Spokes can ping each other because of the fram map command in each spoke pointed to the hub but the question ,if you advertised networks like loopback on each spoke , can the spokes see each other's rip routes in their routing tables while splite horizon is enabled on the hub interface?

On the hub router broadcast keyword would need to be used once per DLCI on the physical or sub point to multi-point interface. This will allow the routing updates to be passed on Frame Cloud. Split Horizon is needed for the hub to advertise the routes to the other spokes >From the email it seems like you use one OR the other and got it working? >Did the spokes actually hear routes of each other with split horizon enable?

Disabling Split horizon or adding the broadcast keyword in the frame-relay map subinterface command? The two ways works but for reference, which one is the Cisco choice?
