Hello
On our LNS, we have some log errors about some PPP sessions over VPDN that cannot come up.
we have 3 LNS and all of them are impacted, not all PPP sessions are impacted and L2TP tunnels are still up.
Here is the error message :
Oct 13 2022 10:03:27.304: %VPDN-6-CLOSED: L2TP LNS t2e04a closed Vi3.179 user KY46890@; Result 1, Error 0, Dataplane down
Has someone faced this before ?
Kind regards

Hello
I want to share with you the issue after it has been resolved :
The issue was on ASR-1009K router, we don't know for the moment if only this model is impacted. This is due to implementing those flowspec commands on our routers :

The router has just few sessions (not even 1000) and we already tried the reload/reboot. But still having the same issue.
