Routing

Hi,

I would like to filter STP BPDUs on L2 circuit (not on VPLS), but I did not find solution for that.

Can you help me, please?

Thx a lot in advance!

Kind regards,

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

If this worked for you please flag my post as an "Accepted Solution" so others can benefit. A kudo would be cool if you think I earned it.

Just if some1 will bump into this problem. right now you can filter over l2circuits with this:

unit 41 {
    encapsulation vlan-ccc;
    vlan-id 41;
    family ccc {
        filter {
            output L2_VLL;
        }
    }
}

(just add family ccc into interface configuration and add family ccc filter to it; works as a charm on MX)
