I don't know about a new knob, but it's the same notion
as rp_filter, so why not use rpf for RTN_LOCAL types?
Ie, allow RTN_LOCAL and RTN_UNICAST at the top, but
check rpf if the devs aren't equal or RTN_LOCAL
It seems like not a good thing to rely on in the first place, though;

If so, it may do what you want just by setting that

IPv6 on Linux uses a per-interface addressing model as opposed
to the per-host model used by IPv4.

I may have switched the ordering in the last test I ran,
but I always join the group on the interface different
from the one I send on.

You're joining the group on interface eth1, which is the
sender, right? You need to be a member on eth0 to receive it
there. I think your program needs another argument, to
specify the receiving interface, which you want to be
different from the sending interface.

Can you send the contents of /proc/net/igmp and the packet trace,
also? And the code?

Here is the info off the reproducing system:

I'm not clear on your configuration.
Are the sender and receiver running on the same machine? Are
you saying eth0 and eth1 are connected on the same link?

We've been trying to field some questions regarding multicast
behavior and one such behavior has stumped us.
I've reproduced the following behavior on 2.6.23.
The application opens 2 sockets. One socket is the receiver
and it simply binds to 0.0.0.0:2000 and joins a multicast group
