VTP
VLAN Trunking Protocol (VTP) is a network management tool that helps organize and maintain networks in large organizations. Think of it like a master control system that automatically keeps track of virtual networks (VLANs) across multiple network devices. Instead of manually configuring each network device one by one, VTP allows network administrators to make changes in one place and automatically share these changes across all connected devices. It's similar to having a central management system that keeps everything synchronized, like how a company might use a central employee database to update information across all departments.
