MSTP (802.1s) ensures that only one active path exists between any two nodes in a spanning-tree instance. A spanning-tree instance comprises a unique set of VLANs. MSTP instances significantly improve network resource utilization while maintaining a loop-free environment.
Enable MSTP (default mode for spanning-tree):
spanning-tree mode mst
name my-mstp-region
