(page 3-164) with the same set of instances, and the same instance (on each
bridge) with the same set of VLANs. Also, note that RSTP treats each
MSTI region as a single node, connecting all regions to the Common
Spanning Tree.
To use multiple spanning trees:
1. Set the spanning tree type to MSTP (STA Configuration, page 3-161).
2. Enter the spanning tree priority for the selected MST instance (MSTP
VLAN Configuration).
3. Add the VLANs that will share this MSTI (MSTP VLAN
Configuration).
Note: All VLANs are automatically added to the IST (Instance 0).
To ensure that the MSTI maintains connectivity across the network, you
must configure a related set of bridges with the same MSTI settings.
