This is a fun problem, and it would be too easy for me just to
give the answer away. Therefore, I just have a little hint to add.
The "network" statement in IGP does *NOT* mean what networks you
are advertising. The network statement is used to specify which
interfaces you are running that protocol on.
Think about it.
