I haven't analyzed your topology, but just focusing on this statement:
"...running into a few issues with the OSPF route selction process of
preferring intra area over inter area routes."
--you can modify the AD of each type of OSPF route independently. See the
'distance ospf' command...

Subject: OSPF riddle -how to manipulate the OSPF prefer inter area over
intra area
Folks,
I have attached a topolgy that I am working on for simplicity, heres the =
problem -
I am trying to get a OSPF setup done and running into a few issues with =
the OSPF route selction process of preferring intra area over inter area =
routes. the requirement is that..The ISDN link between R2 and R5 shd be =
acctive only when the FR cloud is down. I am using OSPF demand circuit =
..Since R5 is now part of Area 1 the loopbacks on R2 and R4 are now seen =
as intra area routes and the ISDN route is prefferrd over the ethernet =
route. I tried to use the distance command and with one and then with =
two ospf process. Also an intersting thing here is that the External =
routes for RIP and EIGRP are also learnt through the BRI even after =
canging the redistributed route type to E1 to include internal cost. I =
am not if I am missing something here
R3 is connected via Ethernet to the Area 0. I forgot to put that on the =
drawing.
My configurations are simple..partial configs
R5
router ospf 1
network 150.35.15.0 0.0.0.255 area 0
network 50.1.1.0 0.0.0.255 area 1
network 5.5.5.0 0.0.0.255 are 0
router-id 5.5.5.5
redistribute eigrp 1 subnets route-map eigrp2ospf
R2
router ospf 1
network 150.35.24.0 0.0.0.244 are 1
network 50.1.1.0 0.0.0.255 are 1
network 2.2.2.0 0.0.0.255 are 1
redisribute rip subnets route-map rip2ospf
Interface bri 0/0
ip add 50.1.1.2 255.255.255.0
ip ospf demand circuit
ip ospf cost 1500
