Re: [v6ops] Adam Roach's No Objection on draft-ietf-v6ops-transition-ipv4aas-12: (with COMMENT)

Hi Adam,

I just replied to Ben comments, and I already did to Mirja, so don't think I can add anything else on that point.

I missed the BCP point on the response to Ben, so here is it.

My understanding is that BCP is a "current practices". Some of the considerations in the document are new. No new protocols (that's why is info), but new requirements to put "together" in a CE existing protocols and how to take advantage of "coordinating" them, so the operator can deploy IPv4aaS, or even change from dual-stack to IPv4aaS, or one IPv4aaS technology to another or have different customers with different IPv4aaS technologies, etc.

This means that, for clarity, we have text that may seem redundant if you already know all the details of each of the IPv4aaS technologies, but it makes very easy for an operator to have a single document to "follow the path" in a coherent way.

This is part of the scope of v6ops chapter, providing guidance for the deployment of and operation of new and existing IPv6 networks.

Let me know if this clarify your point on this.

Thanks!

Regards,
Jordi

    COMMENT:
    ----------------------------------------------------------------------

    I share Ben and Mirja's question about the formal relationship between this
    document and RFC 7084.

    I also share Ben's confusion about the document's status as not being a BCP --
    statements like the following are, by my understanding of the term, specifying
    practices that are considered to be "best" at the present time:

    * "The IPv6 Transition CE Router MUST implement a DNS proxy as
      described in [RFC5625] (DNS Proxy Implementation Guidelines)."

    * "The IPv6 Transition CE Router MUST support the DHCPv6 S46
       priority options described in [RFC8026]."

    * "The IPv6 Transition CE Router MUST have a GUI, CLI and/or
       API option to manually enable/disable each of the supported
       transition mechanisms."

    If these (and similarly phrased) statements are not recommending best current
    practices, then I don't understand the purpose of this document.
