Glad these lab instructions exists. I was SO close to getting it on my own and eneded up finding this out the hard way: no shut does NOT work on sub-interfaces! Besides my error, the instruction from the previous lesson really made things clear. Awesome work, Jeremy!
Couldn't solve this one on the first try, had to rewatch the previous video to realise that I didn't set the switch port that's connected to the router to a trunk port defiantly my favorite lab problem so far, I appreciate your work on this course, thank you!
For anyone confused, Mr Jeremy used an exemple in the comment section that helped me a lot. there it is : VLAN 20-tagged traffic will never pass between SW1 and SW2. For example, if PC5 pings PC1: PC5 sends the ping to SW2. SW2 sends to R1 (tagged in VLAN20). R1 routes the traffic and sends back to SW2 (tagged in VLAN10). SW2 sends to SW1 (tagged in VLAN10). SW1 sends to PC1. And then the return path is the reverse pattern. Hope it helps.
I am so thankful for these labs. I particularly like to go outside of the lab instructions and run commands I learned in the previous videos to keep them fresh. This lab in particular really had me stuck. I was pretty confident I had done everything correct but was unable to ping any PCs in vlan30 from PC7, PC6, and PC5. Spent a good bit of time making sure I configured everything. Went through all the steps I had done 3 times, looked at all the show outputs to see what I was missing and couldn't figure it out. Watched the video. Vlan30 wasn't on SW2 because I didn't even think about adding the vlan if there wasn't any PCs in vlan30 connected to the switch. Probably, won't forget to do that ever again after the headache I gave myself. Thanks again for making this course free and accessible!
I ran into that same problem, If switch 2 doesn't need to send any vlan20 traffic then why should switch 1 need to send vlan 30 traffic if there is no vlan 30 accessing it
@@ChristianRuales it's because sw2 does not know about vlan30 existence, you should add a simple {vlan30} command so sw2 will recognise it then it can sent traffic to the trunk port.. check 6:40
Same man, I made the same mistake and spent 20 mins troubleshooting haha, I managed to work it out myself though. Mistakes are such a useful and important part of learning!
Cant thank you enough for your videos! This comment is for anyone who was unable use PINGs to test interconnectivity. I totally forgot to configure G0/2 on SW2 and spent over an hour going over the configurations again. For me, i had to take a critical look at the traffic paths and check each interface along that path. Only then was i able to determine where the issue was.
4:52 To clarify. Frames sent from VLAN30 and VLAN10 destined to VLAN20 will have a 802.1Q TAG with their respective VLANS. EX: PC4(vlan30) > SW1>G0/1Trunk(vlan30 so it's allowed) > SW2 Then. SW2>G0/2Trunk(Vlan30 so it's allowed again) > RT1 From there the router will perform INTERVLANROUTING sending the traffic to VLAN20. In short, The 802.1Q tag identifies the source frame not the destination, hope it helps!

Hello Jeremy! Cannot thank you enough for these amazing videos. Fantastic job. I would like to ask why we allowed VLAN 30 connected to SW1 and not VLAN 20 connected on SW2 through the trunk? Is that part of the scenario and needed to do it like that exactly? Whatever the VLAN 30 is for SW2, VLAN 20 is exactly the same for SW1. I am sorry, I might missing something here but it would really help to to get this answer. Thanks a million
@@tferuh I came across with the same question but I figured it out… As VLAN20 is directly connected to it’s default gateway (R1) no need to configured in S2. Although VLAN30 needs to be connected to R1 to perform trunking it should be connected to SW2’s G0/1 interface. I hope this helps! All thanks to Jeremy!
Thank you so much Jeremy i increased the number of Switches and managed to make it work, after watching ur video and then successfully completing the task, I see trunking and switching a little bit easy, thanks bro👍🏽

Great video Jeremy. I did the lab by myself and encounter an issue with packet tracer. I did everything correctly and the pcs were not able to ping each other. after going through the configuration a few times I decided to close packet tracer and open it again just in case and that did the trick. just in case someone is having the same issue.
