You may filter at ABR’s. But OSPF has a requirement that devices IN an area have the same database.
You can always use another protocol or another process on the devices you want to have those routes with. but either way, it’s a per-router configuration (like distribute-lists).

Hello to all CCIE candidates! I’ve the following topology:
lo:1.1.1.x->R1—R2—-R3
R1 - area 1 R2 - ABR R3 - area 0
The issue that I want that 1.1.1.x will not be advertised to the R2(ABR) and all other routers int area 0. So the problem here is that I want to find workaround to filter route in intra- area and not on ABR with area 1 range 1.1.1.0 255.255.255.0 not-advertise command. Also because there are about 20 routers in area 0 that shouldn’t receive 1.1.1.x and I don’t want to use distribute-list x in on each router in area 0 to filter the local routing table on each router.
May be some of you have any suggestion how to get this workaround?
