Dear all,

FYI, we have submitted this new I-D.

Comments, critiques, suggestions and questions are more than welcome.

As mentioned in the draft, the provisioning of the AFTR is a very sensitive for the delivery of the IPv4 connectivity when DS-Lite is enabled. Any failure to provision such information means the failure for the delivery of IPv4 services. Furthermore, the availability of the IPv4 connectivity services does not depend on the availability of DHCPv6 or RADIUS servers. 

The draft includes in the appendix a use case for further discussion: distribute DS-Lite serviced customers among a set of deployed AFTRs. Provisioning the AFTR with an RA option simplifies this task and removes a constraint on DHCPv6 servers (no need to know where the customer is connected from). Off-line tools can be used instead for tuning the content of the information to be conveyed in an RA option. This use case has been included in the I-D to discuss whether it is a valid use case or not. We will move this use case to the core text if it is believed to be a valid scenario.  

Cheers,
Med

A New Internet-Draft is available from the on-line Internet-Drafts directories.

	Title           : IPv6 RA Option for DS-Lite AFTR Element
	Author(s)       : Y. Lee, M. Boucadair
	Filename        : draft-lee-6man-ra-dslite-00.txt

This document specifies a new optional extension to IPv6 Router
Advertisement to allow IPv6 routers to advertise DS-Lite AFTR
addresses to IPv6 hosts.  The provisioning of the AFTR information is
crucial to access IPv4 connectivity services in a DS-Lite context.
Means to ensure reliable delivery of this information to connecting
hosts is a must.

Furthermore, this RA option can be used as a means to distribute DS-
Lite serviced customers among a set of deployed AFTRs without
requiring a central knowledge of the underlying topology and deployed
AFTRs.
