In a network containing devices with both GVRP and MSTP enabled, GVRP packets are forwarded
along the CIST. If you want to advertise packets of a specific VLAN through GVRP, be sure to map the
VLAN to the CIST when configuring the MSTP VLAN mapping table (the CIST of a network is spanning
tree instance 0).
The role (root, branch, or leaf) of each device in each spanning tree instance is determined.
