Leaf Node
Configuration
Table 189 lists MSTP-related configurations about leaf nodes.
n
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.)
Prerequisites The status of the switches in the spanning trees is determined. That is, the status
(root, branch, or leaf) of each switch in each spanning tree instance is determined.
