[@Ghent2007]

Very clear explanation, thank you!

[@jacobalexander560]

Love this channel. Ordinarily, these topics are boring and dry. However, your animated videos brings the topics to life, and makes them enjoyable to watch. Thank you!

[@PowerCertAnimatedVideos]

Glad you like them!

[@jucaguima]

Agree

[@nijatrzayev9962]

100% correct, and explained and animated in a way that even kids can understand.

[@legendarygreatness1]

True‼️‼️

[@Hudsonn86]

100% true. This channel help me a lot

[@NandoP07]

Like I've said before, I think, this channel deserves a lot more recognition. Even for a non-native english speaker, your videos are really really well explained. Thanks for your effort!

[@PowerCertAnimatedVideos]

Thanks! 😃

[@goofball1_134]

Passed my server+ exam a week ago partially with the help of videos like these. For once I already knew most of the topic of this video which is awesome. Thanks powercert for all your videos, they're always very well explained.

[@PowerCertAnimatedVideos]

Great to hear!

[@Sylvan_dB]

Nice summary. You touched here on the difference between a Layer 3 switch and a router. I think a full 5-10 minute video on this topic would be helpful. Questions might include: Why would I choose one vs. the other? Advantages/disadvantages relative to the other?

[@RandomFaxx]

yes

[@Asto508]

There is none. Every device that is called "router" is doing layer 3 routing and forwarding. Back when I was young, the term "switch" really just meant layer 2 and especially to distinguish it from "hub" which didnˋt have a proper forwarding mechanism based on destination MACs but simply forwarded frames to every conncted device. This video muddles the differences quite a bit.

[@broodjenoodles]

​@@Asto508layer 3 switch is not a router... It doesnt support natting I thought

[@Asto508]

@@broodjenoodles Layer 3 is referring to the Network Layer which is very commonly the IP layer in most networks and forwarding IP packets is what has been called "routing" since the dawn of time because Layer 3 is the first layer where you actually can have multi-hop routes that require determining the actual path through the network, hence the name Network Layer. Layer 2 is point-to-point only. NATing is basically just a hack to solve the limited 32bit IP address range in IPv4. Even if a router doesn't support it, it's still a router as it handles Layer 3 traffic.

[@broodjenoodles]

@@Asto508 if you call everything that gives out dhpc leases a router...

[@TEAMPHY6]

My homeschooled middle schoolers are going through each of your 90+ videos and writing reports on them. Thanks for the resource and breaking it down so anyone can understand.

[@PowerCertAnimatedVideos]

Happy to help!

[@MrGenericmember1234]

Best IT videos on the internet! The simple visualizations make understanding the topics so much easier. Thanks :)

[@nightwingx6]

Incredibly helpful and informative video, as always! I’ve referenced your videos so many times over the years and it’s great to see that you are still making them. Thank you so much for your service to the community.

[@PowerCertAnimatedVideos]

Glad you like them!

[@recalion]

Best video about this topic I have seen so far. Clear, short and concrete.

[@Mister6]

Man you do such a great job of simplifying these technologies! Your content should be mandatory learning in most Networking and IT courses

[@shann2197]

This is the best channel to learn IT I've ever seen by far. Can understand absolutely anything the way you explain stuff in your videos.

[@mindingplus2783]

I love this channel. It short, simple , well animated and not overwhelming. Well done 👍

[@SHO1989]

As always, excellent and thank you. Man, I wish I had these videos 20 years ago when I was starting my IT career.

[@blacklight492]

I hope you never stop making videos! They are so helpful!

[@I2esist]

The way you explain topics in such a easy to comprehend manner is second to none, you should write a book! You have helped me tremendously in my journey in the IT world, thank you 🙏🏻

[@Choppd35]

I could never understand these topics, until I found your channel.. THANKS!✊

[@MacroAggressor]

A good L3 Switch vs Router video would be useful as well.

[@RolandLyngvig]

You simply explained L2 vs L3 switches in a SO easy, precise, and short way. Thanks.

[@chideraezenekwe461]

This is the networking crash course gold mine I've been looking for

[@chansaechao79]

Love the way this is broken down and only the most useful information is presented. It's so much easier to understand the details. Thank you kind sir 🙏

[@waynezahra9213]

I'm now an official member of this wonderful channel. Thank you so for the intel. You have helped me out tremendously.

