GVRP is abbreviations of GARP VLAN Registration Protocol. It is a kind of application of GARP, based on GARP working mechanism to maintain VLAN dynamic register information in OLT and transfer it to other OLT. All OLTs that support GVRP can receive VLAN register information from other OLTs and dynamically upgrade local VLAN register information which includes: current VLAN members, and by which interface can reach VLAN members. And all OLTs supported GVRP can transfer local VLAN register information to other OLTs to make the consistency of the VLAN information of devices which support GVRP. VLAN register information transferred by GVRP includes static register information of local manual configuration and the dynamic register information of other OLT.

Enable GVRP

GVRP has two switches, one is under global configuration mode, and the other is under interface configuration mode. If you want to enable GVRP, these two switches should be in enable state.

By default, global GVRP and interface GVRP are disabled. It is important to note that, the GVRP can only be enabled on trunk port.

Configure the VLAN which Needs GVRP to Forward

The VLAN registration information transmitted by GVRP can be the local static VLAN or the VLAN learned via GVRP protocol. Moreover, this vlan can be transmitted via GVRP only after the administrator specified.

GVRP Configuration Example

1、Network requirements

Configuration example of GVRP service

As shown in the figure, OLT 1 and OLT 3 forward their static VLAN information to OLT 2 via GVRP protocol packet. OLT 2 transmits itself static VLAN and the VLAN that it learns via GVRP. At last, the VLAN information in OLT 1, OLT 2 and OLT 3 can be synchronized.

2、Configuration Roadmap:

1). Enable OLT 1 GVRP, and then distribute VLAN information announcement 2). Enable OLT 2 GVRP, and then distribute VLAN information announcement 3). Enable OLT 3 GVRP, and then distribute VLAN information announcement

After finishing the configuration, you can use the command of “show vlan” to check the VLAN registration information learned via GVRP.

Check the vlan information on OLT 1, you can find that the vlan 5-8 is learned via GVRP. OptiWay (config)#show vlan
