7.8 GVRP
GVRP (GARP VLAN Registration Protocol) is an implementation of GARP (generic attribute
registration protocol). GVRP allows the switch to automatically add or remove the VLANs via the
dynamic VLAN registration information and propagate the local VLAN registration information to
other switches, without having to individually configure each VLAN.
GARP
GARP provides the mechanism to assist the switch members in LAN to deliver, propagate and
register the information among the members. GARP itself does not work as the entity among the
devices. The application complied with GARP is called GARP implementation, and GVRP is the
implementation of GARP. When GARP is implemented on a port of device, the port is called
GARP entity.
The information exchange between GARP entities is completed by messages. GARP defines the
messages into three types: Join, Leave and LeaveAll.
