A new Request for Comments is now available in online RFC libraries. RFC 6957 Title: Duplicate Address Detection Proxy Author: F. Costa, J-M. Combes, Ed., X. Pougnard, H. Li Status: Standards Track Stream: IETF Date: June 2013 Mailbox: fabio.costa@orange.com, jeanmichel.combes@orange.com, xavier.pougnard@orange.com, lihy@huawei.com Pages: 16 Characters: 32537 Updates/Obsoletes/SeeAlso: None I-D Tag: draft-ietf-6man-dad-proxy-07.txt URL: http://www.rfc-editor.org/rfc/rfc6957.txt The document describes a proxy-based mechanism allowing the use of Duplicate Address Detection (DAD) by IPv6 nodes in a point-to-multipoint architecture with a "split-horizon" forwarding scheme, primarily deployed for Digital Subscriber Line (DSL) and Fiber access architectures. Based on the DAD signaling, the first-hop router stores in a Binding Table all known IPv6 addresses used on a point-to-multipoint domain (e.g., VLAN). When a node performs DAD for an address already used by another node, the first-hop router defends the address rather than the device using the address. This document is a product of the IPv6 Maintenance Working Group of the IETF. This is now a Proposed Standard. STANDARDS TRACK: This document specifies an Internet standards track protocol for the Internet community,and requests discussion and suggestions for improvements.