[@wannabedal-adx458]

Great video, thanks for clearing this distinction up. I have heard of the two types of switches at work but never understood the final details. My only question (or critique) would be if you extended the comparison table at the end to compare the difference between a Layer 3 switch and a Router. You mentioned that Layer 3 switches can't do everything that a router does, so cliffhanger!! Plus it would make for a good review of what exactly a router does. Thanks

[@robertoghinato5754]

I've learned something new today, without getting bored! 5 stars deserved sir 👍🏾

[@JerryPena]

Love the content. Been waiting for new videos. One of the best visual education on KZbin!!

[@TehDipiinDots]

Another video that just makes so much sense!!! I'm studying for my Network + at the moment and absolutely love your videos, as they helped me with my 1101/1102 A+.

[@hvanmegen]

Very good quality explanation; very adequate and clear animations, I love it.. subbed, upvoted and shared!

[@MailonOfficialDR]

What a simple way to explain something that could be complicated! Just like resuming a 100 pages book in 10.

[@bitslammer]

Fantastic overview with excellent visuals to illustrate the concepts.

[@mr2octavio]

Your videos are amazing and I'm so thankful they're provided for free. Thanks!

[@theberna9780]

As always accurate in a few minutes of video. Beautiful! I’ll tell you, you could also make it slightly longer and make them more complete but also like this is perfect

[@being.human119]

Superfast method to learn about these topics.....hats off you sir for your hard work

[@ozzie_goat]

Babe wake up, powercert just uploaded

[@karmakanic475]

Great tutorial, thank you for sharing the knowledge. I really love how simple and demonstrative your explanation is.

[@javacup912]

Great video and simple explanation. Brings back memories from myold CCNP days.

[@jeruvy]

Extraordinarily great video. Simple subject but concise, short and with the visualization it is easy to follow. Thank you for your effort.

[@jean-sebastienfrenette5169]

If only school would teach it this easy

[@patrickcataldo2121]

My apprenticeship school in Germany pretty much did teach me this in the same way. I liked it a lot

[@weekendwarrior3420]

Nice. Answered my question without BS.

[@andreyklepikov7084]

You have a talent to explain complex stuff!!!

[@insight997]

In my IT career with more than 20 years I think this is the most simplest way which explained that any one can understand the most interesting part is your graphical representation which takes me 20 years back nostalgia😊

[@galenmerrick]

I love this channel. Whenever I break through into cyber. I'm definitely donating. Sir, you make the boring, fun.

[@BenyBenator]

Very well explained and animated. Amazing production value

[@PowerCertAnimatedVideos]

Much appreciated!

[@RoyalDog214]

As always, your video is very informative. Thank you for continuing on producing these kind of contents.

[@Photoshopuzr]

This guy is the best guy when it comes to this kind of information, thanks man. very simple and straight to the point no showing off or personal entertainment.

[@tongzhouwarrior]

Thank you for a nice and clean language with a powerful representation of this subject. I liked and subscribed.

[@ane5227]

last time i seen this channel only have 100k subs, now it have 1.4m just a couple years, amazing!

[@Junito973]

You should create a Network+ or CCNA KZbin courses like this, with all the detailed animation. It’s real helpful. Just an idea 😎 you can be the next Professor Messer.

[@user-ks9yc2ch7t]

big thanks for your's animated video!

[@apdj94]

I know nothing about networking but I stayed and watched the whole thing cause it was just that well made

[@galfawker339]

The first channel that nobody comes on screen and bloat a ton of bs before revealing bit of information.

[@johnhill2801]

Great channel. watched every sigle video. Keep up the excellent work.

[@sallai97]

your content is pure gold 🤟

[@aicnedvasquez]

Superb! You helped me saving money. I was going to buy a L3 switch. Now, thanks to you, it's unnecessary! THANK YOU VERY MUCH!

[@RunOs3]

Excellent work. Thank you so much for taking the time.

[@rameshnambi]

Crystal clear explanation brother.

[@michaelpietrzak2067]

Great stuff!

[@Maisonier]

Amazing video! liked and subscribed.

[@Goldsilvern]

I had an epiphany watching this video. Years of knowledge suddenly fit together like a puzzle for me.Seriously. Subnetting and masks make sense after watching this along with VLANS and I’ve been to school and have certs because I was able to regurgitate facts I had memorized about networking never truly understanding how it all fit together.

