[ndnSIM] multicast-udp-face

[Carl]

Hi folks,

is there any example for using multicast-udp-face ?. could it be used 
for broadcasting an interest to neighbors ?.

Moreover, what is the first argument in the constructor ? (const 
protocol::endpoint &multicastGroup). How this could be initialized so 
that a node can broadcast an interest to the neighbors ?

If we use such a multicast face, then what about the strategy ?. I mean 
why not to perform multicast using the multicast strategy for example ?. 
And after all, in general, what is the true way of broadcasting an 
interest to neighbors

Alex, could you please shed light on this ?

Thanks,
C
