Figure 8.1 Example of GVRP
In this example, a core device is attached to three edge devices. Each of the edge devices is attached to other
edge devices or host stations (represented by the clouds).
The effects of GVRP in this network depend on which devices the feature is enabled on, and whether both
learning and advertising are enabled. In this type of network (a core device and edge devices), you can have the
following four combinations:
• Dynamic core and fixed edge
• Dynamic core and dynamic edge
• Fixed core and dynamic edge
• Fixed core and fixed edge
Dynamic Core and Fixed Edge
In this configuration, all ports on the core device are enabled to learn and advertise VLAN information. The edge
devices are configured to advertise their VLAN configurations on the ports connected to the core device. GVRP
learning is disabled on the edge devices.
