Thanks Kasturi,
it works!
If I change the routing protocol between R2 and R3 to RIP
R3 gets the default route from R1 directly
It seesm to me OSPF views routing table code
D*EX
'*' ( candidate default) over 'D' (EIGRP)
this route for OSPF is viewed as a 'default route' , not a EIGRP route
this route for RIP is viewed as a EIGRP so it redistributed by R2 directly.

Subject: Re: Default router advertised by EIGRP
Configure Default-info originate on R2 so that R3 can get it. This as i
understand is the def behaviour of OSPF. even though u have a def route on
r2,OSPF wont advertise it into OSPf areas.
See Page 758 of Jeff doyle Rotuing TCP Vol1 for the case study with e.g. Let
us know.
Good Luck,
Kasturi.
