Hi,
I'm catching up on FreeBSD email after a long hiatus.

That's because the ip_multicast_if() hack has been deprecated in
-CURRENT for months now, because routed (and other multicast
applications) really should be using the RFC 3678 APIs.
I'm pretty sure I already pointed people at patches for converting
routed to use the updated multicast APIs much earlier in the year;
please check the archives, or see here:
http://people.freebsd.org/~bms/dump/routed.rfc3678.diff
I haven't tested or committed the routed patch due to a lack of user
feedback, sadly -- which is regrettable, we all end up feeling the pain
during a release cycle if issues aren't nipped in the bud there and then.
Marko: I would much prefer it if ip_multicast_if() is not reintroduced
to 7-CURRENT.
kind regards,
BMS
