The wireshark plugin does not know how to handle NDN packets that are not encapsulated into TCP or UDP.
There are a couple of things you can do:
1/ (ideal) update wireshark plugin so it knows that PPP protocol 0x0077 means NDN packets and process them exactly as UDP packet payload
2/ use ndndump (https://github.com/cawka/ndndump)
3/ use UDP tunnels in ndnSIM. It is way harder to set up the simulation this way, but not impossible. You can basically combine ndn-simple-with-pcap.cc and ndn-simple-udp.cc scenarios.
