FIGURE 81 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.

• GVRP is enabled on all
ports.
• Both learning and
advertising are
enabled.
NOTE: Since learning is
disabled on all the
edge devices,
advertising on the
core device has no
effect in this
configuration.
