Figure 15-5 Typical GVRP Application Topology
To enable dynamic VLAN information register and update among switches, GVRP protocol is to be configured
in the switch. Configure GVRP in Switch A, B and C, enable Switch B to learn VLAN100 dynamically so that
two workstations connected to VLAN100 in Switch A and C can communicate with each other through Switch
B without static VLAN100 entries.
Configuration Item
Configuration description
VLAN100
Port 2 -6 of Switch A and C.
Trunk port
Port 11 of Switch A and C, Port 10, 11 of Switch B.
Global GVRP
Switch A, B, C.
Port GVRP
Port 11 of Switch A and C, Port 10, 11 of Switch B.
Connect the two workstation to the VLAN100 ports in switch A and B, connect port 11 of Switch A to port 10 of
Switch B, and port 11 of Switch B to port 11 of Switch C.
The configuration steps are listed below:
Switch A:
Switch(config)# gvrp
Switch(config)#vlan 100
Switch(Config-Vlan100)#switchport interface ethernet 1/0/2-6
Switch(Config-Vlan100)#exit
Switch(config)#interface ethernet 1/0/11
Switch(Config-If-Ethernet1/0/11)#switchport mode trunk
Switch(Config-If-Ethernet1/0/11)# gvrp
Switch(Config-If-Ethernet1/0/11)#exit
Switch B:
Switch(config)#gvrp
Switch(config)#interface ethernet 1/0/10
Switch(Config-If-Ethernet1/0/10)#switchport mode trunk
Switch(Config-If-Ethernet1/0/10)# gvrp
Switch(Config-If-Ethernet1/0/10)#exit
Switch(config)#interface ethernet 1/0/11
Switch(Config-If-Ethernet1/0/11)#switchport mode trunk
Switch(Config-If-Ethernet1/0/11)# gvrp
Switch(Config-If-Ethernet1/0/11)#exit
Switch C:
Switch(config)# gvrp
Switch(config)#vlan 100
Switch(Config-Vlan100)#switchport interface ethernet 1/0/2-6
Switch(Config-Vlan100)#exit
