Question

What's is VTP?

Accepted Answer

VTP stands for VLAN Trunking Protocol. It is a Cisco proprietary protocol used to manage VLAN configurations across a network.

VTP allows for centralized management of VLANs in a network.
It enables the creation, deletion, and renaming of VLANs on a switch and automatically propagates these changes to other switches in the network.
VTP operates in three modes: server, client, and transparent.
Server mode allows VLAN configuration changes, client mode receives and stores VLAN information, and transparent mode forwards VTP advertisements but does not synchronize VLAN configurations.
VTP advertisements are sent as multicast frames using Ethernet Type 0x8100.
VTP version 3 introduced enhanced security features like authentication and support for extended VLANs.
