Hello,

I support the WG adoption for draft-zhang-mpls-tp-pw-oam-config-06.

I think it would be useful having the OAM configuration taken care automatically by the control plane. Regarding some comments raising the fact that this was traditionally done by the NMS, this doesn't prevent to keep doing that in the traditional way. Moreover, the described configuration method is backward compatible.

We addressed the same problematic within CCAMP where we extended RSVP-TE for MPLS-TP OAM configuration but still keeping the possibility to do that via NMS. We even extended lsp-ping for such kind of configuration. All the 3 methods are simply working following a trivial precedence rule which prevents the risk of any overlapping between the 3.

Cheers,
Elisa
