Path-type There are four possible types of paths used to route traffic to the destination, listed here in decreasing order of preference: intra-area, inter-area, type 1 external or type 2 external. Intra-area paths indicate destinations belonging to one of the router's attached areas. Inter-...

After dividing the network into areas and configuring routers, each area can be categorized according to its characteristics in the network. We have the following OSPF Area types: *Backbone Area Backbone area is the area meeting place for all other areas in the OSPF network. This area is often...

An area routing capability is provided, enabling an additional level of routing protection and a reduction in routing protocol traffic. In addition, all OSPF routing protocol exchanges are authenticated. The differences between this memo and RFC 2178 are explained in Appendix G. All differences are ...
Note: The broadcast and non-broadcast network types elect a DR/BDR. Summary link LSA (Type 3)– ABRs generate this LSA to send between areas (so type 3 is called inter-area link). It gathers information it has learned on one of its attached areas and summarizes them before sending out...
Configure Stub and Not-So-Stubby Area Types This task explains how to configure the stub area and the NSSA for OSPF. Procedure Step 1 configure Example: RP/0/RP0/CPU0:router# configure Enters mode. Step 2 Do one of the following: router ospf process-name ro...

I would say given what you've have explained that each floor wont be a transit for any other and that you are redistributing bgp prefixes I think it would be beneficial to go down the a totally stub area for each access floor, this will provide and advertise only a default ...
