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 with mpls-te, and is'n work when change igp (ospf) cost for only ldp signalling. All labels is correct on the both directions and signaling are correct - L2 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 on 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 configurations of 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.
