 Note:
In a network that contains switches with both GARP VLAN registration protocol (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
MSTI numbered 0.)
1.2.1 Configuration 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 MSTI is determined.
