VLAN Trunking Protocol (VTP)

VLAN Trunking Protocol (VTP) is a networking protocol used in Ethernet networks to manage Virtual Local Area Networks (VLANs) efficiently. It allows network devices, like switches, to share information about VLAN configurations automatically. This means that when changes are made, such as adding or deleting a VLAN, they are communicated across all connected devices, keeping the network settings consistent. VTP simplifies network management and helps maintain organization within larger networks by ensuring all switches have the same VLAN information without requiring manual updates for each device.
