Chuck,
Try the summery-address command under ospf calling the summery that you want
advertised in eigrp. In ospf, you must create the summery and it should
automaticly filter the more specific routes. It works just like the
"area-range" command only "summery-address" is used between routing domains
and "area-range" is for summeries between ospf areas.
If the networks specified in the summary-address are external to the
OSPF domain, it will summarize them when redistributing INTO OSPF.
If the networks specified in the summary-address are internal to the
OSPF domain, it will summarize them when redistibuting FROM OSPF into
another routing protocol.
Hope this helps
Tony Medeiros
