Spanning Tree Algorithm Configuration 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.
