In order to avoid inter-area loops, OSPF stipulates that it is not allowed to advertise routing information directly between two non-backbone areas. It is only allowed to advertise routing information within an area or between a backbone area and a non-backbone area. Therefore, each area border router (ABR) must be connected to the backbone area.
