Once after ISSU lo0 filter dropped LDP, another time after ISSU one particular customer filter was dropping things it should not have, forcing reprogramming helped in both case. And yeah, probably is going to be challenging to reproduce. I wonder if implementations even try to verify correctness, do they ask HW about state they just changed/added/removed, to confirm what code asked actually did occur. Not picking on Juniper here, I've seen various HW programming issues in other vendors too. -- ++ytti ___ juniper-nsp mailing list juniper-nsp@puck.nether.net https://puck.nether.net/mailman/listinfo/juniper-nsp

This sounds like activating enhanced-ip and forgetting to reboot the box immediately after it. I never saw this type of issue caused by upgrades.

Updated from 14.2 to 15.1R here (on several MX, same RE hardware). Didn't see this issue. Any particular stuff in your filters ? > Le 18 sept. 2016 à 09:18, Chuck Anderson a écrit : > > Has anyone upgraded from 14.2 to 15.1 and seen this issue?
