1.1.2 GVRP

As an implementation of GARP, GARP VLAN registration protocol (GVRP) maintains
dynamic VLAN registration information and propagates the information to the other
switches through GARP.
With GVRP enabled on a device, the VLAN registration information received by the
device from other devices is used to dynamically update the local VLAN registration
information, including the information about the VLAN members, the ports through
which the VLAN members can be reached, and so on. The device also propagates the
local VLAN registration information to other devices so that all the devices in the same
LAN can have the same VLAN information. VLAN registration information propagated
by GVRP includes static VLAN registration information, which is manually configured
locally on each device, and dynamic VLAN registration information, which is received
from other devices.
GVRP has the following three port registration modes: Normal, Fixed, and Forbidden,
as described in the following.
