Choon,
 
Have you try to put the tunnel0 interface in R2 and R3 into area 0 ?
I saw your config, the tunnel is in area 3.
 
Rgds,

Hi,

I lab-up the following Scenario for OSPF:

Area 0 | R2 -----Area 1------- R5 ------Area 2--------R3--------| Area 3

Everything works fine... but, my ping drop intermittently when I try to
ping from Area3 to Area0.
Anything wrong with my configuration?

Thanks.

Following is my configuration:
