Hi,
To get a basic frame-relay network up perform the following:
1) Use your 2521 as Frame Switch - you have it configured already
2) Use 4 routers for your frame-relay network
3) Physically cable the 4 routers to the 2521:
2521 S0 (DCE) to R1 S0 (DTE)
2521 S1 (DCE) to R2 S0 (DTE)
2521 S2 (DCE) to R3 S0 (DTE)
2521 S3 (DCE) to R4 S0 (DTE)
The way your 2521 is currently configured R1 will be a Hub router
and R2,R3 and R4 will be spokes.
If you will be using 2500's as your spoke routers I would change the
clockrate on S0 and S1 on your 2521 to 64000. I usually just use 64000 but
that is a matter of choice. What is listed next is a basic config for each
of your routers. These configs should get your frame-relay network running
with no frills. I will just use physical
interfaces on all the routers and inverse arp. The final topology will be
hub and spoke all in one network.

To verify connectivity do the following:
1) On the 2521 - show frame route
You should see all the connections active
2) On R1 - show frame map
You should see three dynamic mappings to your spokes
- show frame pvc
You should see 3 active and used DLCI's (112,113,114)
3) On your spoke routers R2,R3 and R4 - show frame map
You should see one dynamic mapping to your hub
- show frame pvc
You should see 1 active and used DLCI
4) Ping from your hub to each spoke
5) Ping from each spoke to your hub
With these configs you will not be able to ping spoke to spoke. If you want
this capability just add frame-relay map statements on each of your spokes
pointing to the other spokes.
____________________________________________________________________
Let me know if you are successful. Once you get the frame network up and
running then the fun really begins. Proceed to configure routing protocols
like EIGRP and OSPF over your frame network.
Best of luck.
