In a previous append, I pointed out that there is still an
open issue with a sender being outside of the PIM domain that
allocated the address.
Just an idea. What about sending a PIM register from the sender's RP
to the RP that belongs to the multicast address? It would need another
protocol change, of course.
It can lead to a DoS attack on the embedded address. A bad guy could
embed any address in the multicast address that it wants to attack.
So using register messages would require some type of authentication
