I was able to reproduce this. If you do a show ip ospf data on R2 you will
se e the 0.0.0.0.
on R2, Go under the OSPF process and configure default
information-originate and you will see the default on R3.
Cheers,
RAM

Subject: Default router advertised by EIGRP
Hi, Group,
A straightforward question but I just can not figure it out.....
R1(s0)----EIGRP-----(s0)R2 (s1)----OSPF------(s0)R3
R1 : advertises a default route to its loopback0 via EIGRP
R2 : redistributed between EIGRP and OSPF
Question:
Why R3 does not receive the default route advertised by R1?
Below is my config and their routing table respectively:
R1#sh run
interface Loopback0
ip address 192.168.1.1 255.255.255.0
no ip directed-broadcast
!
interface Serial0

O E2 192.168.1.0/24 [110/50] via 10.1.1.2, 00:37:36, Serial0
R3#
Why R3 can not learn the default route advertised from R1??
Any hint are appreciated!
