for some reason if you need to use static routes ….

ip route 192.168.1.0 255.255.255.0 s0/0

with the exit interface on your own router, this is much more efficient as there are not recursive lookups

or

ip route 192.168.1.0 255.255.255.0192.168.100.1

pointing to the next hop ip address, less efficient due to the recursive lookup

If you are after a default route then

ip route 0.0.0.0 0.0.0.0 [exit interface | next hop interface]
