Hi,
distribute-list out only works on ASBR and will filter the specified routes
from getting advertising into OSPF domain itself.

Nagendra

Hi Amit,
Thanks for the reply,
But I dont agree on the point that Dist list out on R1 will stop LSA Type
5 to go in to R2 and so on to All Area 1and hence creating their Routing
Table..
Any Comments.....
Thanks Gopal

RE: OSPF External Routes filtering
Gopal,
I guess we could use distribute list in out direction under OSPF process
of
Router R1 from preventing to go in Area1 Coz R1 has one arm in A1 and one
in
A0. So it'll receive routes but will not let them in A1

Hi All,
A quick question on OSPF,
suppose i have Rotuer <--(Area 0)R1(Area 1)---->(Area
1)R2------>(Cloud of
Area 1)
Now suppose somehow, Area 0 has some External routes redistributed by BGP
in to ospf, say 10 Routes.
I want to block 5 routes out of 10 from going into Area 1 but they should
be appearing in Area 0 or any other area; how is it possible????Any Idea
will be appreciated.
****Distribute-list in Wont work, coz it will stop on R2 Router only, if
configured on R2 and not for whole Area 1****
Thanks & Regards,
Gopal
