Routing Extensions for Discovery of Multiprotocol Label Switch Router Traffic Engineering Mesh Membership
RFC 4972, “Routing Extensions for Discovery of Multiprotocol Label Switch Router Traffic Engineering Mesh Membership”, is a Proposed Standard document published in July 2007 by JP. Vasseur, JL. Leroux, S. Yasukawa, S. Previdi, P. Psenak, P. Mabbey. The canonical text is published by the RFC Editor.
Abstract
The setup of a full mesh of Multi-Protocol Label Switching (MPLS) Traffic Engineering (TE) Label Switched Paths (LSP) among a set of Label Switch Routers (LSR) is a common deployment scenario of MPLS Traffic Engineering either for bandwidth optimization, bandwidth guarantees or fast rerouting with MPLS Fast Reroute. Such deployment may require the configuration of a potentially large number of TE LSPs (on the order of the square of the number of LSRs). This document specifies Interior Gateway Protocol (IGP) routing extensions for Intermediate System-to-Intermediate System (IS-IS) and Open Shortest Path First (OSPF) so as to provide an automatic discovery of the set of LSRs members of a mesh in order to automate the creation of such mesh of TE LSPs. [STANDARDS-TRACK]
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.
