Abstract

The document describes a proxy-based mechanism allowing the use ofDuplicate Address Detection (DAD) by IPv6 nodes in apoint-to-multipoint architecture with a "split-horizon" forwardingscheme, primarily deployed for Digital Subscriber Line (DSL) andFiber access architectures. Based on the DAD signaling, thefirst-hop router stores in a Binding Table all known IPv6 addressesused on a point-to-multipoint domain (e.g., VLAN). When a nodeperforms DAD for an address already used by another node, thefirst-hop router defends the address rather than the device using theaddress.
