-i interface
Specify the interface name to use sending packets. By de-
fault, kernel will decide.
-s scope Specify the hint in order to decision of source IP address to
send packets. By default, global scope is applied. If you
don't specify interface, mcastsend ignores this option.
scope takes one of the following numeric:

2 link local
5 site local
14 global
