more efficiently within subgroups.
VLANs use software to reduce the amount of time it takes for network
changes, additions, and moves to be implemented.
VLANs can be created per unit, per device, or through any other logical
connection combination, since they are software-based and not defined by
physical attributes. VLANs function at Layer 2. Since VLANs isolate traffic
within the VLAN, a Layer 3 router working at a protocol level is required to
allow traffic flow between VLANs. Layer 3 routers identify segments and
coordinate with VLANs. VLANs are Broadcast and Multicast domains.
