Figure 5-6 illustrates a network using GVRP.
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.