Slowly catching up and glad to see a little insight to netsim. I purchased the kit yesterday but have not delved into either one(exam or net) yet so this was good to watch.
Hi Ed, thanks for your support as always! Good move on getting ExSim and NetSim.

NetSim, however, is a great tool to use along with a book/video course! :)
@@JeremysITLab also glad to get your emails about the 25% off. That made buying the kit all the easier. I dabbled with both but I need to get caught up on the rest of your videos and start digging into the Boson software.
Thanks Jeremy for your time, this was well-explained. I will have to watch this video again in other to gain better understanding about the process of VLAN trunking.
Hi, i am so confused. Why do we allow VLAN 30 on SW2? We don't allow VLAN 20 on SW1 because there's no host in VLAN 20 connected to SW1, i get this but there's also no host in VLAN 30 connected to SW2 but we still allow it in the trunk. I'm lost here.
Bcoz SW2 is connected to R1 with a router on a stick so it is necessary to add a vlan trunk port which vlan is in use, and we don't allow vlan 20 is in SW1 because there is no host connected to SW1 Interface, if vlan 20 host wants ping the in SW1 they should have to go through Router (ROAS), bcoz SW1 do not have VLAN 20 Created. Thank you 😊
Because sw2 connected to router r1. R1 requires all vlan logical connection to do inter-vlan routing, so all vlan in the network has to be configured in this interface. CMIIW
Thanks alot Jeremy for the videos. Your videos are so easy to understand. Even who don't have much knowledge about ccna can get great knowledge from your videos .

Thanks Jeremy, great video. I failed to ping Vlan30 from PC1 at the first try, didn't know I need to and how to create Vlan 30 on SW2. Have to keep practicing otherwise it will be very easily to forget this detail.
The Boson netsim looks really helpful, thanks for showing it. I might have to try that after ccna when studying for ccnp encore (hopefully will have a job by then to be able to justify paying for it haha).
I could not get the PCs in VLAN 30 to connect with any others on the other subnets in this exercise, but I got the others properly configured. I'm learning a lot with these labs and lectures.
@@unimatelunimatel6175 I banged my head against a wall for 30min on this lab. I usually do the labs and don't watch the lab video unless I need help. I could not figure out what I was doing wrong. Went back and watched the video and still missed it. Then I decided to close the packet tracer lab and start from scratch and rewatch the video and then I saw it and it clicked. I was missing vlan 30 in Sw2 the whole time. Facepalm!
Hey @JeremysITLab I followed exactly every step in the video because PC5 wouldn't successfully receive or send pings to the other PCs. I figured out that you do have to 6:09 allow VLAN 20 on SW2 in order for it to ping (maybe you have to configure it for it to reach the router? or it's a packet tracer glitch) . I know you explained that you wouldn't have to but like I said even when I followed step by step it wasn't working. I don't know how nobody else caught this but I wanted to point it out as my thanks for your videos!
@@JeremysITLab it did work when redoing it your way but I swear i added the vlan30. It is probably because I didn't allow trunk vlan 10,20,30 for SW2 interface G0/2 since I don't recall that. Thanks again!
Hello! First of all I want to thank you for this course! it's extraordinary! I've done this lab 3 times and I can't get past a simple problem. PCs do not communicate with PCs in a different VLAN. communicates only with PCs from the same vlan .. where is the problem? trunk ports seem ok on both sw's
Hi Jeremy, Thank you so much for one of the best and amazing CCNA course, clear introductions, instructions and very useful labs!!!! I followed your recommendation about Boson, and would like to share my experience. Two days ago I purchased Boson NetSim, and must say my first impression is ...very disappointed... Boson should improve many things, instructions are not clear, very confused, detailed topology (interfaces, ports numbers) are part of the introduction only, not as separate topology, PC configuration is in CMD, some of the labs are already configured and that is not introduced on the beginning of the lab instructions... Lab designer is very poor, Packet tracer, GNS3, VIRL are far better than this one. Honestly, would not recommend Boson NetSim for lab practicing, I think they should learn from you how to design the labs... All the best and keep up the good work!!! S.
A packet tracer glitch caused me to spend way more time on this lab than I needed, but at least going through the configurations a ton of times made me more comfortable with setting up vlans.
