IPv6 Duplicate Address Detection Proxy is 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. In Split-horizon scenario where the hosts can not directly communicate with each other, but only through a BNG (Broadband Network Gateway).

Previously, when both “ipv6 nd proxy prefix connected” and VXLAN is configured for a VLAN interface, and the router received a Neighbor solicitation (NS) with an IPv6 address within the connected prefix of the router, the router replied with the interface physical (or virtual-router if VARP is configured) mac address as long as the NS is received on a local (front-panel) port. This feature extends the behavior to also include the NS received from the VXLAN tunnel.
