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.

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.
