Hi,
You need to verify the datalink(layer2) reachability first using network
layer address to verify. From your topology, it is assume that R1 is the
hub, R2 to R6 are spokes. It is assume that R1 has 5 dlci to reach R2 to R6.
It is assume that R2 to R6 each has one dlci and can only reach R1. The
first step you need to do is to ensure that R1(hub) can ping (spokes)R2 to
R6 and vice versa. Next you need to verify R2 to R6 (spoke to spoke). Afther
this is done.
Next it what routing protocols to run in this cloud, each has problem to
resolve.

Subject: Basic Frame Relay, RIP, and Split Horizon Question
I have a Hub and Spoke configuration setup as follows:
R1------FR-------R2
|
--------R3
|
--------R5
|
--------R6
All of the router's serial connections are in the
10.1.1.x/24 network. Each router's ethernet connection
is in a different class A network. Each router is
running RIP.
I can only ping the LAN interfaces of all
routers if I use point-to-point subinterfaces on the
spoke routers.
Is it possible to achieve this same connectivity
without using sub-interfaces? I tried using the 'no ip
split-horizon' command on the serial interface of the
hub router, (R1) but that does not seem to help.
Thanks,
Brad
