What is VLAN Trunking Protocol (VTP) Domain

The VLAN Trunking Protocol (VTP) is organized into management domains. A VLAN Trunking Protocol (VTP) domain is one switch or several interconnected switches sharing the same VLAN Trunking Protocol (VTP) environment. A switch can be configured only in one VLAN Trunking Protocol (VTP) domain. Switches in different VTP domains do not share VLAN Trunking Protocol (VTP) information.

Switches in a VLAN Trunking Protocol (VTP) domain advertise many VLAN attributes to their VLAN Trunking Protocol (VTP) domain neighbors. These VLAN advertisements contain information about the VTP management domain, VTP revision number, available VLANs, and other VLAN parameters.
