QFX5110 problem with passing through mpls traffic/l2circuit

    We started the implementation of QFX5110 and faced the problem that there is no traffic inside l2circuit if the path goes through QFX. It's not work with the mpls-te, and is'n work when change igp (ospf) cost for only ldp signalling. All labels is coreect on the both directions and signaling are correct - l2circuit is up, but there is no ping inside the channel. at the same time, If mpls hop is mx80-cisco-cisco-cisco l2circuit works correctly. Also we have some mx80 – it implementation well – l2circute works with path mix with cisco and mx.
    We check some firmware 18.4r1, 18.4r2, 19… now it's 19.4R3-S2.2.
    We experiment with interfaces:
    Unit with mpls p2p, l2 switching with irb and l3-int on vlan
    Perhaps someone has some ideas on how to make the device work with the declared functionality.
