Hello Keith, thank for providing this content. I passed my CCNA thanks to your networking videos and contagious enthusiasm.
Congratulations Mel R❗
So great to hear, way to get it done. Best wishes on your continued success.
Your energy is amazing Keith, you make learning fun. If every teacher had your energy we would all be in a better place. Thank you for the content !!
Happy to do it, thanks for the feedback Junior Gonzalez.
Glad to see that these concepts are still relevant since I got my CCNA in 2016. Thank you for this refresher.
Happy to do it, thanks for the feedback SoulJah876.
@@KeithBarker And thank you for helping me secure that and other certs over the years. You deserve a ton of awards. Be blessed.
Sir Keith since your CBTz I am your fan amazing skills and teacher you are 👌👌👌
Thank you Keith for the time you put on your videos! It's easier to watch networking videos again. My question is why the switch from PT to EVE-NG? And what happened to GNS3? You have been very motivational for me to get my CCNA, so I'm refreshing with your videos.
Thanks again Keith. I'm still just using Packet tracer but I guess its time to get into GNS3 too.
Hello Keith, Your Video was very informative.
I am using M1 Mac.
EVE-NG is not available, but I learned a lot.
Thank you very much.
Great to hear!
Hello Keith
Great content as always.Just on the Router on a stick example wouldn't be more secure to use the switchport trunk allowed vlan add 10 and 20 also?
Thank you Cristiano F1! Yes, that would improve security.
I like to think about it in terms of how are the devices used. Switches are access client facing and should be able to route, applying ACLs to prevent unauthorized access. Firewalls are default gateways for security filtering. Routers do routing for BGP OSPF etc. Routers you really want on the outside of the network or handling routing tables that’s why router on a stick isn’t really ever used more like firewall on a stick. 4th option is an ASA that can route
Fantastic presentation.
Thank you Dave Dool!
I was configured ROAS method in an enterprise network and the networks goes so slow, then replace with L3 SVI method. After a search, I found that router switching performance is lower than multi-layer switches. Is it true?
Layer 3 switches use dedicated chips (ASICs) to switch and route packets, whereas a traditional router relies on its CPU, that's why L3 switches are faster.
Thanks Dear.. Please keep uploading such a great video
Thank you, I will
Also, Keith is ALL ABOUT multi layer switches. They're crazy expensive, though. I think ROAS is more practical. But I'm not a CCIE, like Keith.
Thanks from Karaganda
Welcome!
I passed some certifications but you video clicked things for me especially when to use router on a stick and trunking
Glad I could help
Great video! The third method is called inter-vlan routing?
Thank you @sabdielisstech5049!
Logically, any IP routing between two different directly connected IP subnets, each one in their own L2 VLAN, could be referred to as "inter-VLAN routing", or more simply, just routing. Either term would work.
@@KeithBarker oh, ok. Thanks!
Keith a little more discussion @ 14:38 frame 62 vlan 0. i know its associated to priority packet but want to hear on what you have to say on vlan 0.
Thank you Network knowledge. Feel free to join my Discord sever. Lots of people there helping each other out. Each Saturday at 10am Pacific I hold my "Office Hour" where learners can ask questions about the topics they are studying. Mostly focusing on Cisco CCNA 200-301 topics. Feel free to join us there live if you are available. Here is the link ogit.online/Join_OGIT_on_Discord
Thanks again Network knowledge!
@@KeithBarker my timing clashes with yours quite unfortunate in that to live chat
Wait, isn't the whole point of a router to break up a broadcast domain? What happens to a broadcast domain if using multilayer switch. ?
Hello Keith
Just wanted to know if your using IOL for your Switches/Routers or if your using vIOS.
Thank you for the question Masenya Rametse. I usually use vIOS, but if I have hundreds of routers, I may use IOL as it is less resource intensive.
Thanks! Which simulation software do you use?
It looks like EVE-NG.
Thank you for the question DevNetWise. This is indeed Eve-NG
Thank you
Thank you Number Thirteen! Was great to see in in the quiz last week!
Can I please be assisted, my end devices are unable to communicate with each other between the vlans but, they can communicate within the same vlan, I did this on packet tracer. What could be the problem?

What program do you use in this video ?
Thank you for the question Евгений Волков. The pen tool is Epic Pen. The emulator is Eve-ng.
Hope that helps, and best wishes!
Hi. What simulator/emulator are you using for your lab?
He’s using Eve-ng. Google search for it. It’s a free download. Though you still have to get your IOS from the vendors
@Shahim, Search for Eve NG on TH-cam and would will find several youtubers with installation instructions and download links. Happy labbing!
Thank you for the question Shahin.
Indeed, for this video it was Eve-NG. (I use the pro edition).
Your content is fantastic, I just wish you could could ease off the crack a bit. Slow down, man. I do love and appreciate your enthusiasm, and eagerness to share.
Keith has probably a hundred great videos over the last decade teaching us all that he’s shared in this video. It’s meant as a quick refresher course on L3 routing, not an introduction to Cisco networking.
