GVRP is a GARP application that provides 802.1Q-compliant VLAN pruning and dynamic VLAN creation on 802.1Q trunk ports.
With GVRP, the switch can exchange VLAN configuration information with other GVRP switches, prune unnecessary broadcast and unknown unicast traffic, and dynamically create and manage VLANs on switches that are connected through 802.1Q trunk ports.

Multiple Registration Protocol/Multiple VLAN Registration Protocol is used for dynamically creating
VLANs and/or dynamically adding ports to VLANs. As per IEEE Std 802.1Q-2011, some VLANs can be
marked as forbidden VLANs on some ports so that when MVRP PDU is received on the port with the
particular forbidden VLAN Id, the VLAN is not created and if the VLAN is already there, the port is not
added to the VLAN.
The VLAN registration is of three types:
• Forbidden—Port is forbidden to be added to the VLAN
• Normal—Port is allowed to be added to the VLAN
• Fixed—Port is statically added to the VLAN
