No, it's not. Flow mode is NOT packet mode and it doesn't really ever run packet mode in the current version. This has fundamental and significant impacts on the way packets are handled when being forwarded through the box which come with side-effects that cannot be overcome by mere configuration changes.
The Juniper ERX edge routers are what isn't "real" JunOS. It's as if they were trying to make a clone of the IOS CLI:
Those are not JunOS at all. They don't really try to pretend to be. The SRX and J-Series Services routers, OTOH, are most definitely pretending to be JunOS while not behaving like JunOS at certain fundamental levels. Owen
