Jeremy you are doing gods work my friend!! Thank you so much .

This one exercise test your subnetting, VLAN, Swithing, Routing and trunking. Love it. Thanks for doing all this work for us all. I will not miss a chance to to express how great your courses are. Absolutely recommended.

wow this is amazing, the confidence and abilities acquired from the practice, and the concise theory you provide is indescribable. Truly appreciate your work man

Thank you very much, these labs helps us understand the otherwise difficult theories. I am working on the server side, but these basic networking skills are invaluable in the daily trouble shooting process. Thanks millions.

thanks jeremy for your time to spend recording such videos for free .

Your lessons are amazing Jeremy! Thank you I have learned so much!

Thank you!

Thank you, helped a lot.

Thanks 😊.

Nice!

thank you

The connection between the two Switches you use Straight thru cables (I thought connecting same devices must user Cross-cable or the Switch is Auto-MDIX ready?) Thanks just asking I am a beginner CCNA Students studying Online :)

Hello, im pretty new in networking, and many things i dont unserstand. I know some pretty basic stuff like seitches routers, osi model, protocols etc. What course should i pass to be able to watch your videos and understand everything?

Hi, Sir Jeremy I hope you will answer my question sooner or later. Why you input the ip address 10.0.0.1 in 8:00 where this IP address came from?

can u please explain the native vlan concept regarding this activity?

why did u skip over the default gateway section so fast - that part was important

These labs were supposed to be just review, a way to practice things you already know, especially these early ones. Later on people said they wanted more explanation so I changed them a little bit.

Followed everything still couldn’t ping other vlans untill I did command vlan allowed all on all trunk ports.

Sweet

Hello, what this .13 means?

as you said in previous lab the switch you are using supports only one encapsulation. at step 1 vlan is not configured yet. that ,mean all pc's are on the same vlan, vlan 1 (native vlan). so, why is not pinging to all?

@JeremysITLab

It’s because the PCs are in different Layer 3 subnets: PC1 and PC3 in 10.0.0.0/25 and PC2 and PC4 in 10.0.0.128/25.

Hello Jeremy, thank you for a brilliant channel. I cannot seem to open the pkt lab files. Error: file cannot open on your version of packet tracer (7.1.1.0.138) I have a Dell laptop (new), though everything works fine on my Macbook pro. any comments?

why does ping fail in step 1?

Pros and Cons of adding the VLANs to the trunks between the two switches - By default I guess it is getting all of them - but is that a best practice?

@JeremysITLab

Best practice is to add just the necessary VLANs instead of allowing all of them. It does add extra work, though.

Hi, im new and i found your video is very easy to understand But can you explain the subnet part where pc 1 and pc 3 can ping each other, is it because of the ip you set? Why setting 10.0.0.130 is different from 10.0.0.1?

@redeemaralac1033

Жыл бұрын

they have different subnet mask, thats why this video is about inter vlan, you can route the different vlan and subnet mask...

@chunzhenwang9646

the main reason you dont understand this is because you dont know the difference between 10.0.0.1/24 and 10.0.0.1/25. you will figure it out once you understand.

Why do i have to trunk g0/1 on SW 1 and not trunk g0/1 on SW2 as well?

@magnificent_gaming

16 күн бұрын

From my understanding, on sw1 when we make that port a trunk the interface its connected to on sw2 is set to auto or dynamic desirable. Which automatically makes that interface on sw2 a trunk link.. Anyone can correct me if Im wrong. BUT I would like to know why we had to make a trunk link to the router myself. I think since we are creating dot1q we have to...

what configuration did you make to the original file such that, in the original setup, PC1 cannot ping PC2 or PC4 and PC2 cannot ping PC1 or PC3?

@JeremysITLab

They're all in different subnets, so they can't ping each other. They need a router to route the packets.

Hello Jeremy's I am following your labs. I am learning a lot of things. But currently, I have been stuck in this lab. On my end, both VLANs are not Pinging. I have made this topology 4 times and configured it but always the VLANs are not pinging. What is the solution? Please help

I can tell you, from personal experience, sometimes it's PT. you might want to restart PT. Also, try on GNS3 or Eve-Ng.

Hi Jeremy, when I was pinging 10.0.0.131 using pc1, I discovered that the packet sent 4,received 3 and lost 1=25% loss, pls what happened, I await your response

@JeremysITLab

4 жыл бұрын

That's because the first packet is sent before the ARP process completes. Try the ping again and you'll get 0% loss.

Remove the IP address from GigabitEthernet0/0/0 with the command 'no ip address', and then try assigning the subinterface address again.

Hii Jeremy, could you please help me too, when i try to add the second vlan, it says that it overlaps with g0/1.13 I also tried the NO IP ADDRESS but it doesnt work again. Thank you

is there any reason you wouldn't configure a sub int on the router for the native vlan? I was under the impression that you had to create a sub int for vlan 1 with the "encapsulation dot1q 1 native" sub interface command?

@JeremysITLab

Nope, no need to do so unless you'll be using the native VLAN.

Good , but you should explain gateway part,

@JeremysITLab

4 жыл бұрын

Hey Kele! Boson is far superior in my experience (I had both when I took my CCNA). Boson really tests your understanding of all of the topics, plus in depth explanations explaining why each correct answer is correct and each incorrect answer is incorrect, with references to Cisco documentation you can read online for further explanation. Alpha prep's questions were a little simpler, and had either short explanations, or in many cases no explanations. That was a couple years ago though, maybe they've stepped it up since then.
