Hello,
First, there is a partitioned area 2. This is not a lucky situation, but
should work. Ospf backbone treats the two area 2 as separate areas.
This is rather badly designed network and area placement than ospf
problem. ok, this is for the lab preparation and there anything can
happen. :)
But every inter area traffic has to go through the backbone anyway. So
its ok to go through the 2 serial links. So if you dont connect the two
area 2 and make the route intra area then the traffic will go through
the backbone. I think Sundar is right and a virtual link between R1 and
R2 through area 1 could reunite the discontigous area 2. And then there
would be an intra area route through the ethernet.
