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

Hi Junxiao,

Yes, this is what I am doing from my example.

 93   // Install NLSR Controller on Node-1.
 94   NS_LOG_INFO ("Installing NLSR Controller application on all nodes");
 95   ndn::AppHelper nlsrcHelper ("ns3::ndn::NlsrcApp");
 96   nlsrcHelper.Install(nodes);

109   // Schedule the new prefis registration at 100 sec.
110   Simulator::Schedule(Seconds(100.0), advertise, nodes.Get(1));

I referred to the example given here:

I am explicitly selecting the node 1 to schedule this event on; but not
sure why it is returning -1 at runtime. Do you still think
is the correct way to go?