Hi Jeremy's. thanks for gives this opportunity to get familiarized with Cisco products. On SW1you didn't add the VLAN 20 (G0/1) because you said that there is no VLAN 20 interfaces connected to SW1, however you add VLAN 30 to SW2 (G0/0) when there is no VLAN 30 interfaces connected to SW2. Could clarify. Thanks.
wow Jeremy,Thanks i was doing the lab by myself and it didn't ping other networks beside VLAN 10 and no matter what i did it didn't add the VLAN to the Managment domain(when you do- "sh int trunk". anyway i just needed to add the vlan via a cmd- "int g0/1>>>VLAN 30" same thing on SW2 only diffrent vlan i can't belive that i missed that tiny detail! anyway thanks again~!
Thank you Jeremy for another amazing video. I did the practical via packet tracker using the last lecture video and I got it. Could share the pkt file for review if you wouldn't mind.
Here is new link if you're having difficulties with access to the previous link. drive.google.com/file/d/1YAIlUQ9Wd22g7AqeU9hOjkkI1fi-9jsH/view?usp=drivesdk
Why is VLAN 20 not allowed on SW2? I re-watched the day 17 lecture but couldn't find the answer. SW2 could send VLAN 20 traffic on the trunk if a host in VLAN 20 pings a host in VLAN 10 or 30
i had the same question i was confused as well, i guess the answer is becuz when it's sent to others, there's the vlan tag, and the vlan 20 tag wont be required? im not sure either. sorry
if you are talking about 6:20, it's beacause he's talking about interface G0/1 of the switch, not the entire switch. vlan 20 will never send any trafic over that trunk port, since there are no vlan 20 hosts connected to switch 1.
Vlan 20 can go straight to router, but vlan 30 and 10 need trunk to get to router. Makes it a bit confusing as there is also another vlan 10. This easiest way to understand it.
@@lumen_synths It is allowed on SW2, but only in interface g0/2. It's not allowed on interface g0/1 because there is no need. All vlan 20 traffic will travel to the router and the switch will change the vlan of the packet to the destinations vlan.
Hi, first of all, thank you so much for your valuable video. For two days I was trying to do the same lab but I wasn't a success there in the video you didn't show pc configuration in the packet tracer. tried to communicate with different VLAN so there needs to put default gateway IP. thanks once again for your video and I'm following your course.
@@JeremysITLab Thank you so much for your concern and suggestion, I didn't download the lab. I tried to do that also but I couldn't find the file. when clicking on the link it redirects to me natcad site.
Hi Jeremy, thank you so much for this course i find it so much easier to follow this then read the books on this material. i have signed up to your email list has there is no link to the lab in the description. i hope you can send this through to me as i am trying to get through as much videos as i can during the lock down. thank you again.
I had problems with the vlan 30 on SW2 until I didn't create this vlan there. Were it not for this video, I wouldn't be able to come up with the solution, thanks!
I have a question. We just set trunk allow VLAN10 and VLAN30 between sw1 and sw2. Why pc5 in vlan 20 can ping pc3 in vlan 30？ Any help will be appreciated。 thank you
Thank you very much Jimmy for this lab please can you tell us how we can configure the native vlan in the g 0/0 on the router and in the sub interfaces. Thank you
Hi Jeremy, thanks again for providing the link to the pre-made labs, it definitely helped a lot. Question, why does the ping from VLAN 10's PC7 to VLAN 30's PC3 have to go through the router if there is a trunk established for VLANs 10 & 30? Is it because they aren't in the same VLAN? Just want to make sure so I understand. Thank you!
The switch won't forward data from a PC in VLAN 10 to a PC in VLAN 30. The trunk means that traffic in both VLANs can be forwarded over that specific link, but that doesn't mean the switch will send the VLAN 10 traffic to the VLAN 30 PC.
HI @Jeremy. When I try to ping from PC6 (VLAN10) to PC4 (VLAN30) ping does not work. Upon checking in simulation mode, I noticed the ARP reply is coming form R1 to SW2 is getting blocked in SW2 with the message "1. GigabitEthernet0/2 is blocked by STP. The device drops the frame." However ping to any PC in VLAN10 to VLAN10 works. Please advise.
