OSPF Extensions in Support of Generalized Multi-Protocol Label Switching
Overview
RFC 4203, “OSPF Extensions in Support of Generalized Multi-Protocol Label Switching”, is a Proposed Standard document published in October 2005 by K. Kompella, Y. Rekhter. It updates RFC 3630. It has since been updated by RFC 6001, RFC 6002, RFC 7074. The canonical text is published by the RFC Editor.
Abstract
This document specifies encoding of extensions to the OSPF routing protocol in support of Generalized Multi-Protocol Label Switching (GMPLS). [STANDARDS-TRACK]
