Chart 2 shows an example with two VLANs indicated by red and blue. In this example, frames
broadcast from Port 1 will only go to Port 2 since Ports 3 and 4 are in a different VLAN. VLANs can be
used to divide a network by restricting the transmission of broadcast frames.
Note: In practice, VLANs are distinguished by the use of VLAN IDs.
