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
