Giuliano,

remember that loopback interface is a "logical" interface, thus, it will not
know where to send traffic to...therefore it will look at physical intercaes
directly attached to the same router to send to.

correct me if I am wrong.

OK, but I did not understand the meaning of that interface !!!
 

 
When I create one and put a IP number on it, it start to scan all phisical
interfaces to send packages ?
