Organization: IETF
Publication Date: 1 June 2013
Status: active
Page Count: 5
scope:

The document describes a proxy-based mechanism allowing the use of Duplicate Address Detection (DAD) by IPv6 nodes in a point-tomultipoint 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 pointto- 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.