[@gekkehenkie0001]

Very informative, Thanks!

[@extremelydave]

Always interesting stuff on this channel.

[@markodarabosh9045]

I have watched all of your videos in one week, thank you, I have decided to begin learning networking, because I am tired of outsourcing other people to do that in my company and then that people didnt gave me access to my routers. Do you have more complex lectures on your members channel or do you know any beginner friendly literature for more complex networking?

[@growman5061]

Please make video on unicast vs broadcast vs multicast vs anycast vs incast ??

[@itninja9503]

would love to see an animation and description on how that works with stacked Layer 3 switches.

[@rahultist]

Thankyou for this valuable content 😊

[@aidanbrennan7389]

Great explanation, with graphics!

[@angeloc700]

Excellent info!!

[@PowerCertAnimatedVideos]

Glad it was helpful!

[@TonTonTon140]

Love these videos. Automatic thumbs up!

[@jeaniepearl793]

You dissected this so well, kudos. When it comes to L2, I would say that Mode Network is set apart. Their immediate goal is to establish a robust foundation for a leading Layer 2 platform.

[@humayunchaudhary9267]

i really appreciate your content

[@selimahmed2569]

Clear concept ❤

Best Video about this on KZbin!!!

[@vicrod74]

As always, well explained!!

[@rcstl8815]

This vid made me realize I have two switches that are around 20 years old. They still work. Oh yeah, new subscriber for you.

[@tenaciouspete]

This was a great video. Thanks for the clear explanation

[@William3143]

Excelent vídeo!

[@Tempestelterna]

This takes me back to my networking days! 🎊

[@pvman2]

So, now I'm a bit confused. I've experienced layer 2 switches isolate traffic using tagging; by using tags, especially Port Virtual LAN (VLAN) IDentification (PVID) tags. Can layer 3 switches also do the same without actually creating the Network VLANs as I've experienced the layer 2 switches perform? If so, what is the advantage/disadvantage of performing PVID tagging and trunking vs. Network VLANs as you illustrated for layer 3 switches.

[@raphaelcharlespinon]

Great video. Now you got me interested on what the capabilities Routers have that Layer 3 Switches don't.

[@SpaceCadet4Jesus]

Passing packets between different IP networks, monitoring and protecing inputs (think firewall), interfacing onto your ISP device (Gateway), acting as your ISP device, etc..etc...yawn...🥱

[@charlesAcmen]

Oh my god，u uploaded video when i can still catch on u😂，man ur consistent，keep it up！！

[@user-vu9hs5zu9y]

Excellent video like always. For inter-vlan routing to work does each Vlan require its own default gateway IP or is it just the L3 switch default gateway?

[@asifsartaj7210]

Good explanation. Much appreciated

[@ehsnils]

By the way - consider making a video on port isolation too - that could be useful knowledge too. As an example clients on a network shouldn't normally be able to have intercommunication. That way you could make it harder for an intruder to penetrate workstations. It might not help protecting the servers, they have to be protected by other means. If you have port isolation between clients and have the servers on a different subnet with firewall protection of the clients so that infected servers can't reach the clients then you have an improved technical solution that could create a stronger protection against ransomware worms. I hope that I'm not too complex now though.

[@ianf123]

Great video. One small correction: high end enterprise and service provider switches can have routing functionality comparable to a dedicated router, but generally you’re right. They’re also eye watering expensive. 🤣

[@chandanmukherjee157]

Outstanding ❤❤❤

[@TheRailwayDrone]

I love this channel.

[@ZHNetverse]

Thanks a bunch for this great video!

[@RonaldSaur]

I really liked this video, great over view

[@funkykong9001]

I’m confused why you’d set up VLANs for isolation and then bypass that isolation with a layer 3 switch. Unless you want to allow just some access between hosts in the different VLANs?

[@eribaik]

Protect this channel at all cost guys!

[@ziedux]

Static routing is supported by almost all the recent Layer 2 switchs, they are sometimes called "Layer 2 Plus" switchs (L2+). Nowadays, what's called "full layer three switch", is a switch that can do dynamic routing (For campus switchs it's mainly OSPF, ...) If you're setting up a new campus network, even the access and distribution switchs should be full layer 3 (no more layer 2 and layer 2+), ...

[@andreagagliardini8621]

Excellent explanation. Thank you very much

[@CamperCroftTecnoTips]

amazingly easy to understand thanks !
