Configuring Multiple Spanning Trees

1. Set the spanning tree type to MSTP (page 209).
2. Enter the spanning tree priority for the selected MST instance on the
Spanning Tree > MSTP (Configure Global - Add) page.
3. Add the VLANs that will share this MSTI on the Spanning Tree > MSTP
(Configure Global - Add Member) page.

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.
