If Mcast99 has a direct peering with fmbone, it will accept the SA
messages because SA's are always accepted from the RP itself. It
will also accept the messages from NL because of the MBGP route.
That only accounts for 2 copies, though, we haven't figured out yet
where the 1000 others came from =)
Do you have any mesh-groups configured?
If you do a unicast traceroute to 195.83.118.16, do you get there or
is there a routing loop? A unicast loop would explain everything.
