Hi,
I will give it a try (I assume we are talking about MX-series). If you have a choice to replace Martini with Kompella then you could use VPLS with mac-learning turned off (which would be the same as L2VPN if you have only two sides in your VPLS). In this case you can just use flood filters and filter all BPDUs.
If this is not an option then I think (perhaps someone will correct me) there is no way to filter BPDUs on interface which is connected via L2 circuit.
Kind Regards
