(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 3-144).
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.
