VLAN Trunking Protocol
VLAN Trunking Protocol (VTP) gives engineers a convenient way to distribute some VLAN configuration information among switches. VTP defines a messaging protocol and related processes, so that VLAN configuration made on one switch is then advertised to other switches.

Then, VTP, running on all the switches, would send messages so that the other 39 switches could dynamically learn the configuration using VTP.
