Understanding How GVRP Works

GARP and GVRP are industry-standard protocols described in IEEE 802.1p.
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 connected through 802.1Q trunk ports.
