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.
