LDP Extension for Inter-Area Label Switched Paths
RFC 5283, “LDP Extension for Inter-Area Label Switched Paths”, is a Proposed Standard document published in July 2008 by B. Decraene, JL. Le Roux, I. Minei. The canonical text is published by the RFC Editor.
Abstract
To facilitate the establishment of Label Switched Paths (LSPs) that would span multiple IGP areas in a given Autonomous System (AS), this document describes a new optional Longest-Match Label Mapping Procedure for the Label Distribution Protocol (LDP).
This procedure allows the use of a label if the Forwarding Equivalence Class (FEC) Element matches an entry in the Routing Information Base (RIB). Matching is defined by an IP longest-match search and does not mandate an exact match. [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.
