How to work VLAN and VTP?

when the person configures the VLAN into the vtp server it broadcastes into entire domain

VLAN Trunk Protocol (VTP) reduces administration in a switched network. When you configure a new VLAN on one VTP server, the VLAN is distributed through all switches in the domain. ... VTP is a Cisco-proprietary protocol that is available on most of the Cisco Catalyst series products. Vlan can brake  the Brodcast on network .

VLAN Trunking Protocol (VTP) is a Cisco proprietary protocol that propagates the definition of Virtual Local Area Networks (VLAN) on the whole local area network. To do this, VTP carries VLAN information to all the switches in a VTP domain. VTPadvertisements can be sent over 802.1Q, and ISL trunks.

VTP (Virtual Trunking Protocol) once it get configured as server,server will broadcast the vlans into the entire domain and no need to create vlans individually in every switch.only thing we need to do is make other swithces vtp client and server will broadcast the vlan information to clients and it will increase the network performance.

VLAN shares the broadcast domain of switches ‍and increase network performance. VTP (VLAN Trunking protocol) carries multiple vlan information.
