So that they can have multiple networks on the same LAN. I don't think in a business capacity, you would want to have a lot of broadcast traffic because there's over thousands of machines connected to the same LAN. In a business or enterprise environment, you'd use layer 2 managed or layer 3 switches.
VLANs would be setup on a switch(es) to divide/segment the entire network into smaller networks or subnets. In the case of a layer 2 switch, the VLANs are then trunked to a router or layer 3 switch for inter-vlan routing. With a layer 3 switch, inter-vlan routing can be done on the switch as routing happens at layer 3 (network layer of OSI model).
Theres other reasons to split up a network besides broadcast traffic, but broadcast traffic is one reason. |
