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.
