2511553-KDU 137 365 Uen D 2006-06-16
To use multiple spanning trees:
1. Set the spanning tree type to MSTP (STA Configuration, page 238).
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, configure a
related set of bridges with the same MSTI settings.
