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

What type fpc is in that M20?  I believe a B2/efpc is needed for lsi
type interfaces, such as needed for no-tunnel services config. In the
past I have seen this blackhole vpls traffic coming in from the core.

I assume you have no tp hardware? If you did worth loosing the
no-tunnel. 

Send OP of a show chassis hardware....

Subject: [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.