Hi! My guess is that you haven't allowed VLAN 30 on the SW1-SW2 trunk, or you haven't created VLAN 30 on SW2. *Add VLAN 30 to the trunk:* SW2(config)# interface g0/1 SW2(config-if)# switchport trunk allowed vlan add 30 *Create VLAN 30* SW2(config)# vlan 30 SW2(config-vlan)# exit
Hello Jerebear and friends, I was at 9:39, configuring subinterfaces on the router and I named the subinterfaces like this: g0/0.1, 0.20, 0.30. As a result, I wasn't able to ping. Is there a reason for this? Maybe I misconfigured something else because naming the subinterfaces like this shouldn't matter, right??
Hello, I am close to wrapping up this excellent video series. I do plan on downloading the Boson Netsim and practicing commands and lab configurations. Is there anything else you recommend to study before taking the exam? Any books or practice exams?
Yes you will definitely need a set of books (I recommend Cisco's official guides by Wendell Odom) or another video course, my video course isn't finished yet so there are MANY topics that I haven't covered yet.
Hi @JeremysITLab in packet tracer lab why didn't you create the native VLAN in the router (creating a subinterface or adding IP address to the interface g0/0)?
I am a little confused at why we had to add vlan 30 to the allowed and active in management domain on sw2 and no just add it to the allowed on trunk? Also, if we have to add 30 to the allowed and active in management in domain on sw2, why not add 20 on sw1?
Broski.. the two different switches have their respective v-lans.. SW1 has Vlan 10 and Vlan 30. Just those two Vlans were created on that Switch..... VLAN 20 has no business sending traffic over there. Vlan 20 will send its traffic to the Router via Switch 2, Remember, Vlan 20 and Vlan 10 were created on Switch 2. Switch 1 needs to get to the ROUTER, so since SW 2 is the way to get there, Switch 2 needs to match Switch 1 inter Vlan . Remember, the ROUTER is the KEY. Since SW2 never heard of VLAN 30 being that VLan 20 and Vlan 10 were created on it via access ports, it needs to have a VLan 30 created. I hope this helps.. this is my attempt of helping myself learn this, Lord knows I bumped my head on this for some hours, but now it makes sense..God bless
Hi Jeremy, I am not sure if you will reply to this comment but I really hope you do. First of all, thank you for sharing this course on RUclips for free. You are a life saver. Secondly, I am having trouble accessing the packet tracer labs. I can access the labs on your google drive but they are not similar to the ones you are using or not clearly labeled. Could you kindly assist me. Thanks.
Hello Jeremy, when i try to open the .pkt i have an error about the version of packet tracer, that never happen before with ur lab :( can u check that please ? thanks in advance
Hi Jeremy, first of all thank you for these in depth & amazing lectures. I have learned CCNA before but with your course i am always learning something new with every lecture. I have a question, you created an empty VLAN 30 on SW2, but isn't it important to create a similar empty VLAN 20 on SW1 ?? Why so?
SW2 needs VLAN30 because VLAN30 traffic will be sent to R1 via SW2 for inter-VLAN routing. However, no VLAN20 traffic will ever be sent to SW1. There are no end hosts in VLAN20 connected to SW1, and the router isn't connected to SW1 either, so it's unnecessary.
Awesome work you are a really good teacher, I have one question about one part (at 17:30 in video) the way to discover which port each pc is connected to ! . In packet tracer I try the show Mac address table but there no listing about example PC1, if I create some traffic it will appear. But my question is, how to find this information if example your try to discover in real situation if the information of Mac address doesn't list those Mac address, there another way to find it ? or another command ? thank in advance
Glad these lab instructions exists. I was SO close to getting it on my own and eneded up finding this out the hard way: no shut does NOT work on sub-interfaces!

