MSTP configuration
When you enable Multiple Spanning Tree Protocol (MSTP) on VLT nodes, configure both VLT peer nodes in the same MST
region to avoid network loops. Ensure that the VLAN-to-instance mappings, region name, and revision ID are the same on both
VLT peer nodes.
NOTE: OS10 supports a maximum of 64 MST instances.
To configure MSTP over VLT, follow these steps on both VLT peer nodes:
1. Enable MSTP.
CONFIGURATION mode
spanning-tree mode mst
2. Enter MST configuration mode.
CONFIGURATION mode
spanning tree mst configuration
3. Create an MST instance and add multiple VLANs as required.
