when a interface is configure like this
frame-relay intf-type dce
frame-relay route 210 interface Serial2/0/7:0 110
frame-relay route 215 interface Serial3/1/14:0 115
frame-relay route 220 interface Serial2/0/18:0 120
frame-relay route 225 interface Serial1/1/4:0 125
is it considered a point to point or a point to multipoint..
i noticed that you can only specify point to point or multipoint if you use subinterfaces, so what does it default to when you dont use subinterfaces..

If you configure Frame Relay on the main physical interface instead of using subinterfaces it will be treated as a multipoint interface by default.
This config stands for frame relay switch or if you have router configured as frame relay switch so there should not be any question of point to point or multipoint cause this concept comes at CPE router.
Now if CPE router is not configured with subinterface then bydefault nature is multipoint.
