2-12 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.
