Autonomous System Migration Mechanisms and Their Effects on the BGP AS_PATH Attribute
RFC 7705, “Autonomous System Migration Mechanisms and Their Effects on the BGP AS_PATH Attribute”, is a Proposed Standard document published in November 2015 by W. George, S. Amante. It updates RFC 4271. The canonical text is published by the RFC Editor.
Abstract
This document discusses some existing commonly used BGP mechanisms for Autonomous System Number (ASN) migration that are not formally part of the BGP4 protocol specification. It is necessary to document these de facto standards to ensure that they are properly supported in future BGP protocol work.
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.
The canonical text of RFC 7705 is hosted at rfc-editor.org. Available in TXT,HTML.
