Hi, Tried as follows;
liam@NA-QFX5110-1# show interfaces xe-0/0/9 description "Temp Link to Arista"; vlan-tagging; mtu 9216; encapsulation flexible-ethernet-services; unit 123 { encapsulation vlan-ccc; vlan-id 123; input-vlan-map pop; output-vlan-map push; family ccc; } liam@NA-QFX5110-1# show protocols l2circuit neighbor 192.168.68.3 { interface xe-0/0/9.123 { virtual-circuit-id 123; no-control-word; ignore-mtu-mismatch; pseudowire-status-tlv; } } liam@WN-MX204-1# show interfaces xe-0/1/3 description "ISPCO-WN-PVE-1 C0/F3 enp6s0f1"; flexible-vlan-tagging; mtu 9216; encapsulation flexible-ethernet-services; unit 123 { encapsulation vlan-ccc; vlan-id 123; input-vlan-map push; output-vlan-map pop; family ccc; } liam@WN-MX204-1# show protocols l2circuit neighbor 192.168.68.5 { interface xe-0/1/3.123 { virtual-circuit-id 123; no-control-word; ignore-mtu-mismatch; pseudowire-status-tlv; } } When I removed the l2circuit encapsulation altogether from both ends I got an EM -- encapsulation mismatch on the l2circuit I also tried encapsulation internetworking / ethernet-vlan / ethernet At some point I did get mac learning both ways in that at the QFX end I could see mac from the MX end, but haven't successfully managed to pass icmp / ping.

That might be the go and rebuild some l2circuits from scratch. https://www.juniper.net/documentation/en_US/junos/topics/reference/general/mpls-limitations-qfx-series.html *(QFX5100, QFX5110, QFX5120, QFX5200, QFX5210, EX4600) When VLAN bridge encapsulation is enabled on a CE connected interface, the switch drops packets if both flexible Ethernet services and VLAN CCC encapsulations are configured on the same logical interface. Only one can be configured, not both. For example:set interfaces xe-0/0/18 encapsulation flexible-ethernet-services, or set interfaces xe-0/0/18 encapsulation vlan-ccc.* As mentioned the above might be causing me issues, as I did have some sub interfaces running vlan-bridge alongside the vlan-ccc interface on xe-0/0/9.
