Overview of GVRP

Overview of GVRP


The Generic Attribute Registration Protocol (GARP) provides a mechanism for propagating attributes so that a protocol entity can register and deregister attributes. By filling different attributes into GARP packets, GARP supports various upper-layer applications.

The GARP VLAN Registration Protocol (GVRP) is used to register and deregister VLAN attributes.

GARP identifies applications through destination MAC addresses. IEEE Std 802.1Q assigns 01-80-C2-00-00-21 to the VLAN application (GVRP).


To deploy a VLAN on all devices on a network, a network administrator must manually create it on each device. In Figure 12-1, three routers are connected through trunk links. VLAN 2 is configured on Switch A, and VLAN 1 is configured on Switch B and Switch C. To forward packets of VLAN 2 from Switch A to Switch C, the network administrator must manually create VLAN 2 on Switch B and Switch C.

Figure 12-1  GVRP application

When a network is complex and the network administrator is unfamiliar with the network topology, or when many VLANs are configured on the network, the manual configuration workload is enormous. In addition, configuration errors may occur due to human error. GVRP can be configured on the network to implement automatic registration of VLANs, reducing configuration workload and the likelihood of configuration errors.


GVRP is based on GARP. It dynamically maintains VLAN attributes on devices. Using GVRP, VLAN attributes of one device can be propagated throughout the entire switching network. GVRP enables network devices to dynamically deliver, register, and propagate VLAN attributes, reducing the workload of the network administrator and helping to ensure correct configuration.
