Chapter 4 GVRP Configuration

GARP VLAN Registration Protocol (GVRP) is a GARP application. It functions based
on the operating mechanism of GARP to maintain and propagate dynamic VLAN
registration information for the GVRP devices on the network.
When configuring GVRP, go to these sections for information you are interested in:

4.1 Introduction to GVRP
4.1.1 GARP
Generic Attribute Registration Protocol (GARP) provides a mechanism that allows
participants in a GARP application to distribute, propagate, and register with other
participants in a bridged LAN the attributes specific to the GARP application, such as
the VLAN or multicast address attribute.
GARP itself does not exist on a device as an entity. GARP-compliant participants are
known as GARP applications. One example is GVRP. When a GARP participant is
present on a port on your device, the port is regarded as a GARP participant.
I. GARP messages and timers
1) GARP messages
GARP participants exchange information through the following three types of
messages: Join message, Leave message, and LeaveAll message.
A GARP participant uses Join messages to have its attributes registered on other
devices. A GARP participant also sends Join messages to register attributes on
other GARP participants when it receives Join messages from other GARP
participants or static attributes are configured on it.
A GARP participant uses Leave messages to have its attributes deregistered on
other devices. A GARP participant also sends Leave messages when it receives
Leave messages from other GARP participants or static attributes are
deregistered on it.
LeaveAll messages are used to deregister all the attributes, through which all the
other GARP participants begin to have all their attributes registered. A GARP
participant sends LeaveAll messages upon the expiration of the LeaveAll timer,
which is triggered when the GARP participant is created.
