Forwarding end-to-end lacp accross l2circuit (EX4550)

Hi all

I have setup l2circuit between two juniper EX4550 running 12.3R12-S7, at the end at each EX, CPE is connected, the CPE port is on lacp, do by default lacp traffic will be forward or tunnel end-to-end accross l2circuit ? if no how can I achieve this with is junos version ?

Thanks for your reply.
