What is jnxMIMstMstiPortDesignatedRoot?

This object contains the Bridge Identifier of the bridge that serves as the regional root for a specific Multiple Spanning Tree Instance (MSTI) port, as recorded in outgoing BPDU configuration messages. It identifies the topology root that the port is using for its spanning tree calculations. Network administrators examine this to verify correct spanning tree root election and to diagnose MSTI topology problems on multi-instance bridges.
