GVRP Configuration on Cisco

In this configuration example, we will focus on how to configure GVRP on Cisco. Here, for our GVRP Configuration Example, we will use the below topology. Let’s start our GVRP Configuration on each of these Switches.

Switch A Confguration

Firstly, we will create our VLANs (40 and 50) then we will enable GVRP globally on the switch.

Cisco-Switch-A> enable
Cisco-Switch-A# configure terminal
Cisco-Switch-A(config)# vlan 40
Cisco-Switch-A(config)# vlan 50
Cisco-Switch-A(config)# gvrp enable

Then we will configure the interfaces and we will also enable GVRP on these interfaces.We will configure the vlan ports as Access and the trasport port (the link between the switches) as Trunk.We will allow only the required VLAN on Access ports, but we will allow all VLANs on Trunk port.

Cisco-Switch-A(config)# interface fastethernet 1/4
Cisco-Switch-A(config-if)# switchport mode access
Cisco-Switch-A(config-if)# switchport access vlan 40
Cisco-Switch-A(config-if)# gvrp enable

Cisco-Switch-A(config-if)# interface fastethernet 1/5
Cisco-Switch-A(config-if)# switchport mode access
Cisco-Switch-A(config-if)# switchport access vlan 50
Cisco-Switch-A(config-if)# gvrp enable

Cisco-Switch-A(config-if)# interface fastethernet 1/1
Cisco-Switch-A(config-if)# switchport mode trunk
Cisco-Switch-A(config-if)# switchport access vlan all
Cisco-Switch-A(config-if)# gvrp enable
Cisco-Switch-A(config-if)# end

Lastly, we will save our configuration.

Cisco-Switch-A# copy running-config startup-config

Switch B Configuration

We will configure Switch B similar to switch A.

Cisco-Switch-B> enable
Cisco-Switch-B# configure terminal
Cisco-Switch-B(config)# vlan 40
Cisco-Switch-B(config)# vlan 50
Cisco-Switch-B(config)# gvrp enable
