Unless they have been heavily patched, I would expect vic and rat to be emitting RTCP traffic as they normally do. As this traffic gets placed on the local LAN, it will be spotted by the designated router which will then (assuming PIM-SM is being used) report to the Rendezvous Point that the vic/rat machine is a new "active source" for the group being used for the RTCP traffic reports. The port number for the RTCP traffic "should" be an odd number, one higher than the even number being used for the RTP transported media traffic. Thus, it is my belief, that as the vic/rat receiver is thus a "source" of RTCP traffic it will effect trees built to others. They will be receiving the RTCP traffic (from other vic/rat etc) as well as RTP transported media from the audio/video sources and thus their designated routers will building first a shared tree to the RP, but as RTPC traffic arrives, shortest path trees back to the other vic/rat machines that are emitting RTCP.
