Application examples

Figure 110 shows an example of a network that uses GVRP. This section describes various ways

you can use GVRP in a network such as this one. “CLI examples” on page 522 lists the CLI

commands to implement the applications of GVRP described in this section.

FIGURE 110 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.
