Hi Dino, I have no problems with the control plane part. An encap with multiprotocol support would allow to do IPsec encap before LISP encap, and could be used with the unauthenticated DH mechanism that you propose. I do really think that the LISP WG should not miss the encap debate, and drive the transition to a format that lends itself to the various use cases that are being envisioned (and that IMO should become the main focus of the WG asap). There's quite a broad support behind VXLAN-GPE, and LISP-GPE is an opportunity for LISP to capitalize on that support and maintain some backward compatibility with the current LISP encap and features.

And while generalization is nice, it often isn't practical. And what results in the marketplace is a subset of options being delivered in a general design that brings you back to the same result of having a specific format that would need to change later. > > Dino > >> On Dec 4, 2014, at 11:08 AM, Fabio Maino <fmaino@cisco.com> wrote: >> >> I don't support adoption of this document. >> >> The document is proposing an extension of the LISP header to support data plane security. However, there has been quite a lot of discussion in various WGs, including LISP, about the need for a more flexible overlay encapsulation. Besides support for data plane security, the requirements include capability to support non IP payloads, and to support metadata for various applications including service chaining and policy tags. >> >> I believe that rather than just adding incremental support for data plane security, the WG should have a comprehensive look at how to extend the LISP header to address the requirements above. draft-lewis-lisp-gpe, that was presented to the WG a few times, tries to address all of those requirements. >> >> Extending the semantic of the header to support data plane security, at least for HW implementations, comes at about the same cost of addressing all of the requirements above. I believe the same is true, to a lesser extent, even with SW implementations (at least those that deal with the encap in the kernel). >> >> Thanks, >> Fabio >> >> >> >> On 12/4/14, 3:27 AM, Luigi Iannone wrote: >>> Hi All, >>> >>> During the 91st IETF authors of the draft-farinacci-lisp-crypto-01 >>> [https://tools.ietf.org/html/draft-farinacci-lisp-crypto-01] >>> asked for WG adoption.
