| You haven't provided the information that router B would use

Brian Haberman provided an entirely good enough answer (which also was
that there wasn't enough information, but with different missing info).
| Is router B configured so that the subnet-local zone IDs of its
| A-B and C-D interfaces are the same or different?
What subnet local zone id ?
I wasn't aware that such a thing existed?
If it did, it would have to be assigned, which would make subnet-local
multicast jump out of the category of "no special config required"
that is (I think rightly) claimed for it, wouldn't it?
| The unicast addresses uses on those links are immaterial to the
| decision of whether or not to forward subnet-local packets between
| these two links.
Hmm ... that is exactly the opposite of what Brian said, and is also
contrary to what (little) I know about multicast forwarding. Generally
that's done based upon the (unicast) source address of the packet (along
with the destination address, naturally).
