Q: How can I give preference to OSPF inter-area routes over intra-area routes?
A. According to RFC, the order of preference for OSPF routes are as follows:
intra-area routes, O
inter-area routes O IA
external routes type 1, O E1
external routes type 2, O E2

Joe,
Was looking at ur diagram.By default OSPf will prefer
the O path over IA path.If u change ur bandwidth on
serial link to reflect the 64K which ur figure says,it
should work.Does that sound correct ?
Let us know.HTH.
