Advertisement of Multiple Paths in BGP
Overview
RFC 7911, “Advertisement of Multiple Paths in BGP”, is a Proposed Standard document published in July 2016 by D. Walton, A. Retana, E. Chen, J. Scudder. The canonical text is published by the RFC Editor.
Abstract
This document defines a BGP extension that allows the advertisement of multiple paths for the same address prefix without the new paths implicitly replacing any previous ones. The essence of the extension is that each path is identified by a Path Identifier in addition to the address prefix.
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.
