Hi All,
Thanks to all for your inputs.
SO in summary, there would be problems arising in this scenario, if the link
between area2 goes down and it is partitioned.
Which leads to my other question. What is the best way to solve this, by
using a virtual link or by using a tunnel?
As I mentioned if I use the tunnel, it does not seem to work. ANd with
virtual links I am not sure, if you can really implement it for
non-backboone area.
Smiles,
Mohit.

All of Area two should be directly connected and not
just by Area 0...discontiguous is bad. Better off to
make one of the Area 2s into Area 3. Get 100 routers
in each area re-converging when the link to Area 0
goes down and unable to directly communicate...it is
not pretty....and if you get a flapping
link...wehaa...and when you try to summarize ...more
fun...
