  Note: 
In a network that contains switches with both GVRP and MSTP employed, GVRP 
packets are forwarded along the CIST. If you want to broadcast 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 the spanning tree instance 
numbered 0.) 
 
1.2.1  Prerequisites 
The status of the switches in the spanning trees are determined. That is, the status 
(root, branch, or leaf) of each switch in each spanning tree instance is determined.
