GVRP is defined in the IEEE 802.1Q standard, and GARP is defined in the IEEE 802.1D-1998 standard. To understand and use GVRP you must have a working knowledge of 802.1Q VLAN tagging. (Refer to chapter 2, "Static Virtual LANs (VLANs)" .) GVRP uses "GVRP Bridge Protocol Data Units" ("GVRP BPDUs") to "advertise" static VLANs. In this manual, a GVRP BPDU is termed an advertisement. Advertisements are sent outbound from ports on a switch to the devices directly connected to those ports. GVRP enables the switch to dynamically create 802.1Q-compliant VLANs on links with other devices running GVRP. This enables the switch to automatically create VLAN links between GVRP-aware devices. (A GVRP link can include intermediate devices that are not GVRP-aware.) This operation reduces the chances for errors in VLAN configuration by automatically providing VLAN ID (VID) consistency across the network. That is, you can use GVRP to propagate VLANs to other GVRP-aware devices instead of manually having to set up VLANs across your network. After the switch creates a dynamic VLAN, you can optionally use the CLI static command to 3-3
