GARP VLAN Registration Protocol (GVRP) is a Generic Attribute Registration Protocol (GARP) application that
provides VLAN registration service by means of dynamic configuration (registration) and distribution of VLAN
membership information.
An HP device enabled for GVRP can do the following:
• Learn about VLANs from other HP devices and configure those VLANs on the ports that learn about the
VLANs. The device listens for GVRP Protocol Data Units (PDUs) from other devices, and implements the
VLAN configuration information in the PDUs.
• Advertise VLANs configured on the device to other HP devices. The device sends GVRP PDUs advertising
its VLANs to other devices. GVRP advertises statically configured VLANs and VLANs learned from other
devices through GVRP.
GVRP enables an HP device to dynamically create 802.1Q-compliant VLANs on links with other devices that are
running GVRP. GVRP reduces the chances for errors in VLAN configuration by automatically providing VLAN ID
consistency across the network. You can use GVRP to propagate VLANs to other GVRP-aware devices
automatically, without the need to manually configure the VLANs on each device. In addition, if the VLAN
configuration on a device changes, GVRP automatically changes the VLAN configurations of the affected devices.
The HP implementation of GARP and GVRP is based on the following standards:
• ANSI/IEEE standard 802.1D, 1998 edition
• IEEE standard 802.1Q, 1998 edition; approved December 8, 1998
• IEEE draft P802.1w/D10, March 26, 2001
• IEEE draft P802.1u/D9, November 23, 2000
• IEEE draft P802.1t/D10, November 20, 2000

Application Examples

Figure 8.1 shows an example of a network that uses GVRP. This section describes various ways you can use
GVRP in a network such as this one. "CLI Examples" on page 8-16 lists the CLI commands to implement the
applications of GVRP described in this section.
