Hi,

I'm currently experimenting dbeacon to test my multicast ipv6
connectivity. For about 5 minutes dbeacon work correctly (building a
nice matrix) and then the machine sends a "block old sources" which
block all beacons to reach the machine.

the netstat -g command shows that the interface is still subscribed to
the multicast group.

Is this the expected behavior or is it a bug somewhere?

Running debian lenny with 2.6.26-1-amd64 kernel.

Best regards

Laurent Bigonville
