GVRP application examples
The Brocade implementation of GARP and GVRP is based on the following standards:
ANSI/IEEE standard 802.1D, 1998 edition
IEEE standard 802.1Q, 1998 edition; approved December 8, 1998
IEEE draft P802.1w/D10, March 26, 2001
IEEE draft P802.1u/D9, November 23, 2000
IEEE draft P802.1t/D10, November 20, 2000
GVRP application examples
Figure 108 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. “GVRP CLI examples” on page 902 lists the CLI
commands to implement the applications of GVRP described in this section.
FIGURE 108 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
