You've had a few suggestions, here's mine.

From the picture, it looks like a large ogee moulding with the addition of a
strip of inside quarter round and then something similar to a 2"x3" backer
piece of wood for spacing. Inside quarter round is readily available as well
as router bits to cut it. So, all you really need to do is buy or create the
large ogee section. Should be relatively easy to route with a single
suitable bit, with several passes needed for each curve. I'd cut off a
section of the moulding and take to the store to match it up with suitable
router bits.
