In one embodiment, a network device receives on a first port a first spanning tree protocol (STP) control message including a first path-tracking field corresponding to a given spanning tree instance in a network. The first path-tracking field includes a value based on one or more other network devices that have propagated the first STP control message. The network device receives on a second port a second STP control message including a second path-tracking field corresponding to the given spanning tree instance. The second path-tracking field includes a value based on one or more other network devices that have propagated the second STP control message. The network device utilizes the values from the first path-tracking field and the second path-tracking field to select a root port for the given spanning tree instance.
