If you want to broadcast packets of a specific VLAN through GVRP, besure 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 Before configuration, determine what roles the switches will play in the spanningtrees, that is, whether a switch will be the root, a branch, or a leaf in a spanning treeConfiguring an MSTRegionRefer to “Configuring an MST Region”.Table 159 Leaf node configurationOperation Description Related sectionEnable MSTP RequiredNormally, to reduce networktopology jitters caused byconfiguration, you arerecommended to enableMSTP after completing otherrelated configurations.Enabling MSTPConfigure an MST region Required Configuring an MST RegionConfigure MSTP operation mode Optional Configuring MSTP OperationModeConfigure the timeout time factor Optional Configuring the Timeout TimeFactorConfigure the maximumtransmission speed of a portOptionalThe default is recommended.Configuring the MaximumTransmission Speed of a PortSet a port as an edge port Optional Setting a Port as an Edge PortConfigure the path cost of a port Optional Configuring the Path Cost ofa PortConfigure the priority of a port Optional Configuring the Priority of aPortConfigure a port to connect topoint-to-point linkOptional Configuring a Port to Connectto Point-to-Point Link
