Configuration procedure
1. Configure Device A:
# Enable GVRP globally.
<DeviceA> system-view
[DeviceA] gvrp
# Configure port GigabitEthernet 1/0/1 as a trunk port, and assign it to all VLANs.
[DeviceA] interface gigabitethernet 1/0/1
[DeviceA-GigabitEthernet1/0/1] port link-type trunk
[DeviceA-GigabitEthernet1/0/1] port trunk permit vlan all
# Enable GVRP on GigabitEthernet 1/0/1, and set the GVRP registration mode to forbidden on
the port.
[DeviceA-GigabitEthernet1/0/1] gvrp
[DeviceA-GigabitEthernet1/0/1] gvrp registration forbidden
[DeviceA-GigabitEthernet1/0/1] quit
# Create VLAN 2 (a static VLAN).
[DeviceA] vlan 2
[DeviceA-vlan2] quit
2. Configure Device B:
# Enable GVRP globally.
<DeviceB> system-view
[DeviceB] gvrp
# Configure port GigabitEthernet 1/0/1 as a trunk port, and assign it to all VLANs.
[DeviceB] interface gigabitethernet 1/0/1
[DeviceB-GigabitEthernet1/0/1] port link-type trunk
[DeviceB-GigabitEthernet1/0/1] port trunk permit vlan all
# Enable GVRP on GigabitEthernet 1/0/1, and set the GVRP registration mode to forbidden on
the port.
[DeviceB-GigabitEthernet1/0/1] gvrp
[DeviceB-GigabitEthernet1/0/1] gvrp registration forbidden
[DeviceB-GigabitEthernet1/0/1] quit
# Create VLAN 3 (a static VLAN).
[DeviceB] vlan 3
[DeviceB-vlan3] quit
