Please use appropriate mask when defining the multicast group on router 1
and 4, seems like the mapping agent thinks that you are trying to advertise
the same multicast(group,rp) mapping from two different sources and it is
choosing the one with the highest ip address.
I see you have google account, we can take this offline if you want, just
ping me in Google IM.
