If both GVRP and MSTP are enabled on a device at the same time, GVRP packets
will be forwarded along the CIST. Therefore, if both GVRP and MSTP are running
on the same device and you wish to advertise a certain VLAN within the network
through GVRP, make sure that this VLAN is mapped to the CIST (instance 0) when
configuring the VLAN-to-instance mapping table. For detailed information of
GVRP, refer to
“GVRP Configuration” on page 139.
