[rbak-nsp] BGP Flapping after flag recive

[Olivier Benghozi]

In 2011 the issue was with an AGGREGATOR attribute with AS 0.

So it's something else here.
Maybe like https://lists.gt.net/nsp/juniper/35537 <https://lists.gt.net/nsp/juniper/35537> ?

You'll have to capture the session and/or debug bgp on the Smartedge to have some more information about the route at problem, I guess.
