Hey Keith, thanks for this, really enjoyed. DO you have a video that goes through the process of building this PT lab from start to finish? If not, I think it would be amazing video as it touches on so many topics. thanks again.
I always watch your videos whenever I am confused how networking stuff works. Do you have video tutorials on how you do the configurations on this 3 tier topology? Thanks
Thanks Keith. I was thinking during the video if asking for a video of how you did the lab was a bit too cheeky but then you said you have put it out for us anyway so saved me having to ask. Much appreciated as always 🙌
4:24 you say there is a highspeed connection between the two buildings. Why (for the video I know) you are drawing some more devices? That we don't need if the distribution layer switches are connected to each other?
This video is very helpful! Do you have any that are a little more beginner friendly when it comes to network design? Thanks! I’m a cybersecurity major and I am very interested in network design but still learning some of the basics, thanks.
I can't find the lab on your website, has it been removed or renamed? I'd like to check it out because I've actually got a question about STP between the Access and Distribution Layer switches: all lights are green between all ports, so STP doesn't seem to block anything. Has STP not been configured on them (eg 10:32)? Have a nice day.
Thank you @progressivehouseclusive3835! An unmanaged switch (one that can't be configured) is 1 large L2 broadcast domain (VLAN). On a managed switch, it allows for the configuration of multiple L2 broadcast domains (VLANs). www.youtube.com/@KeithBarker/search?query=VLANs
I couldn't do this on my own. I have downloaded the pkt file. Still I couldn't figure it. I have configured OSPF but it doesn't show when I command show ip route. It shows the three connected VLANs only.
I have a question, if I'm using an IPsec VPN to connect two sites, then PAT would not be necessary right? If not, then how to configure PAT in a way such that it doesn't interupt the tunnel
Thank you for the question @Shake_Well_Before_Use. Between two sites that already have unique IP subnets, NAT/PAT would NOT be required on the tunneled traffic. It could be done, but wouldn't be required in that situation. In short, yes, you are correct.
Hello mr keith barker , thanks for your lessons I always watch your videos series especially CCNA related topics . But I want to ask you , many CCNA teachers or CCNA professionals saying it’s good for CCNA student to have the NETSIM-BOSON OR EXSIM , so My question is which of these two softwares is best for CCNA student or both are good for him. I need your advice, many thanks
hey Keith, could you please share the link to the board you using for presentation? which version of the cisco packet tracer are you using cause I did download the 2 tier topology that was not compatible with what version I have, mine is version 8.
Thanks a lot Keith. I only have one question I can't seem to understand.. How does the server associate the dhcp pool to the right pc requesting the address ? There is no trunking between the router (connected to the server) and the core switches (they transfer the 777 vlan only anyway), and the 3 layer distribution switch which has the same "ip helper" address associating to the server does not pass on the vlan by which the user is on and is requesting the address. In simple words : how come a user on vlan 20 doesn't get (by mistake) a layer 3 address associated with vlan 30 (for instance) ? The server itself (as far as I understand) has no way of knowing from which VLAN the request was made since its receiving info on an access port and its not a layer 2 intermediate device anyway.. Does the "Vlan Pool" name on the server has any significance in this matter?
Have you received an answer for your question yet? The way it get's the correct IP from the correct dhcp pool is by the VLAN assigned to the switch port the device is connected to.
Can you explain to me how you're making the text appear/fill-in quickly as you speak? Are you pasting it in there or are you pausing the video for a split second? LOL.. OR Are you speaking over a previously-recorded video that has been slightly sped-up? Thanks.
Thank you for the question @doggystyledave. I don't do voice overs, but I use some editing tools to remove sections that have no audio. That would account for text and commands showing up faster.
@@KeithBarker I appreciate your videos!! One of the best things about watching them is that you don't just READ a script at 1000 MPH- I don't understand how others think we can learn like that! I have had to slow others" videos down to 0.75 speed (using UA-cam Options) to watch them.
The 2-Tier is what a home network is. In the 3 Tier topology it is more splitted in different sections. Actually simple😊
I've completed my CCNA and this still taught me how to put my CCNA skills together into a network rather than practicing each skill individually
Thank you @TurkMovement!
Keith as always this is great, thank you for the content you put out, really helps with my CCNA studies 👍
Happy to help!
Please when doing labs, make a video of you doing it, That would make a good video lesson.
You are very good at networking I hope I can understand all of this like you it’s impressive how many years have you been learning this?
Happy new year Mr Keith, may the almighty bless you and keep safe. I really enjoy the videos a lot.
Same to you!
Thanks Keith for breaking this concept down.
Happy to do it, thanks for the feedback zoltron30.
This lesson as well as the pkt.file you included is absolute GOLD!! thank you Keith 🤞🏿
Amazing explanation! Studying for my net+ and came across this.
Thank you yucrysoez! Happy studies, and good luck on your Net+
@@KeithBarker appreciate it, I passed 🙂
Dang, you’re good at this…. Thanks!

Thank you @sarahchua2811!
I don't think I have a full video on the configuration of the 3 tier. Sorry.
Getting back in the game!
Thank you so much for making this video, and many other videos, we do appreciate your kindness sir 👍
My pleasure
Thank You Keith!!!! Awesome Lab and tutorial!!!
Happy to do it, thanks for the feedback Sam Jones.
Excellent
Thank you! Cheers!
Love your studio looks well cool!
Thanks so much!

EXCELLENT VIDEO!!!!
Thank you!
core switches and distribution switches are not connected via trunk but through access interfaces, why?
This video is very helpful! Do you have any that are a little more beginner friendly when it comes to network design? Thanks! I’m a cybersecurity major and I am very interested in network design but still learning some of the basics, thanks.
keith you are an amazing guy. Your videos are so clear with tons of great info. Keep going i love it
I appreciate that!
AMAZING 👏

I didn't know layer 2 switches can support VLANs.

This is good.
happy new year Mr Barker , just one wish ask u to help us it just to set up atest for reviewing all the CCNA plz ii m from algeria
Hi Keith, happy new year. Please, something wrong happens with the captions of this video
How can a layer 2 core switch do interVLAN routing? Am I missing something here? Keith said 'Layer 2 core' right?
Thank you for the question LE.
The distribution blocks are connected to each other, over the layer 2 core. Each of the blocks can route to each other.
Keith how would this integrate with a spine and leaf data centre topology?

What application you use in infographic
Thank you for the question @NilvinPerpinosas. When I am drawing, I am using Epic Pen.

Thank you for the question MY TIME. Boson makes quality and useful products, including their labs and questions.

Had the same issue - download and install newest version 8.1.0 - should work then

Dude, what is that awesome looking blackboard/notation software?
Thank you for the question EyeInTheSky.
It is just a .jpg of a blackboard, and I use epic-pen with a wacom tablet to draw.
Best wishes!
