Summary:  This draft is ready for publication as a Proposed
           Standard RFC.

Comments:

This document specifies OSPF for IPv6 networks.  It is very well written, clear overall, structured, and easily understandable.  I suggest this document to move forward in the publication process.
Few comments that should be addressed on this way:

(1)  The document, in particular abstract and introduction, is
      ambiguous on whether (a) it describes extensions/modifications
      to OSPF for IPv6 support, which would result in an OSPF version
      for both IPv4 and IPv6, or whether (b) it is a separate OSPF
      version specifically for IPv6.  The first sentence of the
      abstract implies (a).  But later the abstract implies (b),
      because it says that authentication mechanisms have been replaced
      by IPv6-specific ones, leaving no authentications means for IPv4.
      Then again, the increment of the OSPF version number specified in
      section 2.7 indicates that (a) is the case.  Please clarify the
      purpose and content of the document early in the abstract and
      introduction.

(2)  The document is very consistent WRT to introducing all acronyms
      (by spelling them out) when they appear first.  Do this for "LSA"
      also.  See 2nd paragraph of abstract.

(3)  In section 2.5, a special source address selection rule is
      defined for virtual links.  Is this rule needed specifically for
      OSPF, or is it specific to virtual links?  If the latter was the
      case, would it make sense to define this rule more generally in an
      IPv6 document?
