This function includes three options,
GARP, GVRP
and
GMRP.

P
rotocol, also known as Multiple Registration Protocol
(MRP). It operates at the data link layer of OSI, and it defines the architecture, rules of
operation, state machines and variables for the registration and removing of attribute values.
GARP is used by two applications:
GARP VLAN Registration Protocol
(
GVRP
), and
GARP Multicast Registration Protocol
(
GMRP
). GVRP provides a method to share VLAN
information dynamically and configure the needed VLANs. GMRP provides a mechanism
that allows bridges and switches to register trunking information dynamically. GVRP and
GMRP are similar, and the only difference is that GVRP works with VLAN but GMPR works
with Multicast MAC address.
