Configure Generic Attribute Registration Protocol
Generic Attribute Registration Protocol (GARP) allows network devices to share
information such as VLAN IDs and multicast group membership across a bridged LAN.
That is, GARP participants can register and deregister attribute values within the LAN.
When a GARP participant declares or withdraws an attribute, the attribute value is
recorded for that attribute and for the interface from which the declaration or withdrawal
was made.
The following applies to GARP:
Registration occurs only on interfaces that receive a GARP PDU with a declaration
or withdrawal.
Deregistration occurs only if all GARP participants that are connected to the same
LAN segment as the interface withdraw the declaration.
