due to a bug in a Juniper router's PIM implementation. The router would
delay the S, G JoinPrune messages so the upstream neighbor would tear down the
shortest path tree, disconnecting the session. When the JoinPrune messages
did finally appear, things got rebuilt and the session was joined again with
working audio & video.</FONT></SPAN></DIV>

Someone who knows multicast should be able to monitor the beacon data and
troubleshoot your multicast problem. I was quoting from trouble tickets so
I only sound like I know what I'm talking abbot ;-)</FONT></SPAN></DIV>
