By default GVRP ports are in normal registration mode. If the device on the other side is not capable of sending GVRP messages, or if you do not want to allow the switch to prune any of the VLANs, use the fixed mode. Fixed mode ports will forward for all VLANs that exist in the switch database. Ports in forbidden mode forward only for VLAN 1. Dynamic VLAN creation is configured on a switch-by-switch basis.
GVRP does not synchronize between switches, but only adds VLANs on devices that have dynamic creation enabled in order to pass traffic between trunks. To enable dynamic VLAN creation, all the trunk ports on the switch have to be If the switch has any non VLANs will be added only for join messages received across a normal registration port.

When a network is complex and the network administrator is unfamiliar with the network topology, or when many VLANs are configured on the network, the manual configuration workload is enormous.
In addition, configuration errors may occur due to human error. GVRP can be configured on the network to implement automatic registration of VLANs, reducing configuration workload and the likelihood of configuration errors.
