Great news!
Full support and looking forward to working with the DT team!

Based on the presentation by Greg Mirsky and discussion in rtgwg and elsewhere, I have decided to charter a fast-moving Routing Area design team to work on Overlay OAM.

The charter is below:

In the Routing Area, several WGs (e.g. NVO3, BIER, and SFC) are working on relatively new encapsulations to create overlays. These overlay or service encapsulations are transport-independent since they may be over different transports or at different layers in the networking stack. Each WG is starting to discuss what OAM and tools need to be developed (see draft-ietf-sfc-oam-framework-00, draft-ietf-bier-oam-requirements-00, and individual drafts in NVO3). With increasing use of overlay and service layer tunnels, extensions to traceroute to allow visibility into multiple layers are being discussed (e.g. draft-nordmark-nvo3-transcending-traceroute-01).

There is an opportunity to propose protocols and methods to provide Overlay OAM in a sufficiently generic fashion that they can meet the requirements and be applied to at least BIER, NSH, VXLAN-GPE, GENEVE, and GUE. A truly successful result would also be applicable to other technologies.

This Design Team is chartered to first produce a brief gap analysis and requirements document to focus its work on protocol extensions. This should be published by March 2016. With that basis, this Design Team is chartered to rapidly propose extensions to existing IETF OAM protocols such as those discussed in [RFC 7276] and new ones to support the requirements for OAM from NVO3, BIER, and SFC. The Design Team will produce an initial proposal by IETF 95. It is expected that the initial proposal will provide guidance to additional people who will be interested in working on the details and gaps.

The Design Team will consider the preliminary OAM requirements from NVO3, BIER, and SFC. The Design Team should align with the LIME WG's work on common YANG models of OAM.

The members of the design team are:
   Greg Mirsky (DT lead)
   Ignas Bagdonas
   Erik Nordmark
   Carlos Pignataro
   Mach Chen
   Santosh Pallagatti
   Deepak Kumarde
   David Mozes
   Nagendra Kumar Nainar

The design team has a private mailing list that will be publicly archived.
The mailing list is [e-mail]<mailto:[e-mail]>.

The design team will also use a wiki to track some information.  Others are also welcome to comment and interact there.
The wiki is at:  http://wiki.tools.ietf.org/area/rtg/trac/wiki/RtgOoamDT
