Now I feel I got a better understanding of your question (or where the confusion came in)

when talking about an NDN network, one needs to look at the world from NDN viewpoint: NDN is the network layer.
When TCP/UDP/IP tunnels are used to interconnect NDN nodes, they play the same role as physical links, as far as NDN is concerned.
