Ok. I think I see how this works. Because R3 and R5 only send an RP message
for 224.0.0.0/4 the mapping agent will not split this up. You have to break
up the groups on the autorp-candidates.
In other words If I do this on R3:
access-list 3 permit 237.0.0.0 0.255.255.255
access-list 3 permit 238.0.0.0 0.255.255.255
access-list 3 permit 239.0.0.0 0.255.255.255
ip pim send-rp-announce lo 0 scope 5 group-list 3
Now R1 can filter the other groups except 239.0.0.0/8. Otherwise It just
filters the only group it sees.
