Dear authors,
Thanks for the new version.
I had a quick read on latest version. I find some nits and also some questions along the way as we meet a scenario when deploying MAP that need s46 radius attributes.

Section 7.1 should be referring section 3.x not 4.x
[Med] Thank you for catching the bug in Section 7.1.

1. How is the status of this document? This draft has last called long time ago, but still not standard yet. What is the reason? Any plans to move further? As I mentioned we meet requirement when deploying map, we may need to make a decision if we follow this draft or define a vendor specific one.

[Med] The document passed the WGLC + addressed the reviews from radext wg. We do think that the document is ready to be sent to the IESG.

2. This draft seems haven't consider conflicts between subscribers. E.g.  EA length conflict between subscribers with in one MAP domain? And EA length from radius conflict with BNG within same MAP domain?
As this draft enables the capability to maintain MAP rule logic in radius, conflict mechanisn should be investigated in my POV.

[Med] Which conflict mechanism do you have in mind?

I’m afraid this is deployment and implementation-specific. FWIW, the draft includes the following to warrant that some consistency checks is needed:

   In some deployments, the DHCP server may use the Accounting-Request
   to report to a AAA server the softwire configuration returned to a
   requesting host.  It is the responsibility of the DHCP server to
   ensure the consistency of the configuration provided to requesting

Appreciate your feedback.
Thanks in advance

   IPv4-over-IPv6 transition mechanisms provide IPv4 connectivity
   services over IPv6 native networks during the IPv4/IPv6 co-existence
   period.  DHCPv6 options have been defined for configuring clients for
   Lightweight 4over6, Mapping of Address and Port with Encapsulation,
   and Mapping of Address and Port using Translation unicast softwire
   mechanisms, and also multicast softwires.  However, in many networks,
   configuration information is stored in an Authentication,
   Authorization, and Accounting server which utilizes the RADIUS
   protocol to provide centralized management for users.  When a new
   transition mechanism is developed, new RADIUS attributes need to be
   defined correspondingly.

   This document defines new RADIUS attributes to carry Address plus
   Port based softwire configuration parameters from an Authentication,
   Authorization, and Accounting server to a Broadband Network Gateway.
   Both unicast and multicast attributes are covered.
