Hi Alucard, There is an ongoing effort to implement these features on OpenBSD. The control plane for ldpd(8) is already done, I just need some time to polish the patches and send them for review. If you want to help with testing please let me know. As for the data plane, I'm now in touch with Rafael to support him with his implementation. He will need to change a few things in order to support both the VPWS and VPLS solutions. For example, claudio@ suggested using one virtual interface per pseudo wire and use our bridge(4) for the VPLS stuff (mac learning, flooding, ageing, etc). We hope to finish things up soon.
