HELP ON FRAME-RELAY

[frankycool]

In My Packet Tracer Project, i'm trying to simulate 4 Networks in different geographic location Connected via WAN link.Due to cost which is a major step in this project we are required to select a WAN service that isn't to expensive for the company.So i decided to use Frame-Relay.So i inserted the cloud in the middle and connected all the 4 routers to it.Now my question is What routing protocol should i use? how Should i implement frame relay using this cloud so that they can be communication?

Please the attached file is the packet tracer network you can check to understand the flow and advice me

EDIT:

I did not realize this a training exercise, not a real design.

Yes its a training but still your advice will be somehow helpful

Choosing a routing protocol is not so important as some want to belive.

Recommend you use real routers or emulators for training.
