[ndnSIM] FIB Manual Configuration

[Alex Afanasyev]

Hi Cesar,

Did you specify  "helper.SetDefaultRoutes(true);" ?  If so, you are getting a "default" route installed on each node, pointing to all available faces.

In the visualizer, you can check content of FIB on each node.

PS
For the list of default choice of strategies, check model/ndn-l3-protocol.cc (lines 108-111):
          /               /localhost/nfd/strategy/best-route
          /localhost      /localhost/nfd/strategy/broadcast
          /localhost/nfd  /localhost/nfd/strategy/best-route
          /ndn/broadcast  /localhost/nfd/strategy/broadcast

All of these strategies require some FIB entry to be present, so you definitely has some FIB entry installed by some process.
