1.2.13 GARP
The Generic Attribute Registration Protocol (GARP) provides a generic framework whereby devices
in a bridged LAN, e.g. end stations and switches, can register and de-register attribute values, such
as VLAN Identifiers, with each other. In doing so, the attributes are propagated to devices in the
bridged LAN, and these devices form a reachability tree that is a subset of an active topology. GARP
defines the architecture, rules of operation, state machines and variables for the registration and de-
registration of attribute values.
A GARP participation in a switch or an end station consists of a GARP application component, and a
GARP Information Declaration (GID) component associated with each port or the switch. The
propagation of information between GARP participants for the same application in a bridge is carried
out by the GARP Information Propagation (GIP) component. Protocol exchanges take place between
GARP participants by means of LLC Type 1 services, using the group MAC address and PDU format
defined for the GARP application concerned.
