Cisco - CCENT/CCNA R&S (100-105) - Why VLANs? Overview/Introduction .21

Twenty first Video in a Series covering all elements of The Cisco Certified Entry Networking Technician (CCENT) 100-105 ICND1v3 which is the first part of the CCNA certification.

Blueprint Section: LAN Switching Fundamentals

Now we have the fundamental of how a switch processes incoming frames to the correct interface(s) we start to dive into some of the more complex LAN topics starting with VLANS!

In this video, we start by reviewing the challenges with networks which do not implement the VLANs and how these are resolved or improved when bringing VLANs into the network design.

In our next video, we’ll continue with VLANs, understanding the difference between trunk ports, access ports and creating VLANs

Your tutorials are truely exceptional, they provide such a nice combination of theory along with the practical problem. Thank you very much. With each lecture I feel I understand well about the subject and feel not boring at all about all these otherwise hard-to-crack stuff. Thank you.

Comming from the Architecture side, I find your overview excellent. You blanket a very broad and important subject of the Networking realm. @ this point is where the purpose of the networking world comes to show the tools of the trade. Great work Ryan!

Thanks for your attention to detail! Really illuminating!

Nice video, so it's VLAN purposes and the relation between Broadcast domain, subnet and VLAN .

I have gone through the first 5 videos of this series, am enjoying and plan to continue, but curious if 21 is the last in the series or where you have gotten with it so far? thank you

So what are the security limits of creating a vlan through a switch (if I am getting my terminology correct, ) or choosing to run the lan through a router? I am hearing that a router creates a higher degree of security. So, using the HR server as an example, one wouldn't want to break up a switch into vlans because it would not be as secure as running one's network through a router? I guess I am asking to what degree is running one's vlan through a router more secure than just dividing up a switch?
