<div class="">if your topology is simple as you said (2 nodes), you can directly send packets from one node to the other.</div>

<div class="">NFD should have created ethernet faces and you use the nfdc command to establish a new route through the ethernet face directly (i.e., run NDN over L2). You do not need a routing protocol for such a simple scenario.</div>
