EIGRP Multile Paths Advertisement

Hi GS:

Maybe I'm missing something. I have two routers connected to each other
with both a serial and ethernet connection. A route is redistributed into
EIGRP on one router. Shouldn't I see it when I do a "show ip route x.x.x.x"
as being advertised over both links? It is preferring the ethernet
interface, but if I shut the ethernet interface, than I see it advertised
over the serial link - so I don' think it is a FD/AD issue. Any help would
be greatly appreciated.
