IRR & Routing Policy Configuration Considerations
<draft-ietf-grow-irr-routing-policy-considerations-04>
Abstract
The purpose of this document is to catalog past issues influencing
the efficacy of Internet Routing Registries (IRR) for inter-domain
routing policy specification and application in the global routing
system over the past two decades. Additionally, it provides a
discussion regarding which of these issues are still problematic in
practice, and which are simply artifacts that are no longer
applicable but continue to stifle inter-provider policy-based
filtering adoption and IRR utility to this day.
