Hi Nagu, Just a couple of follow up questions please. 1) Can you use the multicast feature with TIPC?
2) Can you point me to the documentation that explains how to configure dtm to use the multicast feature?

Alternatively, using the existing multicast feature of DTM, you can restrict discovery messages by adding those 10 nodes to a reserved multicast group(even though they are in same subnet), so that they will get discovered using multicast messaging.
