Hello,

I think you can find the answers to your questions in the NFD Developer

No, the consumer does not flood the first Interest but sends it on the 
shortest path (= lowest cost face).

You can set the link metric in your simulation file (search for "metric" 
here http://ndnsim.net/current/examples.html), and the default will be 1.

Yes, if you didn't set any other link metrics.
