I am unclear what question you are asking -- is it how to link to
partitioned pieces of area 0.0.0.0 with a virtual link? Or are you
asking if this can be done (it can, with certain topologies) using
method other than a virtual link?
A virtual link solution indeed is possible, but I can't give you an
exact answer without knowing the specific topology.
Giving you an exact topology, however, isn't always the best way to
learn. Instead, let me give you a series of hints:
1. A virtual link must have one end in area 0.0.0.0, but that is
a minimum, not a maximum.
2. Virtual links can only transit area 0.0.0.0 or non-backbone areas
that are not using any kind of stubbiness.
3. Virtual links do interact with OSPF, so you must have OSPF
running in every router they traverse. If this is not the
topology, you need to use some non-OSPF tunneling mechanism.
4. If you repair a partitioned area 0.0.0.0 with a virtual link
that transits a non-backbone area, a router in each partition
must be able to reach the transit area.
