[j-nsp] vpls remote mac learning on M20 on Junos 9.1?

Does anyone know why M20 would not learn remote (comming from a PE) MAC
addresses? I'm on Junos 9.1.
It is learning ce mac addresses. Also it is forwarding traffic in the ce->pe
direction, but everything coming from the pe side is not getting out on the
ce side.
I even put the sniffer between MX and M20 and see traffic comming from the
MX (pe side) with the proper demultiplexer label (there is no transport
label as routers are connected back to back). Transport is ldp.


On the other side I have an MX as PE and the MX is forwarding traffic just
fine in both directions. Is there any additional config that needs to be
enabled on the M20?
Thanks

Here is the M20 config and some show commands that show VPLS as UP.
