What Does VLAN Trunking Protocol (VTP) Mean?
Virtual local area network (VLAN) trunking Protocol or VTP is a proprietary protocol from Cisco that allows networks to send network functionality through all of the switches in a domain. This technique eliminates the need for multiple configurations for VLANs throughout the system.
Techopedia Explains VLAN Trunking Protocol (VTP)
VTP, which is available with Cisco Catalyst products, provides efficient ways to send a VLAN through every switch. There’s also the option of VLAN pruning which will avoid sending traffic through some switches. Users can make these systems pruning eligible or pruning ineligible.
