Note that if a static VLAN is configured on at least one port of a switch, and
that port has established a link with another device, then all other ports of that
switch will send advertisements for that VLAN.
For example, in the following figure, Tagged VLAN ports on switch "A" and
switch "C" advertise VLANs 22 and 33 to ports on other GVRP-enabled
switches that can dynamically join the VLANs.

A port can learn of a dynamic VLAN through devices that are not aware of
GVRP (Switch "B", above). VLANs must be disabled in GVRP-unaware devices
to allow tagged packets to pass through.
A GVRP-aware port receiving advertisements has these options:
If there is not already a static VLAN with the advertised VID on the
receiving port, then dynamically create the VLAN and become a member.
Switch "C"
Switch "C":
GVRP On
Port 5 dynamically joins VLAN 22.
Ports 11 and 12 belong to Tagged VLAN 33.
