You cannot simulate frame-relay with 2 routers. A minimuim of three are required. One router must serve as the frame-relay switch. This router needs to be connected to both other routers via back-to-back serial connections.
In many ways, frame-relay is analogous to IP. It's just one more set removed. In frame-relay, a router will segment data into frame-relay packets and address them using the DLCI. These packets are sent to the frame-relay provider. The frame-relay provider's equipment (referred to as a switch) passes the packet to another switch based on the DLCI. I don't really know how many switches a common frame-relay packet goes through, but it doesn't really matter, because it will come out in the right place on the other router. The other router accepts the data, reassembles it into the original form and routes it accordingly. The trick is, frame-relay was never meant to operate back-to-back. Therefore, each router needs to be directly connected to a frame-relay switch. I don't have a link to help in that configuration, but if you get a third router, I can dig something up.
