[j-nsp] Junos BNG PPPoE inside a VPLS

[Adrien Desportes]

Hello William,

Before 13.2 you would have to use an external loop to terminate the vpls on one side and the ppp on the other side (as lt- interface does not support the proper encapsulation for ppp).

Starting 13.2 (that was just released), if you use L2VPN rather than VPLS to backhaul your DSLAM VLAN, the below feature might do the job w/o consuming ports for the external hairpin:
