Harbir, try this method of building a frame-relay switch from two 2501
routers (assuming FRS1 and FRS2 are connected S0-to-S0 as in your first
attempt, and routers are connected to S1 on each FRS):
FRS1

interface Tunnel12

tunnel destination 12.12.12.2

interface Serial0
ip address 12.12.12.1 255.255.255.0
!
interface Serial1
no ip address
encapsulation frame-relay
clockrate 2000000
frame-relay intf-type dce
frame-relay route 104 interface Tunnel12 401
FRS2

Or E0-E0 back-to-back with full-mesh DLCIs would allow you to connect up to
4 routers with any combination of point-to-point or multipoint:

That's it for the frame-relay switch. Now you have to config the routers.
This is a good drill, but really recommend you buy a router with 4 or more
serial ports to be your frame-relay switch.
