are R5, R2, and R1 in a hub and spoke topology? ...does R1 already
know of the routes that R2 will be redistributing into OSPF? If it
already knows of the routes and considers them "internal", you
shouldn't have to do anything since EIGRP internal routes have a lower
admin' distance than external routes learned via another protocol.
if R1 somehow has other EIGRP external (admin distance 170) knowledge
of the routes R2 is advertising just set your OSPF external distance
to 171 or greater so that they won't be preferred.
