Sorry that I just read Fred's email about 184 emails on this topic.  I
got thrown off seeing no v6ops in the draft name above.  I have seen the
discussions on 6rd sunsetting but those are mostly general discussions.
As Barbara said an SP deploys 6rd or DS-Lite, so why bother for 6rd,
DS-Lite, and native dual-stack coexistence?  

 

The document is incomplete.  Let's consider only IPv6 for now. There is
an SRIB, DFIB, and a Policy Table.  Additionally the CE does have a FIB.
Where are the details for how does the FIB interface with the SRIB,
DFIB, and the Policy Table?  There are 24 combinations (4!) of results
between the FIB, SRIB, DFIB, and the Policy Table.  Which combination is
used to forward a packet?  Some conclusions below.

 

 

(a)    it is questionable if the work is even needed because the SP
deploys one of 6rd and DS-Lite and one needs simpler 6rd sunsetting or
DS-Lite sunsetting, and 

(b)    draft-townsley-troan-ipv6-ce-transitioning-02 is not ready to be
adopted as a WG document.

 

Rfc6204bis can't be held up due to
draft-townsley-troan-ipv6-ce-transitioning-02. 

 

Further, isn't draft-townsley-troan-ipv6-ce-transitioning-02 specifying
technology or is there another document that covers the technology in
more detail?  Technology documents need to move to a different WG.
