I have about 1 GB of logs with varies tries and configurations. You can
have them, but I did not document what exactly was configured. Perhaps
you can find the lines that tell you this information.
I will give you the addresses via E-Mail.
The new logfile has been initialized just now. I will put a recent
version online from time to time.

What exactly does inside mean here? One interface is directly connected
to a router/switch that does IGMP and PIM-SM. The university explicitely
activated the mcast feature for our port. I can see various multicast
messages even without any Xorp running. That named router appears in my
neighbors section.

At the moment the announcements from the internal network do not appear
in the external network. Manually starting the stream does not work, I
will analyze the packet flow later.
Thanks again for your help!
