[ndnSIM] Setting up link metric

[Ahmed Sadek]

Hi Spyridon ,

Thank you for your reply. I still don't understand. If using the FibHelper
I set the *metric *between client 1-> Router 1 to be 100 and in the
topology file I set up the *metric *between client 1-> Router 1 to be 200,
so which one takes effect and why ?

Thanks!
Ahmed
