I have no coredumps, sorry. Xorp stops working in the middle of
operation (after some configuration changes, but not directly after
that).

How? I am not experienced here, sorry.

Here might be the problem. I was told sending data outside the
university, perhaps including this encapsulated format, is bad and makes
problems. I was told something about wrong routes with multicast and so
on. So a local solution would be fine :)

There was, but no data has been received.

Okay, I will try that (tomorrow, 2am here).

Right.

The sender was running, but I don't have (S,G). I will recheck.
