Were you seeing exactly same error messages: "send_from_multicast_if
failed: Network is unreachable" ?

The origin of the issue is the FreeBSD kernel, but I don't know
whether the behavior has been changed in FreeBSD-current.
Bruce, do you have any info on the subject?

The simplest work-around is to add 224.0.0.0/4 route to the kernel.
It doesn't matter which particular next-hop address you will
choose. E.g.:

route add 224.0.0.0/4 10.10.10.10

Alternatively, a default static route will also make the issue go
away.
