<p class="MsoNormal">Hi,<o:p></o:p></p>

<p class="MsoNormal">I have a topology of five wireless nodes all running NFD v.0.5. on Ubuntu 16.04. I am using Ethernet as the transport method with one multicast group, as follows
<i>face_system.ether. </i><i>mcast_group 01:00:5E:00:17:AA</i>.<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">I am using “<i>nfdc register /ndn/broadcast ether://[01:00:5E:00:17:AA]</i>” to register nodes to the multicast group, which creates the following faces:<o:p></o:p></p>

<p class="MsoNormal">When I test connectivity using NDN-Ping it works between one hop neighbors, but not over multiple hops. I assume that is because the architecture prevents it from sending Int/Data packets over the same face it received, in order to prevent
loops. Am I right?<o:p></o:p></p>
<p class="MsoNormal">If so, what is the best way to address this issue?<o:p></o:p></p>

<p class="MsoNormal">PS: my issue is a bit different from this (<a href="http://www.lists.cs.ucla.edu/pipermail/nfd-dev/2015-April/001018.html">http://www.lists.cs.ucla.edu/pipermail/nfd-dev/2015-April/001018.html</a>) because I have only one Ethernet interface.<o:p></o:p></p>
