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
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!
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!
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 !!!
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.
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.
I'm so satisfied that I answered flawlessly to the quiz! I begin to fully understand the STP and RSTP/Rapid PVST. I still have struggle with some details, but I keep going! Thanks for your videos, Jeremy!
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.
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. 😄
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!
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!!!!
Another excellent video. Thank you. I especially benefited from quiz question 4 and your subsequent detailed explanation. I appreciate the work you put into these questions.
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?
Wow, me getting the RSTP Quiz 4 question right was satisfying. Adding hubs into the mix really trips me up, but I am proud I got it right :) And it's all thanks to you, Jeremy. Thank you so much.
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, 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.
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.
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 RUclips. You're still awesome. Your friend you've never met, Timmy Tim McTimson
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,
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
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.
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
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
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.
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
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?
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.
@@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
@@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,.
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.
Hi, thank you all for the work that has been done for the CCNA . I have a small question regarding the Question 4 RSTP quizz : Why SW3 took G0/2 as a root port even though it has G0/1 which has lower port ID ? (Since the cost is the same) Same with SW4 : Why does he take g0/0 as root port even though the cost doesn't add and SW2 has lower mac The other for me stp is : - Root bridge (prio then MAC) - Port role (Cost then Brigde ID (Prio then MAC) - PID What do I do wrong if someone can explain me, I would be very grateful
Hi! I'll give some quick answers to your questions: 1) SW3 selected G0/2 because it is connected to a lower port ID on SW1. Remember, it's the neighbor port ID, not the port ID on this device, that is important. SW3 G0/1 is connected to SW1 G0/2. SW3 G0/2 is connected to SW1 G0/1 (lower port ID) 2) SW4 selected G0/0 as its root port because it has the same root cost via SW2 and SW3, but SW3 has a lower bridge ID (lower priority: 8193 vs 32769).
Ahhh okay thanks a lot, I was doing the local PID not the neighbour PID thanks a lot that helped a lot. Planning to get the exam around December still some work to do
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.
Hi Jeremy. Found a slide typo at around the 16 minute mark on the video: “BackboneFast allows SW3 to expire the *made* age timers...” instead of ...”expire the *max* age timers...”
When will Cisco create Super Mega Meta PVST++ in response to the IEEE? lol. Ignore the following, they've all been addressed in an "errata" comment already: Also, a trivial mistake at 16:01: "made age timers" vs. "max age timers". Yet another: SW1 has two G0/0 interfaces at 38:50. I'm probably the one in the wrong on this last one, but don't SW3's /1 & /2 interfaces have their roles swapped in the same quiz question's answer? The lower port ID receives the root port role, correct?
I wonder why Cisco decided to make the CCNA one exam, there is so much ground to cover and I believe the old two exam format is better for potential CCNA designates. Anyway, thank you Jeremy for the detailed content.
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)
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?
I have a question if someone can explain in quiz 4 How does the SW2 uses the root cost to selects it's G0/1 interface as designated. I thought it chose it because of the lower bridge 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.
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.
I have carrer question , after learning Networking what should I learn next for Network admin Job or similar kind ? ... I have working experience on K8's , Docker , Linux , shell scripting, AWS , Open shift and Open stack By the way love the videos ... Thank You ...
Hi Jeremy, Thanks for your Awesome CCNA videos. Do you have videos on BGP. Please share the Link or name of the videos. Searched for them, but didn't get.
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

Hi, thank you all for the work that has been done for the CCNA .
I have a small question regarding the
Question 4 RSTP quizz :
Why SW3 took G0/2 as a root port even though it has G0/1 which has lower port ID ? (Since the cost is the same)
Same with SW4 : Why does he take g0/0 as root port even though the cost doesn't add and SW2 has lower mac
The other for me stp is :
- Root bridge (prio then MAC)
- Port role
(Cost then Brigde ID (Prio then MAC)
- PID
What do I do wrong if someone can explain me, I would be very grateful
Hi! I'll give some quick answers to your questions:
1) SW3 selected G0/2 because it is connected to a lower port ID on SW1. Remember, it's the neighbor port ID, not the port ID on this device, that is important.
SW3 G0/1 is connected to SW1 G0/2.
SW3 G0/2 is connected to SW1 G0/1 (lower port ID)
2) SW4 selected G0/0 as its root port because it has the same root cost via SW2 and SW3, but SW3 has a lower bridge ID (lower priority: 8193 vs 32769).
Ahhh okay thanks a lot, I was doing the local PID not the neighbour PID thanks a lot that helped a lot.

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.
37:54 SW2 appears to have a lower bridge ID of 2.2.2 rather than SW3's 3.3.3
Keep in mind the bridge ID consists of two parts: priority and MAC address
just amazing 👍
Sir, you deserve more but I can't do more than a comment, like, share and subscribe!
I mean it...
all clear thank you sir
Hi Jeremy. Found a slide typo at around the 16 minute mark on the video: “BackboneFast allows SW3 to expire the *made* age timers...” instead of ...”expire the *max* age timers...”
Thanks for pointing that out!
THANK YOU SO MUCH JEREMY
Thank you Sadun!
When will Cisco create Super Mega Meta PVST++ in response to the IEEE? lol.
Ignore the following, they've all been addressed in an "errata" comment already:
Also, a trivial mistake at 16:01: "made age timers" vs. "max age timers".
Yet another: SW1 has two G0/0 interfaces at 38:50.
I'm probably the one in the wrong on this last one, but don't SW3's /1 & /2 interfaces have their roles swapped in the same quiz question's answer? The lower port ID receives the root port role, correct?
I wonder why Cisco decided to make the CCNA one exam, there is so much ground to cover and I believe the old two exam format is better for potential CCNA designates. Anyway, thank you Jeremy for the detailed content.
Yeah the two exam option was great! Especially for those new to the field, the scope of the CCNA can be a bit overwhelming.
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)
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?
Yes
It's an honor, Mr. President.
I have a question if someone can explain in quiz 4
How does the SW2 uses the root cost to selects it's G0/1 interface as designated.
I thought it chose it because of the lower bridge 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.
Videos well expressed
ERRATA: At 11:37 the first column name will be 'Rapid STP Port State' not STP Port State.
Thanks for your great help Jeremy 😊 🇧🇩
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.
I have carrer question , after learning Networking what should I learn next for Network admin Job or similar kind ? ... I have working experience on K8's , Docker , Linux , shell scripting, AWS , Open shift and Open stack
By the way love the videos ... Thank You ...
Hi Jeremy, Thanks for your Awesome CCNA videos. Do you have videos on BGP. Please share the Link or name of the videos. Searched for them, but didn't get.
still following along to see if the Channel Failed to Load ever gets fixed.
thank you very much for that effort
Thanks mr Jeremy
