If have two ospf process ids on one router, you have to have
two ospf processes. Each should have its own set of interfaces
by which they talk to other routers.
(You can not share the same interface by two ospf processes)
All routers that share the same area over one link will form
adjacencies,
and synchronize their topology of that area. ABR's will link different
areas into one routing domain. This should (in a real world network)
all inside one AS...
You could have one router running 2 OSPF processes, one using some
interfaces
and the other using others. They would have different databases, and you
could
use redistribution between them to exchange routing information if you
will.
