In modern networking, Virtual LANs (VLANs) play a crucial role in segmenting networks for improved security, efficiency, and manageability. In. You will need to configure trunks on each switch in order for them to carry multiple VLANs. I think VTP is what you mean by. This post will deal with creating Layer 2 VLANs on Cisco switches and performing all relevant configurations. A broadcast message generated in one VLAN does not reach another VLAN.
