Description: The regional path cost of the Designated Port of the segment connected to this port. This value is compared to the Root Path Cost field in received bridge PDUs.
What is rldot1sMstpExtPortDesignatedRegionalCost?
This object records the path cost assigned to the designated port (root-facing port) of a spanning tree segment in Multiple Spanning Tree Protocol (MSTP). This cost is used by the protocol to calculate the best path to the root bridge; lower costs indicate faster or more preferred links. Network engineers examine this when tuning spanning tree topology or diagnosing why traffic takes an unexpected path through redundant bridges.
