3-12. GVRP
The GARP (Generic Attribute Registration Protocol) VLAN Registration Protocol (GVRP) defines
a GARP application that provides the 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
VLAN’s on switches connected through 802.1Q trunk ports.
GVRP makes use of GID and GIP, which provide the common state machine descriptions and the
common information propagation mechanisms defined for use in GARP-based applications.
GVRP runs only on 802.1Q trunk links. GVRP prunes trunk links so that only active VLAN’s will
be sent across trunk connections. GVRP expects to hear join messages from the switches before
it will add a VLAN to the trunk. GVRP ports run in various modes to control how they will prune
VLAN’s. GVRP can be configured to dynamically add and manage VLANS to the VLAN database
for trunking purposes.
