Spanning Tree Algorithm Configuration
3-133
3
To use multiple spanning trees:
1. Set the spanning tree type to MSTP (STA Configuration, page 3-123).
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.
