Application Scenarios for GVRP
GVRP enables switches on a network to dynamically maintain and update VLAN information. With GVRP, you can adjust VLAN deployment on the entire switching network by configuring only a few devices. Analyzing the topology and managing configurations are not necessary. In Figure 8-5, GVRP is enabled on all devices. Devices are interconnected through trunk interfaces and each trunk interface allows packets of all VLANs to pass. Using GVRP, you simply need to configure static VLANs 100 to 200 on SwitchA and SwitchB. Other devices can then learn VLANs 100 to 200 using GVRP. Department A then can communicate with Department B. The VLAN deletion is similar.
