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

[Junxiao Shi]

Hi Sabet

This log confirms NLSR has received the Interest. However, the Interest is
malformed: it should be a Command Interest which has four more components,
but they are missing because you forgot to sign the Interest via KeyChain.

Also, next time you report a crash (including "terminate called ..."), be
sure to include a stack trace. See
http://www.lists.cs.ucla.edu/pipermail/nfd-dev/2016-May/001748.html

Yours, Junxiao

Ashlesh,

I have installed a simple app on one router node just for expressing the
advertise command interest as follows:

    auto advertiseCommand = make_shared<Interest>();
    Name command = Name("/localhost/nlsr/prefix-update/advertise");
    ndn::nfd::ControlParameters parameters;
    parameters.setName(Name("updated-prefix"));
    advertiseCommand->setName(command.append(parameters.wireEncode()));
    m_transmittedInterests(advertiseCommand,this,m_face);
    m_appLink->onReceiveInterest(*advertiseCommand);

The last 2 lines are for ndnSIM applications. They basically send packet on
wire.

For this I have:

6s 2 nfd.Forwarder:onIncomingInterest(): [DEBUG] onIncomingInterest
> face=261 interest=/localhost/nlsr/prefix-update/advertise/h%12%07%10%
> 08%0Eupdated-prefix

But just after that:

And it seems it has nothing to do with encoding. I have tried without
encoding, but the error is the same. Also tried with ndn::name instead of
controlparameters, but again the same error comes up.
There is no other application on node 2 but nlsr;

I appreciate your help.

Thanks,
Sabet
