ndnSIM

I am currently trying to implement a topology using AnnotatedTopologyReader in (ndnSIM 2.3), but when you want to implement using multicast forwarding strategy and bestroute, appdelay trace the same result, when I implementation topology with p2p exsmple: p2p.Install (nodes.Get ( 0), nodes.Get (1)); , Forwarding strategy can work, my question: does not support multicast topology in reader? whether there might be an error in the scenario that I created.

This is very important for me, I'm trying to implement a large topology that will be simulated, and it is impossible to use p2p, because each node using the coordinates. please give me advice ... thanks for all
