<div dir="ltr"><div>It's set to the International standard (ANSI) @least on the Cisco side., which should be correct for multivendor, if you change to PPP, does the flap stops? try debuging (with care). Also can you clear the counters so we know what kind of errors if any is happening? What is bouncing? just the sub-interface/BGP or the main POS is also flapping? What does the Juniper see?</div>

Hi,<br>
<br>
Am having a problem that is buffling.<br>
<br>
I recently changed a POS link encapsulation from PPP to Frame-relay.<br>
Since that time the POS interface keeps resetting from time to time.<br>
<br>
On my BGP session am receiving cease notifications from my upstream<br>
provider.<br>
<br>
The setup is such that we have a cisco on one end and a Juniper on the<br>
other.<br>

If I remember correctly, the frame-relay setting on a cisco is proprietary to cisco. You need to set both sides to a standard protocol both devices adhere to.<br>
<br>
Also, are these connected back-to-back? Or, are they connected to an ILEC switching device?<br>