@@unimatelunimatel6175 I banged my head against a wall for 30min on this lab. I usually do the labs and don't watch the lab video unless I need help. I could not figure out what I was doing wrong. Went back and watched the video and still missed it. Then I decided to close the packet tracer lab and start from scratch and rewatch the video and then I saw it and it clicked. I was missing vlan 30 in Sw2 the whole time. Facepalm!
@@oscarm534 I did the exact same thing and when I saw your comment I knew immediately. Thanks!
I Love you Jeremey ❤ I can’t thank you enough for what you do.!
These courses are very helpful!
I love them.
Thanks Jeremy.
Day 17 Lab was awesome! Thank you Jeremy!
Sir, you deserve more but I can't do more than a comment, share and subscribe!
I mean it.
You the man, Jeremy!
Thank you! YOU the man!
Hey @JeremysITLab I followed exactly every step in the video because PC5 wouldn't successfully receive or send pings to the other PCs. I figured out that you do have to 6:09 allow VLAN 20 on SW2 in order for it to ping (maybe you have to configure it for it to reach the router? or it's a packet tracer glitch) . I know you explained that you wouldn't have to but like I said even when I followed step by step it wasn't working. I don't know how nobody else caught this but I wanted to point it out as my thanks for your videos!
Just tested it myself, and you don't need to allow VLAN 20 on the trunk. My guess is you forgot to manually create VLAN 30 on SW2.
@@JeremysITLab it did work when redoing it your way but I swear i added the vlan30. It is probably because I didn't allow trunk vlan 10,20,30 for SW2 interface G0/2 since I don't recall that. Thanks again!
18:30 Yes sir you did mention that about the CLI command : #show mac address-table
Thanks! Good memory!
Hello! First of all I want to thank you for this course! it's extraordinary!
I've done this lab 3 times and I can't get past a simple problem. PCs do not communicate with PCs in a different VLAN. communicates only with PCs from the same vlan ..
where is the problem?
trunk ports seem ok on both sw's
It seems there's a problem with routing. Check the configurations for the connection between R1 and SW2.
Jeremy, you are a Great teacher.
Thank you Raivel!
Hi Jeremy,
Thank you so much for one of the best and amazing CCNA course, clear introductions, instructions and very useful labs!!!!
I followed your recommendation about Boson, and would like to share my experience. Two days ago I purchased Boson NetSim, and must say my first impression is ...very disappointed... Boson should improve many things, instructions are not clear, very confused, detailed topology (interfaces, ports numbers) are part of the introduction only, not as separate topology, PC configuration is in CMD, some of the labs are already configured and that is not introduced on the beginning of the lab instructions... Lab designer is very poor, Packet tracer, GNS3, VIRL are far better than this one. Honestly, would not recommend Boson NetSim for lab practicing, I think they should learn from you how to design the labs...
All the best and keep up the good work!!!
S.
Sorry to hear you didn't like it, I think it's great!
A packet tracer glitch caused me to spend way more time on this lab than I needed, but at least going through the configurations a ton of times made me more comfortable with setting up vlans.
thank you so much :D i did the lab with out watching this video
Good job! :)
Hi Jeremy's. thanks for gives this opportunity to get familiarized with Cisco products.
On SW1you didn't add the VLAN 20 (G0/1) because you said that there is no VLAN 20 interfaces connected to SW1, however you add VLAN 30 to SW2 (G0/0) when there is no VLAN 30 interfaces connected to SW2.
Could clarify.
Thanks.
wow Jeremy,Thanks i was doing the lab by myself and it didn't ping other networks beside VLAN 10
and no matter what i did it didn't add the VLAN to the Managment domain(when you do- "sh int trunk".
anyway i just needed to add the vlan via a cmd-
"int g0/1>>>VLAN 30"
same thing on SW2 only diffrent vlan
i can't belive that i missed that tiny detail!
anyway thanks again~!
Thanks a lot sir!!!! these lab exercises really help to clarify such complex topics.
Thank you! Glad to hear that :)
I am still going through nicely, Thank You jeremy
hardest lab so far by a mile!
