Hi Gopal,
External OSPF LSAs cannot be filtered on area basis. If the number of
internal routers in area 1 is less, You can use distribute-list in in
all area 1 routers or if possible redesign the network in a way to hav
all those routes in one area and use Type3 LSA filtering.
Regards,
Nagendra

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
