I have 3 routers in three areas.
R1 ---> Area 0
R2 ---> Area 0 and 1 (ABR)
R3 ---> Area 1.
R2 is connected to R3 (in area 1)through a FR,with 'ip ospf net point-to-point' configured. I try to filter inter- area routes from area 0 from entering area 1 by applying the below command at the serial interface of R2 connecting to R3....'ip ospf database-filter all out'. Bur I am still seeing the IA routes. Please whats the reason.
