Technical Summary

    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.

Working Group Summary

     There has been much discusson about the protocol operations
      when the extended prefix TLVs appear multiple times in the OPAQUE 
      LSA and different flooding scope of the extended Prefix LSA.
 
      As a result of the discussion, the document has been updated with 
      details of receive side handling for all the cases along with 
      recommended behaviours for send side to minimize disruptions 
      in the network.

      This document has been a WG document for a little under one year.
      It is stable, without changes to the technical solution for more
      than three months. 

      Additionally, the document has been successfully implemented by
      interoperability tested by multiple vendors as indicated by the 
      implementation status section.
