Hi guys,
 
This is the topology:
 
area 0 sw1 area 47 R4 area 0 --> rest of network
                              ^
                              |
                      totally stubby
 
                ^ ^
                |------ gre tunnel ----------|
 
 
 
R4 has all the routes from the rest of the network including routes (E2 and
IA) that were redist into ospf from other protocols.
 
Here's the question:
 
What routes should sw1 see?
 
Should sw1 see external routes?
 
Inter-area routes?
 
Should sw1 have a default route from R4?
 
TIA, Tim
