In my simple simulation with NDN, I just want to test the CS, FIB, PIT. But after I set all these attributes using SetConternStore(), SetForwardingStrategy(), SetPit(), they didn't make sense. Every time the consumer sent a request, it will go to the producer, and then return a response. I think there must be something wrong, but still I find it out. Would you please help me?
