Are you sure we are talking about same thing. This thread is about 20bit IPv6 header Flow Label. I feel like you're talking about FAT pseudowires?
Yes right, but the lookup principle is the same either you look at IPv6 flow label or you look at the Entropy label.
By default JNPR will in pseudowire transit look for IP keys, with or without FAT. Optionally it can look even with existence of CW. You need to specifically ask it not to look for IP keys in pseudowires or add CW (and not explicitly tell it to look).
We didn't use FAT PWs, but rather entropy labels for VPNv4 traffic. adam
