Configuring Multiple Spanning Trees
MSTP generates a unique spanning tree for each instance. This provides
multiple pathways across the network, thereby balancing the traffic load,
preventing wide-scale disruption when a bridge node in a single instance
fails, and allowing for faster convergence of a new topology for the failed
instance.
By default all VLANs are assigned to the Internal Spanning Tree (MST
Instance 0) that connects all bridges and LANs within the MST region.
This switch supports up to 65 instances. You should try to group VLANs
which cover the same general area of your network. However, remember
that you must configure all bridges within the same MSTI Region
