Can you try configuring interface as next-hop rather then giving ip address
. May be your both ip addresses reachable from both the interfaces so using
only one link.Also pls check in Juniper load balancing is per flow not per
packet so your outgoing traffic load balancing in many cases is influenced
by your incoming traffic.
