               OSPFv2 Prefix/Link Attribute Advertisement
                draft-ietf-ospf-prefix-link-attr-09.txt

Abstract

   OSPFv2 requires functional extension beyond what can readily be done
   with the fixed-format Link State Advertisements (LSAs) as described
   in RFC 2328.  This document defines OSPF opaque LSAs based on Type-
   Length-Value (TLV) tuples that can be used to associate additional
   attributes with prefixes or links.  Dependent on the application,
   these prefixes and links may or not be advertised in the fixed-format
   LSAs.  The OSPF opaque LSAs are optional and fully backward
   compatible.
