Figure 5-6:Network example using GVRP

In Figure 5-6, Switch A is a member of VLAN Red. VLAN Red has the VLANid 10. Port 1 and port 2 on Switch A are added to the VLAN as untagged.

The configuration for Switch A is as follows:

create vlan red

config vlan red tag 10

config vlan red add port 1-2 untagged

enable gvrp

Switch B does not need to be configured with VLAN or tagging information. Instead, using GVRP, the server connected to Switch B, and the remainder of the network connected to Switch B provide Switch B with the information it needs to forward traffic. Switch A automatically adds port 3 to VLAN Red because Switch A now knows that there are other devices on port 3 that need access to VLAN Red.
