IS-IS Route Leaking/Redistribution

Hello,
 
Hoping someone can shed some light on a scenario I've been working on:
 
R1---R2---R3---R4
 
OSPF Area 0 between R1 and R2
IS-IS Level 1 between R2 and R3 (same area)
IS-IS Level 2 between R3 and R4 (different areas)
 
R3 is receiving Level 2 IS-IS routes from R4 which I then leak into
IS-IS Level 1 using
 
Redistribute isis level-2 to level-1 distribute-list 100
Access-list 100 permit ip any any
 
I am trying to redistribute the IS-IS inter-area routes into OSPF on
router R2:
 
redistribute isis level-1 subnets
 
R1 is only receiving one level-1 route (which shows as L1 in R2's
routing table), but it is not receiving any of the IS-IS inter-area (ia)
routes.
 
Is it even possible to redistribute leaked inter-area routes on a L1
router into another routing protocol? It seems to me that this would be
incorrect and
R2 should actually be a level-2 router.
 
Any help would be appreciated.
