Enter the following commands on edge device B.
device> enable
device#configure terminal
device(config)#vlan 20
device(config-vlan-20)#untag ethernet 2/24
device(config-vlan-20)#tag ethernet 4/1
device(config-vlan-20)#vlan 30
device(config-vlan-30)#untag ethernet 4/24
device(config-vlan-30)#tag ethernet 4/1
device(config-vlan-30)#exit
device(config)#gvrp-enable
device(config-gvrp)#enable ethernet 4/1
device(config-gvrp)#block-learning ethernet 4/1
Enter the following commands on edge device C.
device> enable
device#configure terminal
device(config)#vlan 30
device(config-vlan-30)#untag ethernet 2/24
device(config-vlan-30)#tag ethernet 4/1
device(config-vlan-20)#vlan 40
device(config-vlan-40)#untag ethernet 4/24
device(config-vlan-40)#tag ethernet 4/1
device(config-vlan-40)#exit
device(config)#gvrp-enable
device(config-gvrp)#enable ethernet 4/1
device(config-gvrp)#block-learning ethernet 4/1
Dynamic core and dynamic edge
In this configuration, the core and edge devices have no statically configured VLANs and are enabled
to learn and advertise VLANs. The edge and core devices learn the VLANs configured on the devices
in the edge clouds. To enable GVRP on all the ports, enter the following command on each edge
device and on the core device.
device> enable
device#configure terminal
device(config)#gvrp-enable
device(config-gvrp)#enable all
Fixed core and dynamic edge
In this configuration, GVRP learning is enabled on the edge devices. The VLANs on the core device
are statically configured, and the core device is enabled to advertise its VLANs but not to learn VLANs.
The edge devices learn the VLANs from the core.
Enter the following commands on the core device.
device> enable
device#configure terminal
device(config)#vlan 20
device(config-vlan-20)#tag ethernet 1/24
device(config-vlan-20)#tag ethernet 6/24
device(config-vlan-20)#vlan 30
device(config-vlan-30)#tag ethernet 6/24
device(config-vlan-30)#tag ethernet 8/17
device(config-vlan-30)#vlan 40
device(config-vlan-40)#tag ethernet 1/5
device(config-vlan-40)#tag ethernet 8/17
device(config-vlan-40)#vlan 50
device(config-vlan-50)#untag ethernet 6/1
device(config-vlan-50)#tag ethernet 1/11
device(config-vlan-50)#exit
device(config)#gvrp-enable
