Virtual Local Area Networks (VLANs) are used in almost every single network in the world, even homes and businesses need and use Virtual LANs (VLANs). This short, fun-filled, and fact-filled video by Todd Lammle provides the insight you need to follow and understand the VLAN videos in this series.
- I know I keep telling you this,…but so you never forget it…here I go one last time.…By default switches break up collision domains…and routers break up broadcast domains.…In contrast to the networks of yesterday…that were based on collapsed backbones,…today's network design is characterized by…a flatter architecture…thanks to switches.…So now what?…By creating Virtual Local Area Networks or VLANs…we break up a broadcast domain…in a pure switched internetwork.…
A VLAN is a logical grouping…of network users and resources connected…to administratively defined ports on a switch.…A VLAN is treated like its own subnet or broadcast domain.…Meaning that frames broadcasted onto the network…are only switched between the ports…logically grouped within the same VLAN.…When you create VLANs you're given the ability…to create smaller broadcast domains…within a layer 2 switched internetwork…by assigning different ports on the switch…to different subnetworks.…Does this mean we no longer need routers?…It really depends on what your…
