transmits VLAN attributes to the whole layer 2 network through GARP protocol.
a typical application scene
A and G switches are not directly connected in layer 2 network; BCDEF are intermediate
switches connecting A and G. Switch A and G configure VLAN100-1000 manually while
BCDEF switches do not. When GVRP is not enabled, A and G cannot communicate with each
other, because intermediate switches without relevant VLANs. However, after GVRP is
enabled on all switches, its VLAN attribute transmission mechanism enables the intermediate
switches registering the VLANs dynamically, and the VLAN in VLAN100-1000 of A and G can
communicate with each other. The VLANs dynamically registered by intermediate switches will
be deregistered when deregistering VLAN100-1000 of A and G switches manually. So the
same VLAN of two unadjacent switches can communicate mutually through GVRP protocol
instead of configuring each intermediate switch manually for achieving the purpose of
simplifying VLAN configuration.
