I don't know > how well it works in practice. It works okay for IP traffic. But we've had issues with it working for Layer 2 traffic which is carried in an EoMPLS pw. We had to workaround this by switching from "adaptive" to "per-packet". I know what you're thinking - no, we have not had any "per-packet"-related issues, as the downlink device to which the traffic is being sent is local within the data centre. All the hashing features and algorithms that were present simply could not handle hashing outbound Layer 2 traffic equally. Juniper seemed to indicate some improvements for this in Junos 15, but 14.2 has been super stable for us and we'd like to keep it that way.
