OSPFv2 Prefix/Link Attribute Advertisement
RFC 7684, “OSPFv2 Prefix/Link Attribute Advertisement”, is a Proposed Standard document published in November 2015 by P. Psenak, H. Gredler, R. Shakir, W. Henderickx, J. Tantsura, A. Lindem. The canonical text is published by the RFC Editor.
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 OSPFv2 Opaque LSAs based on Type-Length-Value (TLV) tuples that can be used to associate additional attributes with prefixes or links. Depending on the application, these prefixes and links may or may not be advertised in the fixed-format LSAs. The OSPFv2 Opaque LSAs are optional and fully backward compatible.
What “Proposed Standard” means
An entry-level standards-track specification: stable, peer-reviewed and a solid basis for implementation, though it may still evolve before becoming an Internet Standard.
