applications. MVRP provides a mechanism for dynamic maintenance of the contents of dynamic VLAN registration entries for each VLAN, and for propagating the information they contain to other bridges. This information allows MVRP-aware devices to establish and update dynamically their knowledge of the set of VLANs that currently have active members, and through which ports those members can be reached. The main purpose of MVRP is to allow switches to automatically discover some of the VLAN information that would otherwise need to be manually configured.

GARP was defined by the IEEE 802.1 working group to provide a generic framework allowing bridges (or other devices like switches) to register and de-register attribute values such as VLAN identifiers and multicast group membership. GARP defines the architecture, rules of operation, state machines and

Multiple MAC Registration
Protocol is a data link layer (layer 2) protocol to register group MAC addresses (i.e. multicast) on multiple switches. It is an MRP application, originally defined in IEEE 802.1ak-2007 and subsequently included in 802.1Q. It replaced the 802.1D based GMRP. The purpose of
163:
Within a layer 2 network, MVRP provides a method to dynamically share VLAN information and configure the needed VLANs. For example, in order to add a switch port to a VLAN, only the end port, or the VLAN-supporting network device connected to the switchport, need be reconfigured, and all necessary
187:
MVRP defines a MRP application that provides the VLAN registration service. MVRP makes use of MRP Attribute
Declaration (MAD) and MRP Attribute Propagation (MAP), which provide the common state machine descriptions and the common information propagation mechanisms defined for use in MRP-based
196:
The replaced GVRP was essentially the same thing, but it used the services of the 802.1D based GARP application. GVRP made use of GARP Information
Declaration (GID) and GARP Information Propagation (GIP), which correspond to the MAP and MAD in MRP. It was defined in the original release of
121:). This change essentially moved the definitions of GARP, GVRP, and GMRP into an 802.1Q based environment, implying they were already VLAN aware. This also allowed for significant streamlining of the underlying protocol without much change to the interface of the applications themselves.
124:
The new protocol and applications fixed a problem with the old GARP-based GVRP-based system, where a simple registration or a failover could take an extremely long time to converge on a large network, incurring a significant bandwidth degradation.

VLAN trunks are dynamically created on the other MVRP-enabled switches. Without using MVRP, either a manual configuration of VLAN trunks or use of a manufacturer's proprietary method is necessary.
167:
It is through MVRP that dynamic VLAN entries will be updated in the filtering database. In short, MVRP helps to maintain VLAN configuration dynamically based on current network configurations.
183:
Combined static and dynamic configuration, in which some VLANs are configured via management mechanisms and for other VLANs, MVRP is relied on to establish the configuration.
