Hi,
i think Mohan is not running 2 ospf process. if you are running 2 ospf
process, of course , during redistribution, distribution-list will filter
the route since routes are injected into the opsf but not the link-states. I
think the solution is to configure area 1 as stub. cheers

Hi , you could do it!
r1e0-----e0r2e1-----e0r3
area0 area1
you must config r2 two ospf routing process such as 10 and 20,
put r2e0 with area0 in process 10, and put r2e1 with area1 in process 20,
do this:
router ospf 20
netowork x.x.x.x x.x.x.x area 1
redistribute ospf 10 subnets
distribute-list 1 out ospf 10
access-list 1 permit x.x.x.x (which u want to propagate in area 1)
