I have a basic question on advertising Loopback in OSPF:
Let's say there are three areas exist on an router -
R1 has Area 0,1,2 with Loopback 192.168.0.1/32 R2 has Area 0 with
Loopback 192.168.0.2/32R3 has Area 0,3 with Loopback 192.168.0.3/32
How do you decided where to advertise loopback address?

Normally, I would advertise all Loopback's in area 0. Is there a criteria to
adverstise loopbacks on ABR?
Can anyone sheds some light on this?
