You can advertise a default from R1 also as:
router ospf 1
default-information originate always
You can block R3 to see this default as:
router ospf 1
distribute-list 1 in <int_from_R1>
!
access-list 1 deny 0.0.0.0
access-list 1 permit any
This way, R2 will see the default but R3 will not.
2) - you might use conditional advertsement which I need to try first...

Subject: directed default route
Hello group,
Is it possible to send the default route to just one router???
Say I have this topology. Between R1 R2 and R3 is ospf. all routes to
this domain are coming from R3 router. Between R1 and R4 is ISDN and
from R1 to
R4 is the default route with the AD of 200. I need to do so that when
the link between R1 and R3 is down alltraffic is going out to R4. From
R1 it will go since there is a static default route to R4. How could I
advertise the default route to R2 from R1??? could anybody suggest
something??
R3-R1 -R2
|
R4
Sure better if R3 would not see this default.
Thanks,
