What is VTP? • The VLAN Trunking Protocol The VLAN Trunking Protocol (VTP) (VTP) allows you to simplify the allows you to simplify the management of the VLAN database management of the VLAN database across multiple switches across multiple switches . . • As the number of switches increases on a small- or medium- As the number of switches increases on a small- or medium- sized business network, the overall administration required to sized business network, the overall administration required to manage VLANs and trunks in a network becomes a manage VLANs and trunks in a network becomes a challenge. challenge.
