VTP ensures that all switches in the VTP domain are aware of all VLANs.
Most of the VTP packets contain the VTP configuration revision number of the sender.
Changing the VTP version from 1 to 2 will not cause a switch to reload.
Each network device in the VTP domain sends periodic advertisements out each trunking LAN interface to a reserved multicast address.
