Efficient Route Invalidation
RFC 9009, “Efficient Route Invalidation”, is a Proposed Standard document published in April 2021 by R.A. Jadhav, P. Thubert, R.N. Sahoo, Z. Cao. The canonical text is published by the RFC Editor.
Abstract
This document explains the problems associated with the use of No-Path Destination Advertisement Object (NPDAO) messaging in RFC 6550 and also discusses the requirements for an optimized route invalidation messaging scheme. Further, this document specifies a new proactive route invalidation message called the "Destination Cleanup Object" (DCO), which fulfills requirements for optimized route invalidation messaging.
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.
