Description
Generic Attribute Registration Protocol (GARP)
Complete Definition
The Generic Attribute Registration Protocol (GARP) was defined by the IEEE to provide a generic framework so bridges (or other devices like switches) could register and de-register attribute values, such as VLAN identifiers and multicast group membership. GARP defines the architecture, rules of operation, state machines and variables for the registration and de-registration of attribute values. GARP is the protocol used by the VLAN management protocol (GVRP: GARP VLAN Registration Protocol) for trunking between multilayer switches, and by the GARP Multicast Registration Protocol ([[GMRP]).
The IEEE 802.1D standard mentions the idea of dynamic registration of 'group membership' between MAC bridges.
In recent times, multilayer switches, which primarily combine OSI Layer 2 and Layer 3 functionality, can use GVRP to dynamically manage VLAN registration.
