This really helped me. I passed CCNA and work as a network engineer and still find myself thinking "Frame or packet??". This is really clear and helpful. Thank you. Just subscribed too.

Was looking for something to explain this to a colleague. This fit perfectly. Thankyou. One NitPick: around the 6:00 point, you decapsulate the IP packet from the Ethernet Frame, then put it back into the same Frame. I think it would be clearer if you scrap the old Frame and create a new one with Src-MAC of the router port and the Dest-Mac of the final host. Still one of the clearest videos i could find online. Thanks!

@kelvin513 4 жыл бұрын

Thanks Jacob. This explain how the switch and router works together to communicate. I am studying my materials for CCNA and the tutor just doesn’t mentioned the encapsulation and decapsulation of it.

This was exactly what I needed. I am a Junior Datacenter Architect covering HCI and Virtualization. and Its been hell trying to learn just enough of the other categories, such as networking without spending a ridiculous amount of time doing those certifications. This video covered exactly what i needed to know, and explained it as if i am coming from nothing.

FINALLY!!! I've taken tons of college classes and even tried the Cisco CCNA program last year and could never quite make sense out of this process until now! Why is it so hard for so many professionals to break it down like this where the process makes sense? Cisco should let you overhaul their program! Subscribed!

@j.t.8475 4 жыл бұрын

HONESTLY, I'm in college right now and its a class I need to take. I'm in the netcad Cisco program but honestly its not this clear and simple!!! These videos help me understand it so clearly and simple compared to that cisco class/course!! Wish me luck!

@gareginasatryan6761 4 жыл бұрын

Deez Skates the latest CCNA does go into visualizing how frames get forwarded in a network quite extensively. I agree with you that nailing it down is absolutely crucial in understanding networks, especially from a troubleshooting perspective. To give an example. One time, random hosts on the LAN were getting a 169 address. My boss told me that it’s probably the switch or the cabling. But I was explaining it to him that it has something to do with the firewall (dhcp server). Because a bad uplink cable would cut off everyone. You can’t have some hosts working and some not on a faulty ethernet cable, because the frames are multiplexed across a single pair of wires. The example is to illustrate that troubleshooting requires understanding the details of the technology. Also another time it happened, he was fiddling with the modem. I explained to him that a bad WAN connection can’t cut off your local IP address assignments.

finally i understood how the mac is used in combination with ip. Thank you very much. And for those wondering how to obtain the MAC/IP combination of local device (eg. the gateway), the answer is the Access Resolution Protocol (ARP). for a practical overwiev in Windows: open commandline (cmd or powershell ) and run first IPCONFIG and afterwards ARP -A

But there is one thing I don't understand : In this video the default gateway is in your house. But your gateway does not know the destination mac adress, yet in this video he says it does? I think only the router in the destinations network knows the final destination mac address??

@SystemHacker23 2 жыл бұрын

Hear me out with this analogy. I see this as me sending out a letter (packet), which in this case my computer IP is my address, and the recipient's IP is where the letter is addressed to. Before I can send it I package the envelope into a FedEx box that has the FedEx tracking number (the Mac address). Once the package is received to the truck driver (the network), he scans the tracking number and takes it to the warehouse (router). The only deviation here is that the warehouse takes that tracking number, and assigns it a new one (other Mac address, which is now picked up and scanned by a second truck driver (2nd network) to get it delivered to the new address (2nd Mac address). The recipient then opens the package to find his name on it (his IP address). Hope this helped and not confused anyone.

A hint, when you box, unbox the data => packet => frame => wire , you could draw horizontal lines with the OSI Layers. this way its easy to understand why switches operate with frames at Layer 2, Routers at Layer 3 with packets, and your (skype/whatever app) at top Layer with Data.
