<p>So this m_face, is it the same face that is passed to NLSR?</p>
<p>That may be a problem. Since you are sending the interest out of that face and NLSR is listening for request on the same face, NFD would not forward the interest back to the same face. Hence interest reject message from NFD.</p>

<p>You would use expressInterest to send an advertise/withdraw request.</p>
<p>(<a href="https://github.com/named-data/NLSR/blob/master/tools/nlsrc.cpp#L158" class="m_-4336618176295913307gmail-m_1350591666439780934OWAAutoLink" id="m_-4336618176295913307gmail-m_1350591666439780934LPlnk198243" target="_blank">https://github.com/named-data<wbr>/NLSR/blob/master/tools/nlsrc.<wbr>cpp#L158</a>)</p>
<p><br>
</p>
The advertise/withdraw commands are only accepted on localhost (<a href="https://redmine.named-data.net/projects/nlsr/wiki/NLSR_Management" class="m_-4336618176295913307gmail-m_1350591666439780934OWAAutoLink" id="m_-4336618176295913307gmail-m_1350591666439780934LPlnk413863" target="_blank">https://redmine.named-data.ne<wbr>t/projects/nlsr/wiki/NLSR_Mana<wbr>gement</a>).<br>
<div><br>
</div>
<div>For example, nlsrc issues an advertise interest to NFD, which gives it to NLSR (since NLSR is listening for it).</div>
<div>Then NLSR can respond appropriately.</div>

<p>face->receive is for the unit tests (written for testing purpose). Remove it.</p>
<p>After that call whatever the equivalent of face->processEvents is in ndnSIM (<span style="font-family:calibri,arial,helvetica,sans-serif,"apple color emoji","segoe ui emoji",notocoloremoji,"segoe ui symbol","android emoji",emojisymbols;font-size:16px">I
am not familiar with ndnSIM</span>).</p>
<p><br>
</p>
<p>Also look at nlsrc tools - which is a real application to send advertise/withdraw command and would be closer to what you want than the test (however, one thing missing in nlsrc is that it will sign the interest with default identity - so you have to make
sure that default identity is set to operator to do the advertise/withdraw request This should not matter if security is turned off in nlsr.conf file - iirc ndnSIM-NLSR has it turned off).</p>
<p>(<a href="https://github.com/named-data/NLSR/tree/master/tools" class="m_-4336618176295913307gmail-m_1350591666439780934m_3560829579670701776OWAAutoLink" id="m_-4336618176295913307gmail-m_1350591666439780934m_3560829579670701776LPlnk208479" target="_blank">https://github.com/named-data<wbr>/NLSR/tree/master/tools</a>)</p>
<p>But yes, to advertise/withdraw prefix this is the functionality you would use.</p>

</div>
<div>I want to update name prefix lists of routers during a simulation including adding/removing some name prefixes to/from a router. Should I use advertise or withdraw functions of NLSR for doing this?</div>
<div>If so, how can I use these functions in ndnSIM-NLSR? I have written this code in </div>
<div>ndn-nlsr-exec.cpp file, but I got some errors relating to sending interest from face :</div>
