I used a router as a frame-relay , but the interface serial 0/0 protocol is always down , could any one please help me out
here is the config for it

Hi
r u using this as a frame relay switch
if yes thn the config is different for this

no i am using a 2600 router , and when i shutdown the serial interface it comes up for like 10 sec and then its down again

In addition to what John and Peter suggested, make sure you are only clocking the DCE site. To know which side is DCE, do a "sh cont s0/0"
If it is on older serial interfce, the clock rate usually is 64000
Are you connecting the routers back to back using a DTE, DCE cable?

Hello Mahmood,
Why do you believe so? The configuration of the router as a Frame Relay switch as posted here is perfect. I see nothing wrong with it. The clock rate is a little curious (what kind of Serial interfaces is being used here?) but otherwise, the configuration is just fine.
Mostafa, can you post the output of the following commands?
show ip interface brief
show frame-relay pvc
show frame-relay route
show int s0/0
show int s0/1
show int s0/2
Thank you!
Best regards,
Peter

Can you post the other side? Is this in production or a lab, and which interface is up/down? Generally, incorrect encapsulation on either end can cause this problem. If you're doing this in a lab and you have it connected back to back without a frame relay switch in between, you'll need to disable keepalives with "no keepalive" on the serial interfaces on both ends of the link.
HTH,
John
