This document defines enhancements to the OSPF protocol to support a new
class of link state advertisements (LSAs) 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 Autonomous System (AS)-scope Opaque
LSAs originated outside of the router's OSPF area.  [STANDARDS TRACK]
