I'm trying to setup two 2524 routers using two V.35 serial cables to simulate frame relay. I found a document on Cisco website. However, even if I follow the instruction it doesn't work. The following is my config.
************************************
R1
frame-relay switching
interface Serial0
ip address 172.16.120.105 255.255.255.0
encapsulation frame-relay
frame-relay map ip 172.16.120.120 101 broadcast
clockrate 64000
frame-relay intf-type dce
R2
Interface Serial0
ip address 172.16.120.120 255.255.255.0
encapsulation frame-relay
frame-relay map ip 172.16.120.105 101 broadcast
*********************************
Serial Interface is showing up/down on both side. show frame-relay pvc is showing pvc is inactive.
Any suggestion? I'm running 12.1 IOS.
Thanks.

You need to disable keepalives in back-to-back frame-relay setup for the interface to come up. Configure 'no keepalive' under s0 on both routers.

By doing that, I'm able to bring up two interfaces. However, I'm still not able to ping across. Am I missing something?
Thanks.

Create a point-to-point sub-int and use the frame-relay interfac-dlci command instead of the frame-relay map commands.
Use this document for reference.

Sundar,
I'm still not able to ping from R1 to R2 serial interface.
Thanks.
