Yeah... I ran into the same issue before. I had to set the clock rate on the DCE side as Scott said. I noticed that it was only with the 2500/2600 series... Why is that?
 
Thanks,

If you're connecting two 2500 series devices back to back, you'll need a clock rate on the DCE side.  In addition, if you aren't using a frame switch in the middle, you'll want to do "no keepalive" on both serial links.
 
As a note, in your configs below, those interface types aren't what you'd see on a 2500.  :)

Here is a quick config highlighting the frame-relay portion for on of the e-scenarios.  I am connecting two 2500 routers via a DTE/DCE serial cable.  The issue that I am running into is that the line comes up for a few seconds and then the serial interface goes down on the DTE side.  When I issue a show frame-relay pvc command, the DLCI shows as being deleted.  Am I missing something?  I was able to get it to work for a few minutes the other day but not since then.  Thanks, Jamie
