Really, the only way this could happen is if Router B is not announcing its routes to 172.16.16/24 and Router A has a default route to its Ethernet interface.

Is this what you're trying to do:
route-map <foo> match <whatever> set ip next-hop <something>
Not really, what I want is router A to learn that ther is no next hop IP- the subnet is on the local ethernet. -Ralph
