• Switch B is the core switch, all others are edge switches
• Ports A1, B1 to B4, C1, D1, D2 and E1 are GVRP aware
• Ports B1 to B4, D1 and D2 are set to advertise and learn
• Ports A1, C1 and E1 are set to advertise only
• Ports A2, C2 and E2 are edge ports
• End node D is GVRP aware
• End nodes A, E and C are GVRP unaware
• Ports A2 and C2 are configured with PVID 7
• Port E2 is configured with PVID 20
• End node D is interested in VLAN 20, hence VLAN 20 is advertised by it towards switch D
• D2 becomes a member of VLAN 20
• Ports A1 and C1 advertise VID 7
• Ports B1 and B2 become members of VLAN 7
