1.  Introduction

   This memo defines various OSPF registries for IANA to set up and
   maintain for OSPF code points.  In some cases, this memo defines
   ranges of code point values within these registries; each such range
   has a different assignment policy.

   The terms used in describing the assignment policies are as follows:

      o  Standards Action

      o  Experimentation

      o  Vendor Private Use

      o  Reserved

   Standards Action means that assignments in that range MUST only be
   made for Standards Track RFCs (as defined in [RFC2434]).

   Some of the registries defined below reserve a range of values for
   Experimentation.  For guidelines regarding the use of such values see
   [RFC3692].  Values from this range MUST NOT be assigned by IANA.
   Further guidance on the use of the Experimentation range may be found
   in paragraphs 4, 5, and 6 of [RFC3692].  An implementation MAY choose
   to not support values from the Experimentation range.  In such a
   case, the protocol data structure with a code point from the
   Experimentation range is ignored, unless other protocol machinery
   says how to deal with it.  "Ignored" in this context means that the
