RE: IPv6 w.g. Last Call on "Deprecating Site Local Addresses"



Title: RE: IPv6 w.g. Last Call on "Deprecating Site Local Addresses"

I am generally happy with the document after reviewing it.  I found a number of fairly trivial nits, plus one wording query:

Section  2.3, first para - also an editorial nit in same para:
In the first para the draft says:
   The ambiguity of site local addresses also creates problems for the
   routers. In theory, site local addresses are only used within a
   contiguous site, and all routers in that site can treat them as if
   they were not ambiguous. In practice, problem occurs when sites are
                                         -------
                                         the problem  
   disjoint, or when routers have to handle several sites

I am not sure that the word 'disjoint' is right here.  When I read it I wasn't sure whether the intention was to callout situations where 'sites' overlapped and the word 'not' was missing.  The next sentence clarifies that we a dealing with sites which are partitioned but the components are not directly connected.   I think partitioned might be a better description.

Editorial nits:

Section 1: It might be desirable to add 'unicast' to site local on the first occurrence (as this what the discussion has been about) and would be desirable for the second occurrence.

Section 2.2, para 3:
   The experience with RFC1918 addresses also shows some non trivial
   leaks, besides pacing these addresses in IP headers. Private
                  ------ s/b
                  placing

Section 2.2, last para:
The second sentence may be a little too colloquial.

Section 2.3, 4th para:
 In multi-homed routers, such as for example site border routers, the
   routing process should be complemented by a filtering process, to
   guarantee that packets sourced with a site local address never leave
   the site. This filtering process will in turn interact with the
   routing of packets, as it may cause the drop of packets sent to a
                                           ----
                                           dropping

Section 2.5: Spurious blank line in 1st para.

Section3:
Non-ambiguous should be hypenated throughout - currently there is a mixture of hyphenated and non hyphenated(sic).

Section3, last para:
   One question remains, anycast addressing. Anycast addresses are
   ambiguous by construction, since they refer by definition to any
   host that has been assigned a given anycast address. Link-local or
   global anycast addresses can be"baked in the code".
                                 ---- missing space
