3-12 GARP
The Generic Attribute Registration Protocol (GARP) provides a generic framework that
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.
