The IESG has approved the following document: - 'Duplicate Address Detection Proxy' (draft-ietf-6man-dad-proxy-07.txt) as Proposed Standard This document is the product of the IPv6 Maintenance Working Group. The IESG contact persons are Brian Haberman and Ted Lemon. A URL of this Internet Draft is: http://datatracker.ietf.org/doc/draft-ietf-6man-dad-proxy/ Technical Summary 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 "split-horizon" forwarding scheme, primarily deployed for Digital Subscriber Line (DSL) and Fiber access architectures. Based on the DAD signalling, 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 replies instead of this last one. Working Group Summary The working group has reviewed and discussed this draft, feel it solves a relevant problem, and supports it becoming a standard. Document Quality This document has been reviewed by many people and the chairs believe there is agreement in the w.g. to move it forward. Personnel Bob Hinden is the Document Shepherd. Brian Haberman is the Responsible Area Director. RFC Editor Note OLD: When a node performs DAD for an address already used by another node, the first hop router replies instead of this last one. NEW: 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.
