1.1.1 Introduction to GARP
Generic Attribute Registration Protocol (GARP) offers a mechanism that is used by the
members in the same switching network to distribute, propagate and register such
information as VLAN and multicast addresses.
GARP dose not exist in a switch as an entity. A GARP participant is called GARP
application. The main GARP applications at present are GVRP and GMRP. GVRP is
described in the section
Configuration. When a GARP participant is on a port of the switch, each port
corresponds to a GARP participant.
Through GARP mechanism, the configuration information on one GARP member will
be advertised rapidly in the whole switching network. GARP member can be a terminal
workstation or bridge. A GARP member can notify other members to register or remove
its attribute information by sending declarations or withdrawal declarations. It can also
register or remove the attribute information of other GARP members according to the
received declarations/withdrawal declarations.
GARP members exchange information through sending messages. There are mainly
three types of GARP messages including Join, Leave, and LeaveAll.
When a GARP participant wants to register its attribute information on other
switches, it will send Join message outward.
When it wants to remove some attribute values from other switches, it will send
Leave message.
LeaveAll timer will be started at the same time when each GARP participant is
enabled and LeaveAll message will be sent upon timeout.
The Join message and the Leave message are used together to complete the
deregistration and re-registration of information. Through exchanging messages, all
the attribute information to be registered can be propagated to all the switches in the
same switching network.
GVRP Mechanism and GMRP will be described in Multicast
