Now, I first watch your video and practice with labs and then I read the official documentation. It changed my world. Thanks so much for this course !!!
Thank you Francesco, I'm glad my videos helped you understand!
Thank you very much for the videos. I complete the quiz 4 without mistakes :)
I got Quiz 4 wrong the first time then watched the entire video again with playback speed 1.5x and then finally understood how to assign the port roles properly, thank you!
Hi Jeremy. Thanks for the awesome videos. You have a great teaching style. How many videos are you planning on making for this series?
I think it will be about 50 days in total, so 90 to 100 videos.
Thx Jeremy for the video
01:00 am at night I was doing this video having on my Krakens. My wife was sleeping in the next room. I was looking for the last question: and I was like: It is Port fast. Port fast. And my wife came up: „Okay, ok.“ We hear you, its c portfast. »Let me sleep.«
I just need to make practice on Root selection, if its designated or root etc. Thanks Jeremy
Keep it up!!! I am planning to take the ccna exam after this quarantine
Good luck! Let me know your result after you take it.
me too. you are my first teacher of ccna and i learned a lot from you. thank you so much for your teaching sir, Jeremy.
I hope you did well on the test
thank you very much for that effort
THANK YOU SO MUCH JEREMY
Thank you Sadun!
I must be Rapid SPT myself, because I'm basically in a "Blocking, Listening and Disabled states are combined, and the Listening state is not used" state every day at work.
More motivation for me to study and pass CCNA in hopes of landing a better job.
If not for Jeremy I'd probably have given up already.
Hey Sir, I found your explaination the best in youtube and i have went through all of yours CCNA series . May i ask do u have series for CCNP?
16:53
maybe we should be allowed to use google on the test lol
A long video but very informative. thanks again
Agreed. STP is wearing on me.
Great video and explanation as always Jeremy. I'm actually going through my own online networking school and we've gone through a 6 week CCNA prep course to finish up the entire 6 month program. A couple questions, I know you said RSTP and Rapid PVST+ are interchangeable in this video, but I'm still confused as to which one you spent the majority of the time on. Was it Cisco's or IEEE's (I think it's Cisco's)? Also, in the course that I have gone through, my instructor has the Backup port as the port that will assume the Root port role if the current Root port fails, and the Alternate port as the port that will assume the Designated port role if the current Designated port becomes the Root port, or if the current Designated port fails. In this video, you have them the other way around. So which is it? Thank you in advance.
Thank you Jeremy.
Thanks for the comment, Stephen :)
Good, thank you so much!!!
Thanks mr Jeremy
THANK YOU VERY MUCH SIR ITS REALLY HELP ME LEARNING THIS SUBJECT
Thanks for watching ;)
Dear jeremy thankyou
Thanks for watching :)
just amazing 👍
Thank You Jeremy
Thank you :)
Thank u very much sir. i appreciate your work.
Thank you :)
I recommend Jeremy it lab as it provides best quality Cisco training material
Thank you! I'm glad :)
thank you a lot for this explanation, you realy know how to introduce the informations. I'm looking forward to take ccna exam after finish your course. I also use CCNA 200-301 Official Cert Guide, volume 1 and 2. I hope that it is enough to can pass the exam.
With my videos and those books, you'll definitely be able to pass!
@@JeremysITLab thanks again you gave me another push and more confident
Hi Jeremy,
Thanks for the awesome lesson!
Do you need to set up bpdu guard on the edge link in RSTP also? If you do, is it done in the same way as STP?
Thanks for the help.
Hi I would like to thank you for your CCNA videos and also the labs that you have provided for us to practice it's been really helpful, I was wondering can you make a video regarding WAN concepts and technologies and also QoS thank you very much.
Thank you! I'll cover those topics later in the course.
Hello from Philippines. You have a chance to change people life's by doing this free CCNA. Maraming Salamat
Thank you! 🇵🇭
all clear thank you sir
thank you
Wooow sir awesome teaching technique
Thank you ;)
I like summarizing things 👌👍☕
Hey Jeremy!
Got some questions about hubs :
- Can they be used with another cable than Fast Ethernet? (Can they even be used with FastEthernet cable? I've read that the maximum speed of a hub interface is 10 Mbps)
- If so, what happens when you connect FastEthernet cable on one side and Ethernet cable on the other side? what will be the root cost of a path like that?
great lecture.
