The problem I face to is 10.200.1.1/24 network cannot go to internet
throught 10.1.1.1, and 10.201.1.1/24 also cannot go to internet throught
10.1.1.1.

s> network 10.200.1.0/24 area 0.0.0.10
s> network 10.201.1.0/24 area 0.0.0.20

don't use areas. area 0 for everything.

I'm not sure what your problem is and don't have experience with
areas, but there is no reason to use them other than to limit the size
of the SPF graph, and your network is too small to care about the size
of the SPF.

Not using areas will probably fix the problem. I would bet it is a
bug, but don't know.
