Customer A is on the ge-7/2/0 vlan 512, customer B is on the ge-7/2/1 vlan 512i.

Interface has to have vlan-tagging and encapsulation vlan-ccc under interface itself, and encapsulation vlan-ccc under the unit.
BGP must have family l2vpn signaling
routing-instances configure instance-type l2vpn, include interface pointing to the customer interface ge-N/N/N, route-distinguisher, vrf-target, protocols l2vpn encapsulation-type ethernet-vlan, interface unit as protocols l2vpn interface ge-N/N/N.UNIT, site identifier, and interface unit again under the site stanza.
