You can further control the flow with:
[edit forwarding-options hash-key]
family inet {
layer-3;
layer-4;
}
family mpls {
label-1;
label-2;
}
If you're load balancing over a decent amount of hops I wouldn't hash
both layer-3/layer-4 and label-1/label-2 on every router because then
your per-flow becomes quite segregated and you might find issues where
your load balancing on many routers will break the seemingly load
balancing of another router since the hashing algorithm will produce the
same result on each router.

Subject: Re: [j-nsp] BGP and OSPF ECMP
Do you have a per-packet (really per flow) LB policy applied to the
forwarding table?
This is needed to install two or more forwarding paths in the pfe. BGP
multipath is a control plane tie breaker, but by default only one of the
winners is installed as active in the FT.
