Can not ping to default route

[BooBam]

Here is a topology im working on, i have ospf on R1,R2,R3 and i have the INTERNET router as a default gateway on R1.

R1 and INTERNET can ping to each other, and all the other computers and routers can reach 209.108.1.2, but never 209.108.1.1 for some reason, the way i advertise default gateway on R1 is through "ip route 0.0.0.0 0.0.0.0 209.108.1.1" and then "default-information originate". still dosnt work, pls help!

Entire topology