Thank you :)
HI Jeremy, thank you for that excellent course.
I cant understand the difference between PortFast feature and Uplink feature ,
I understand that Portfast is a feature that I can use for access ports or ports that connect switches to Endhost ,,but also I can use it for trunk ports !!,so what it is the difference between these two features.
and another question ,we need the forward delay to prevent layer2 loops ,so why we are skipping that time by using Uplink feature , aren't we put the network in a danger when we doing that?
thank you very much Jeremy
🖤🖤🖤
Hello Jeremy. Thank you for your hard work. Will you please explain why portfast is called optional in STP, but called built-in to RSTP? You need to manually configure it in both protocols, so why isn't it considered optional in both? Thank you very much.
Thanks a lot Sir for your efforts, when often you publish new videos for the series ?
I publish a new video every week!
Crystal clear explanation as always, thank you so much!
Btw, I was wondering if you already have the whole course contents layout, could you share it with us? That would be great.
I really like how you did it, from OSI to subnetting, static routing, VLSM, VLAN, DTP/VTP, STP, etc. Other courses that I took before are different where it goes from OSI, subnetting to TCP/UDP, DHCP, NAT, etc. More theories than actually creating and working with networks.
Having the course roadmap will allow us to study on our own while waiting for the next upload. What do you think?
I don't have the exact order mapped out, I just know the general direction. I can tell you the next few topics though: EtherChannel, dynamic routing protocols (OSPF), first-hop redundancy protocols.
The best hero Jeremy
Thank you ;)
thank you soooo much jeremy, youre such a great guy! really appreciate your hard work. you didnt record all the other parts yet, didnt you? i would pay for them to get them earlier to finish your course as fast as possible as i have some free time now
I second that, I have purchased the Neil Anderson's course on Udemy and it doesn't compare to Jeremy's IT lab. I had to purchase it because I want to finish the course earlier and take the exam. If Jeremy would finish the course earlier than the end of the year (even if he makes it a paid course) I would definitely buy it without a second thought.
@@abdelrahmanelsherbiny8833 you already passed your exam?
@@MM-bm7wt No I am still studying, got half way through and I plan to take the exam in a month or so.
Sorry, I don't! Making these videos isn't my job so I don't have a lot of spare time to make them.
@@JeremysITLab ok thanks :) I have a question, do you think you already made the most difficult topics on ccna till now? Or are there topics remaining which aren't easy to understand? So I can compare if its worth taking another course for the rest you didn't made yet
Thanks!
Thanks so much for the tip! Sorry for the late reply, I just noticed this comment now. I appreciate your support :)
Videos well expressed
Hi Jeremy, a couple of points (only to add my humble input to the amazing videos you made).
1. Erratas should be permanently at the top of the comments. I've seen that in other videos but not on this one.
2. The RSTP costing drove me crazy... my Packet Tracer show the STP costings but I was using RSTP !... so I check on a GNS3 with real Cisco image, and the same STP costings !!??... then I found that there is a setting for 32 bit (instead of 16 bit) costing and that is how the switch shows the RSTP costing... I have not read all comments, perhaps this was already mentioned.
your teaching style is very attractive. we will be very glad if you give tutorial about following subject
6.0 Automation and Programmability
6.1 Explain how automation impacts network management
6.2 Compare traditional networks with controller-based networking
6.3 Describe controller-based and software defined architectures (overlay, underlay, and fabric)
6.3.a Separation of control plane and data plane
6.3.b North-bound and south-bound APIs
6.4 Compare traditional campus device management with Cisco DNA Center enabled device management
6.5 Describe characteristics of REST-based APIs (CRUD, HTTP verbs, and data encoding)
6.6 Recognize the capabilities of configuration management mechanisms Puppet, Chef, and Ansible
6.7 Interpret JSON encoded data
Thank you! This will be a complete course for the CCNA, so I will cover those topics later.
Hi Jeremy,
Thanks again for the excellent course on RPVST. To prepare the exam, practising with Boson EXSIM is enough or it is required to buy also Netsim ?
Thank you
Theo
You don't NEED either, but I think both are excellent and very useful tools. If you're going to buy just one, I recommend ExSim, because there aren't any free sources of good practice exams, but there are some free lab resources (although not at the same level as NetSim)
Sadly I'll take my exam before you finish the course but I am enjoying it so far.
Thanks, glad to hear that :)
Hello Jeremy, Loving the course so far. I am learning a lot, and I have one question for Quiz 4. Why did switch 3 select g0/2 to be its root bridge. Does the tie breaker go the the sender's port ID or the receivers bridge ID or am I mistaken in believing that g0/2 port ID is higher than g0/1. Thank you.
thank u so much...
Thanks for watching and leaving a comment :)
Thanks❤
So my network diagram I made was ALMOST exactly as shown at 38:45 with one exception: the G0/1 link on SW1 connecting to G0/2 on SW3, for which I had the Root and Alternate switched on interfaces G0/1 and G0/2 on SW3 switched around. When I made the determination that G0/1 on SW3 was root, I did so because of its interface number being lower than G0/2, but I don't understand why I got this wrong, as it was the only difference I saw between G0/1 and G0/2 on SW3 that would have made the determination for the root?
Hi Jeremy, first of all, thank you so much for your world-class educational videos. These are simply phenomenal. I do have a question, and perhaps some food for thought, on MSTP (802.1s).
The way load balancing is presented with this seems fine but, what if you already run a network with 3000+ VLANs and simply dividing them 1-1500 and 1501-3000 doesn't do the load balancing trick because traffic on VLAN 1-1500 is about 300% higher than on the second half of the VLANs. Since everything is already configured and running it seems like an impossible or perhaps unneeded approach to achieve layer 2 load balancing this way.
But is there a way to selectively assign what VLANs go into a ' batch' ? Cisco's Packet Tracer doesn't allow for MSTP usage it seems.
Thanks a lot for this great Learning Videos. I am finding little difficulties to identify what is Alternate and Backup Port. Any tips. I might hv to watch the video few more times. But if there is any obvious points I am missing Please guide. Thanks a lot.
Sir, you deserve more but I can't do more than a comment, like, share and subscribe!
I mean it...
Hi Jeremy, on Boson ExSim, is there a way to choose exam questions on specific topics? Or do I need to search for keywords in 'Question Review' and choose each question manually (i.e. like the one you did on PortFast at 40:30)? Also, thanks for another incredible lesson! STP my favorite topic thus far no doubt! Brilliant protocol!!!
You can filter by the 6 exam topic categories and/or keywords. I filter by keyword to find questions to use for these videos. (ie. 'spanning' for STP)
Jeremy, what abot learning state in RSTP+? Never mentioned it.
Hi Jeremy! In classic STP, I believe you said that BPDUs are only forwarded by designated ports. Therefore, can I correctly assume that in RSTP, where *all* switches originate BPDUs (not just the root bridge), this rule does not apply and BPDUs will be forwarded via other ports as well?
I don't think so, in RSTP they should be forwarded only out of designated ports too.
thx jeremy
Thanks :)
for a port to change from blocking to forwarding it would take 50s in classic (20s for max age, and 30s for forward delay timer) how long it takes for rapid stp? it did not cleary say it in the video
When determining the Root Port for a switch, do we consider the Root Cost of the switches individual outgoing interface? Or the Root Cost of the entire path to the Root Bridge that interface would take? Same with step 3 "interface on switch with lowest root cost"...do we consider the entire path to the Root Bridge or simply find the one interface on the switch that has the lowest Root Cost out of all interfaces connected to another switch?
Root cost is the root port's root cost. The root cost of other interfaces is only considered when deciding which will be the root port. In either case, its the total cumulative cost to the root, not the just cost value of that single interface (if that were the case, in almost all cases all interfaces on each switch would have the same cost).
jeremy, how a port is selected for the backup port--> what does it mean that the superior BPDU is recieved from the same switch, i mean we have to check for the bridge with lower bridge id and that bridge will be having the remaining port as the backup port , right?
'Superior' means 'better from the perspective of the STP process'. If the switch is the same, that means the bridge ID is the same. So, we're comparing the port priority and port ID.
Hello Jeremy! just want to clarify 39:06 how come Alternate port is in SW3 G0/1 and SW4 G0/1 and Backup port is in SW2 G0/2 Thankyou for your kind help!
SW3 G0/1 and SW4 G0/1 are alternate ports because they receive a superior BPDU from a different switch. SW2 G0/2 is a backup port because it receives a superior BPDU from a different interface on the same switch.
Thank you again for the course... how many labs are on the exam approx. and how many questions... thanks
No labs, and around 100 questions.
