Configuring GVRP
1

Overview

GVRP (GARP VLAN Registration Protocol) is a GARP (Generic Attribute Registration
Protocol) application that allows registration and deregistration of VLAN attribute values
and dynamic VLAN creation.
Without GVRP operating, configuring the same VLAN on a network would require manual
configuration on each device. As shown in Figure 1-1, Switch A, B and C are connected
through trunk ports. VLAN 10 is configured on Switch A, and VLAN 1 is configured on
Switch B and Switch C. Switch C can receive messages sent from Switch A in VLAN 10 only
when the network administrator has manually created VLAN 10 on Switch B and Switch C.
Figure 1-1 VLAN Topology
The configuration may seem easy in this situation. However, for a larger or more complex
network, such manual configuration would be time-consuming and fallible. GVRP can be
used to implement dynamic VLAN configuration. With GVRP, the switch can exchange
VLAN configuration information with the adjacent GVRP switches and dynamically create
and manage the VLANs. This reduces VLAN configuration workload and ensures correct
VLAN configuration.
