Understanding How VTP Version 1 and Version 2 Work
VTP is a Layer 2 messaging protocol that maintains VLAN configuration consistency by managing the
addition, deletion, and renaming of VLANs on a network-wide basis. VTP minimizes misconfigurations
and configuration inconsistencies that can result in a number of problems, such as duplicate VLAN
names, incorrect VLAN-type specifications, and security violations.
You can use VTP to manage VLANs 1–1005 in your network. (VTP version 1 and VTP version 2 do not
support VLANs 1025–4094.) With VTP, you can make configuration changes centrally on one switch
and have those changes automatically communicated to all the other switches in the network.
