Comment 1 Martin Baulig 2012-06-27 00:21:15 UTC
Created attachment 2121 [details]
setsockopt() test
Comment 2 Martin Baulig 2012-06-27 00:23:13 UTC
In the attached testcase, the setsockopt() call fails when

	mreq.ipv6mr_interface = 0;

It works when using an actual interface id.  However, 0 is a valid number according to the manpage.
Comment 3 Martin Baulig 2012-06-27 00:42:00 UTC
See also #5496 and #5497.
Comment 4 Martin Baulig 2012-06-27 01:21:32 UTC
Testing on Linux and Windows shows that they only join the multicast group on one NIC (which actually seems to be a random one on Windows) when using interface id 0.

To test:

	IPAddress mcast_addr = IPAddress.Parse ("ff02::888");

	using (UdpClient client = new UdpClient (new IPEndPoint (IPAddress.IPv6Any, 9999))) {
		client.JoinMulticastGroup (mcast_addr);
		IPEndPoint ep = null;
		client.Receive (ref ep);

Then do 'netsh interface ipv6 show joins' on Windows and 'netstat -nag' on Linux.

This means that I could actually fix that quite easily in the runtime using that code from commit 504e2341 using if_nametoindex() on the interface that belongs to the machine's ip address.
