[ndnSIM] Question about updating name prefix list of the routers

[Mahsa Aghajani]

Dear ndnSIM users

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?
If so, how can I use these functions in ndnSIM-NLSR? I have written this
code in
ndn-nlsr-exec.cpp file, but I got some errors relating to sending interest
from face :

void
Nlsr::withdraw()
{
  m_nlsr.getPrefixUpdateProcessor().updateProcessor.enable();

  ndn::nfd::ControlParameters parameters;
  parameters.setName("/prefix/to/advertise/");

  ndn::Name withdrawCommand("/localhost/nlsr/prefix-update/withdraw");
  withdrawCommand.append(parameters.wireEncode());

  shared_ptr<Interest> withdrawInterest =
make_shared<Interest>(withdrawCommand);
  keyChain.signByIdentity(*withdrawInterest, opIdentity);

  face->receive(*withdrawInterest);
  face->processEvents(ndn::time::milliseconds(1));
}

Thanks and regards.
