<p>Just wanted to mention, even with using IP static routes might not work as there is no routing protocol on IP level (However, each node should be able to reach its neighbor using IP and the correct interface and there should be no problem in registering
routes towards neighbor in NFD). </p>
<p><br>
</p>
<p>One needs to first install routes for IP (using the route command) and then install routes for NFD.</p>

If you would like to log forwarder information on a node, you can add an additional parameter to its definition in the topology configuration file:
<div class=""><br class="">
</div>
<div class=""><font face="Menlo" class="">[nodes]<br class="">
a: _ nfd-log-level=DEBUG</font></div>
<div class=""><font face="Menlo" class="">...</font></div>
<div class=""><font face="Menlo" class=""><br class="">
</font></div>
<div class="">The log will be written to the node’s home folder (by default, /tmp/$NODE_NAME).<br class="">

<div class="">In the current version of Mini-NDN, using the IP address is the standard way to achieve static routes. In the future, we would like to provide a static routing helper that would allow a user to call something like:</div>

<div class="">Hi dear MiniNdn team<br class="">
<br class="">
I am interested in using MiniNdn for an initial basic experiment between three nodes: a consumer , a forwarder and a producer. It is highly possible that I am missing something, but the consumer is not receiving the data from the producer.

Could I ask for some advice of how this could be achieved by using MiniNdn? <br class="">
