point to Multipoint vs NBMA

I need to know the difference between NBMA and point to multi point.
when a router(hub) and other routers(spokes) communicate through a Cloud(frame relay)they can be connected point to point, point to multi point and NBMA. how do we determine which mode we should go with?
thanks

If I understood:
1-Frame relay is NBMA (Non Broadcast Multiple access).
do you have an example of its configuration if you don't want to simulate Broadcast?
2-in Frame relay you can set up point to point subinterfaces or point to multipoint subinterfaces.
example of configuration for point to point in Frame relay
example of configuration for point to multipoint in frame relay.

3-By the way I have heard of frame relay, ATM. or MPLS, which one is better ?

Thanks

So NBMA is just a type of network (usually refers to a frame relay).
And the NBMA network can be Point to Point, Point to Multipoint,Broadcast.

that s what I concluded from this discussion
