Technical Summary

   This document defines enhancements to the OSPF protocol to support a
   new class of link-state advertisements (LSA) called Opaque LSAs.
   Opaque LSAs provide a generalized mechanism to allow for the future
   extensibility of OSPF. Opaque LSAs consist of a standard LSA header
   followed by application-specific information.  The information field
   may be used directly by OSPF or by other applications.  Standard OSPF
   link-state database flooding mechanisms are used to distribute Opaque
   LSAs to all or some limited portion of the OSPF topology.

   This document replaces RFC 2370 and adds to it a mechanism to enable
   an OSPF router to validate AS-scope opaque LSAs originated outside of
   the router's OSPF area.

Working Group Summary

   No dissent reported (see PROTO writeup by Acee Linden). This 
   document provides clarifications to RFC2370, with the one 
   technical change (see immediate paragraph above) having been
   discussed in the WG.
