Explanation
Create a new region policy under the spanning tree policy. Map VLAN range to MST instance number. Bind the spanning tree policy to the switch policy group. These steps allow the ACI system to understand MST BPDUs. ACI can now flush the appropriate endpoints when a TCN message is received in an MST domain.
