Having wondered about the situation you explained, I tried to simulate a similar scenario. Produce node Pnode(responsible for /p prefix) is connected to other nodes than consumer node, directly. I tried with both default route(/) and GlobalRoutingHelper in place, separately. In both cases, forwarding strategy for all nodes was set to "multicast". But Pnode does not forward interests with /p in their name. For being sure, I've created another produce Onode responsible for /o prefix. My topology makes interest for prefix /o pass through Pnode. In Onode PIT I can see entries for /o. But no entry for /p is created because Onode does not receive interests for prefix /p form Pnode.<br>
Could you elaborate a bit more on the situation you're referring to?<span class=""><br>

Thanks,<br>

You got my view point. Can you please specify which file(s) I need to work<br>
out with.<br>
