Do you have LDP enabled on Lo0 interface? Can you share pertinent config?<div><br></div><div>Cheers</div><div>Jide<br><br><br><a href="https://yho.com/footer0">Sent from Yahoo Mail for iPhone</a><br><br><p style="font-size: 15px; color: #715FFA; padding-top: 0; margin-top: 0">On Friday, April 22, 2016, 10:38 am, joel ahumuza <ahm.joel@gmail.com> wrote:</p><blockquote class="iosymail"><div dir="ltr">Hi All,<br>

We are experiencing an issue with ACX routers running on
12.3X54-D20.7 where the LDP sessions are continuously flapping, the
logs indicate the following;<br>
<br>
<small><small>Apr 21 03:36:31 hostname rpd[2299]:
RPD_LDP_SESSIONDOWN: LDP session x.x.x.x is down, reason: hold

<br>
Actions taken from our team was;<br>
- Increase the hold time setting on the ldp enabled interfaces.<br>
- Increase the time interval on the same ldp enabled interfaces.<br>
- setting the ldp session protection setting on the ldp enabled
loopback interface.<br>
<br>
Unfortunately the actions did not yield much since the flaps have
been ongoing.<br>
<br>
Anyone have any Idea on what the problem / solution might be?
