looks like no one has responded here, let me just throw in a few quick words:

regarding the issue of allowing an interest packet going in/out the same interface: yes, this has been a long recognized need from the earlier work on vehicle networking led by Prof. Giovanni Pau (you can find a few papers on this work if you just search his name on NDN publication list).

I recall this was discussed multiple times in NFD calls, though I lost track of the latest status on the implementations.  Alex and Junxiao?

Regarding another issue raised in your earlier msg (In a wireless mesh scenario, how does NFD populate the RIB): there are multiple solutions, depending on specific app scenarios, some may fit better than others
- the vehicle networking papers develop some solutions
- Beichuan's group has done work with name/prefix discovery, you probably can find some paper from NDN publications
- there is also ongoing implementation (no publication yet) using geo location based forwarding for rooftop mesh network

> In my current scenario, I pre-register the prefixes and faces using the "nfdc register" command (I'm using NFD 0.5.0). In the event of a new node joining the network, does it need to register the remote faces in order to start communicating? Is there a workaround/node discovery service in NFD?
