This sounds similar to a problem we experienced recently 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.
Do you have a multicast beacon set up
(http://dast.nlanr.net/Projects/Beacon/
<BLOCKED::http://dast.nlanr.net/Projects/Beacon/> )? 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 ;-)
Good Luck!
Mike
