Fiddling with timers won't change this: the message is "Peer closed the
session" because "BGP Notification Received", so it's a deliberate reset
that's coming from the other end, rather than a network failure.

Hi,
Would anyone have any ideas why this BGP is flapping two or so
times a day?

Nothing fancy in the config, just usual template peer-session and
peer-policy. Anyone else having this issue? Platform is ASR1k
running 03.14.01.S (15.5.1 S1). Latency to the peer is around 300
ms in average, due to it being in US. I did try different timers
but it didn’t resolve the issue, just slowed it down.
Cheers,
Dino
