<div dir="ltr">Hi All,<br>
<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
time expired<br>
Apr 21 03:36:34 hostname rpd[2299]: RPD_LDP_NBRDOWN: LDP
neighbor x.x.x.x (lo0.0) is down<br>
Apr 21 03:36:38 hostname rpd[2299]: RPD_LDP_NBRDOWN: LDP
neighbor x.x.x.x (lo0.0) is down<br>
Apr 21 03:36:38 hostname rpd[2299]: RPD_LDP_SESSIONDOWN: LDP
session x.x.x.x is down, reason: all adjacencies down<br>
Apr 21 03:55:34 hostname rpd[2299]: RPD_LDP_SESSIONDOWN: LDP
session x.x.x.x is down, reason: received notification from peer<br>
Apr 21 03:55:34 hostname rpd[2299]: RPD_LDP_SESSIONDOWN: LDP
session x.x.x.x is down, reason: received notification from peer<br>
Apr 21 03:55:35 hostname rpd[2299]: RPD_LDP_SESSIONDOWN: LDP
session x.x.x.x is down, reason: received notification from peer<br>
Apr 21 03:55:35 hostname rpd[2299]: RPD_LDP_SESSIONDOWN: LDP
session x.x.x.x is down, reason: received notification from peer</small></small><br>
<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?
