Default Routes

I need some help debugging a configuration.

If I understand default routes correctly, they can be to an ip address / network (if a route already exists
for that address/network), or to an interface.

I have a physical frame-relay serial interface. Under that serial interface I have one point-to-point
subinterface that negotiates its ip address as well as having a Virtual Template assigned to it.

I want all unknown destination traffic to go out that subinterface. My config has a default
route to the physical serial interface and no traffic passes. Can/should that default route
point to the subinterface? If that's not possible, do I need to get the ip address on of the other end
of that link and use that in the ip route command? Note, ip routing is disabled.

Thanks for your help.

Below is sample config:
