I am completely innocent of rfc1812, and have been out of the game for a
long time, but I am pretty sure I was taught (and in turn taught) that a
router would reply using the address of the interface that originated
the reply unless that interface was unnumbered, in which case it would
reply from the loop-back address.
Never too old to learn something.
