It's seem may problem about redistribution between eigrp et ospf comes from
the way as network statement is used under ospf.
On a single router :
interface Serial0
ip address 1.1.1.1 255.255.255.0
interface Serial1
ip address 2.2.2.2 255.255.255.0
router eigrp 1
redistribute ospf 1 metric 1544 100 255 1 1500
network 2.0.0.0
router ospf 1
redistribute eigrp 1 subnets
network 1.1.1.0 0.0.0.255 area 0
network 3.3.3.0 0.0.0.255 area 0
1> With
router ospf 1
redistribute eigrp 1 subnets