Confusion is on vlan 20 not configured as trunk
very good, this really helps to build up hand on experience

Why is VLAN 20 not allowed on SW2? I re-watched the day 17 lecture but couldn't find the answer. SW2 could send VLAN 20 traffic on the trunk if a host in VLAN 20 pings a host in VLAN 10 or 30
i had the same question i was confused as well, i guess the answer is becuz when it's sent to others, there's the vlan tag, and the vlan 20 tag wont be required? im not sure either. sorry
Still trying to figure this out...
if you are talking about 6:20, it's beacause he's talking about interface G0/1 of the switch, not the entire switch. vlan 20 will never send any trafic over that trunk port, since there are no vlan 20 hosts connected to switch 1.
Vlan 20 can go straight to router, but vlan 30 and 10 need trunk to get to router. Makes it a bit confusing as there is also another vlan 10. This easiest way to understand it.
@@lumen_synths It is allowed on SW2, but only in interface g0/2. It's not allowed on interface g0/1 because there is no need. All vlan 20 traffic will travel to the router and the switch will change the vlan of the packet to the destinations vlan.
Wow this is nice, thank you Jeremy, you are very good at doing it.
Thank you!
Super helpful lab. Thank you!
Hi, first of all, thank you so much for your valuable video. For two days I was trying to do the same lab but I wasn't a success there in the video you didn't show pc configuration in the packet tracer. tried to communicate with different VLAN so there needs to put default gateway IP. thanks once again for your video and I'm following your course.
Yep, never forget the default gateways! By the way, did you download my lab files? The default gateways should be pre-configured in my lab files.
@@JeremysITLab Thank you so much for your concern and suggestion, I didn't download the lab. I tried to do that also but I couldn't find the file. when clicking on the link it redirects to me natcad site.

We configure vlan 30 on switch two?! Why? Is it the same thing as doing it on switch one?
Thanks a lot, Jeremy
Thanks for watching and leaving a comment :)
I had problems with the vlan 30 on SW2 until I didn't create this vlan there. Were it not for this video, I wouldn't be able to come up with the solution, thanks!
Glad to help :)

I like all your free ccna 🎉🎉🎉
good job jeremy!!
thanks for video. great videos
Hi jermy.can you make a video based on ccna.How ccna projects works on IT field.
Right now I'm busy with my CCNA course, I might make other videos later.
Good lesson
Thank you very much Jimmy for this lab please can you tell us how we can configure the native vlan in the g 0/0 on the router and in the sub interfaces. Thank you
I cover it in day 18! Check the next video ;)
@@JeremysITLab ok thank you for the reply
Thank you Jeremy.
Hi Jeremy, thanks again for providing the link to the pre-made labs, it definitely helped a lot.
Question, why does the ping from VLAN 10's PC7 to VLAN 30's PC3 have to go through the router if there is a trunk established for VLANs 10 & 30? Is it because they aren't in the same VLAN? Just want to make sure so I understand.
Thank you!
The switch won't forward data from a PC in VLAN 10 to a PC in VLAN 30. The trunk means that traffic in both VLANs can be forwarded over that specific link, but that doesn't mean the switch will send the VLAN 10 traffic to the VLAN 30 PC.
Thank you Jeremy
Nice explanation. :-)
Thank you! :)
Thanks, excellent video.
Thank you :)
thank you so much
Thanks for watching :)
HI @Jeremy. When I try to ping from PC6 (VLAN10) to PC4 (VLAN30) ping does not work. Upon checking in simulation mode, I noticed the ARP reply is coming form R1 to SW2 is getting blocked in SW2 with the message "1. GigabitEthernet0/2 is blocked by STP. The device drops the frame." However ping to any PC in VLAN10 to VLAN10 works. Please advise.
Hi! My guess is that you haven't allowed VLAN 30 on the SW1-SW2 trunk, or you haven't created VLAN 30 on SW2.
*Add VLAN 30 to the trunk:*
SW2(config)# interface g0/1
SW2(config-if)# switchport trunk allowed vlan add 30
*Create VLAN 30*
SW2(config)# vlan 30
SW2(config-vlan)# exit
Had the same issue, thank you
Hello Jerebear and friends,
I was at 9:39, configuring subinterfaces on the router and I named the subinterfaces like this: g0/0.1, 0.20, 0.30. As a result, I wasn't able to ping. Is there a reason for this? Maybe I misconfigured something else because naming the subinterfaces like this shouldn't matter, right??
