Hi all, This version addresses the issues Suresh rasied on the mailing list. (Many thanks to Suresh for a comprehensive review.)
The changes include: *Section 1: Add some texts on the motivation of the mechanism. *Section 3: Clarify that customer network behind the 4over6 CE could be IPv4-only or dual-stack; State that BR is also a DHCPv4 over IPv6 server/relay. *Section 4: Put some text to explain how Public 4over6 can integrate with DS-Lite. *Section 5.1: Improve the preciseness of the figure and the working flow described under the figure. *Section 6: Clarify the DHCPv6 option [RFC6334] that 4over6 CE uses to get the BR’s IPv6 address. Added a paragraph to describe the CE’s behavior of switching to DS-Lite. *Section 7: Remove the case that BR doesn’t participate the DHCPv4 over IPv6 process, for DS-lite integration consideration . Cheers, Peng.
