Proto-write-up for draft-ietf-l1vpn-basic-mode-04

Intended status : Standards Track

Recommend that this I-D is progressed in parallel with three other
I-Ds:
- draft-ietf-l1vpn-applicability-basic-mode
- draft-ietf-l1vpn-bgp-auto-discovery
- draft-ietf-l1vpn-ospf-auto-discovery

Adrian Farrel is the document shepherd.
He has personally reviewed the I-D and believes it is ready for
forwarding to the IESG for publication.

> (1.b)  Has the document had adequate review both from key WG members
>        and from key non-WG members?  Does the Document Shepherd have
>        any concerns about the depth or breadth of the reviews that
>        have been performed?

Authors are key in the field.

Draft acknowledges contributions from all the WG chairs.

WG review by key implementers has been OK with feedback on the list and
in WG meetings. WG last call was quiet, but this reflects the fact that
most of the work had already been done, and the protocol extensions are
not extensive.

> (1.c)  Does the Document Shepherd have concerns that the document
>        needs more review from a particular or broader perspective,
>        e.g., security, operational complexity, someone familiar with

No concerns.

> (1.d)  Does the Document Shepherd have any specific concerns or
>        issues with this document that the Responsible Area Director
>        and/or the IESG should be aware of?  For example, perhaps he

The document is sound.

> (1.e)  How solid is the WG consensus behind this document?  Does it

>        others being silent, or does the WG as a whole understand and

There were no problems with consensus for this document.

> (1.f)  Has anyone threatened an appeal or otherwise indicated extreme
>        discontent?  If so, please summarise the areas of conflict in
>        separate email messages to the Responsible Area Director.  (It
>        should be in a separate email because this questionnaire is
>        entered into the ID Tracker.)

No threats. No discontent.

> (1.g)  Has the Document Shepherd personally verified that the
>        document satisfies all ID nits?  (See
>        http://www.ietf.org/ID-Checklist.html and
>        http://tools.ietf.org/tools/idnits/).  Boilerplate checks are
>        not enough; this check needs to be thorough.  Has the document
>        met all formal review criteria it needs to, such as the MIB
>        Doctor, media type and URI type reviews?

All checks made.

> (1.h)  Has the document split its references into normative and
>        informative?  Are there normative references to documents that
>        are not ready for advancement or are otherwise in an unclear
>        state?  If such normative references exist, what is the
>        strategy for their completion?  Are there normative references
>        that are downward references, as described in [RFC3967]?  If
>        so, list these downward references to support the Area
>        Director in the Last Call procedure for them [RFC3967].

References split.
No downrefs.

> (1.i)  Has the Document Shepherd verified that the document IANA
>        consideration section exists and is consistent with the body
>        of the document?  If the document specifies protocol
>        extensions, are reservations requested in appropriate IANA
>        registries?  Are the IANA registries clearly identified?  If
>        the document creates a new registry, does it define the
>        proposed initial contents of the registry and an allocation
>        procedure for future registrations?  Does it suggest a
>        reasonable name for the new registry?  See [RFC2434].  If the

>        can appoint the needed Expert during the IESG Evaluation?

This is a Standards Track I-D, but makes no requests for IANA action.
A null IANA section is present.

>        document that are written in a formal language, such as XML

No such sections.

This document describes the Basic Mode of Layer 1 VPNs (L1VPN BM).
L1VPN Basic mode is a port-based VPN. In L1VPN Basic Mode (BM), the
basic unit of service is a Label Switched Path (LSP) between a pair
of customer ports within a given VPN port-topology. This document
defines the operational model using either provisioning or a VPN
auto-discovery mechanism, and the signaling extensions for the L1VPN
BM.

Nothing of note.
There was some juggling of definitions between this I-D and the two
autodiscovery I-Ds (draft-ietf-l1vpn-bgp-auto-discovery, draft-ietf-
l1vpn-ospf-auto-discovery) as they all three need to encode the same
data elements. The end result was that this I-D contains the encoding
expressed in a protocol-neutral away.

The protocol described in this I-D is largely specified in RFC 4208
which is itself almost entirely a restatement of RFC 3473. RFC 3473 is
widely implemented and well enough deployed. RFC 4208 has been deployed
in a small number of cases, and specific interoperability has been
shown in private labs and at an interoperability event.

The signaling mechanisms to build a L1VPN service have been shown
experimentally by several vendors. In some cases this has required
configuration of the PITs, and in other cases it has used auto-
discovery, but that distinction is not germane to this I-D. Interop
demos of L1VPN services have been performed, and several service
providers are actively looking at the technology and the business case.