Hello Jeremy thanks alot for all you do.Please how do I finish the lab in this video,can't find the link in your Bio section.Please can anyone help
Amazing contents ,thanks
Hello, I am close to wrapping up this excellent video series. I do plan on downloading the Boson Netsim and practicing commands and lab configurations. Is there anything else you recommend to study before taking the exam? Any books or practice exams?
Yes you will definitely need a set of books (I recommend Cisco's official guides by Wendell Odom) or another video course, my video course isn't finished yet so there are MANY topics that I haven't covered yet.
Fascinating!
Hi @JeremysITLab in packet tracer lab why didn't you create the native VLAN in the router (creating a subinterface or adding IP address to the interface g0/0)?
I didnt add VLAN 30 to SW2 G0/1 interface and kept getting DTP and CDP. DUH! lol Thanks! All the other pcs were able to ping.
Thank you a lot !
Thanks for your support, Jaro!
12:03 you say we will ping PC3 in VLAN 20, I think you meant VLAN 30 :)
I am a little confused at why we had to add vlan 30 to the allowed and active in management domain on sw2 and no just add it to the allowed on trunk? Also, if we have to add 30 to the allowed and active in management in domain on sw2, why not add 20 on sw1?
Broski.. the two different switches have their respective v-lans.. SW1 has Vlan 10 and Vlan 30. Just those two Vlans were created on that Switch..... VLAN 20 has no business sending traffic over there. Vlan 20 will send its traffic to the Router via Switch 2, Remember, Vlan 20 and Vlan 10 were created on Switch 2. Switch 1 needs to get to the ROUTER, so since SW 2 is the way to get there, Switch 2 needs to match Switch 1 inter Vlan . Remember, the ROUTER is the KEY. Since SW2 never heard of VLAN 30 being that VLan 20 and Vlan 10 were created on it via access ports, it needs to have a VLan 30 created. I hope this helps.. this is my attempt of helping myself learn this, Lord knows I bumped my head on this for some hours, but now it makes sense..God bless
Hi Jeremy, I am not sure if you will reply to this comment but I really hope you do. First of all, thank you for sharing this course on RUclips for free. You are a life saver. Secondly, I am having trouble accessing the packet tracer labs. I can access the labs on your google drive but they are not similar to the ones you are using or not clearly labeled. Could you kindly assist me. Thanks.
Hello Jeremy, when i try to open the .pkt i have an error about the version of packet tracer, that never happen before with ur lab :( can u check that please ? thanks in advance
Same here
Hi Jeremy, first of all thank you for these in depth & amazing lectures. I have learned CCNA before but with your course i am always learning something new with every lecture.
I have a question, you created an empty VLAN 30 on SW2, but isn't it important to create a similar empty VLAN 20 on SW1 ?? Why so?
SW2 needs VLAN30 because VLAN30 traffic will be sent to R1 via SW2 for inter-VLAN routing. However, no VLAN20 traffic will ever be sent to SW1. There are no end hosts in VLAN20 connected to SW1, and the router isn't connected to SW1 either, so it's unnecessary.
@@JeremysITLab Thank you very much Jeremy, i got it now. Had a little confusion. All clear now.
@@JeremysITLab Great explanation Jeremy! this answered my question as well. Splendid...
@@JeremysITLab Thanks Jeremy, was confused by this also.
@@JeremysITLab Then why wouldn't we add VLAN20 to SW1 in case a device on SW1 wants to talk to a device on VLAN20 (SW2)? I'm confused on this.
I finally solved why I was getting errors and was unable to ping....I fixed it.
Awesome work you are a really good teacher, I have one question about one part (at 17:30 in video) the way to discover which port each pc is connected to ! . In packet tracer I try the show Mac address table but there no listing about example PC1, if I create some traffic it will appear.
But my question is, how to find this information if example your try to discover in real situation if the information of Mac address doesn't list those Mac address, there another way to find it ? or another command ? thank in advance
