George Time Warner Cable November 13, 2014 Enhanced Duplicate Address Detection - draft-ietf-6man-enhanced-dad-09 + draft-ietf-6man-enhanced-dad-10 Abstract IPv6 Loopback Suppression and Duplicate Address Detection (DAD) are discussed in Appendix A of RFC4862. That specification mentions a hardware-assisted mechanism to detect looped back DAD messages. If hardware cannot suppress looped back DAD messages, a software solution is required. Several service provider communities have expressed a need for automated detection of looped backed Neighbor Discovery (ND) messages used by DAD. This document includes @@ -163,21 +163,21 @@ o Looped back message - also referred to as a reflected message. The message sent by the sender is received by the sender due to the network or an Upper Layer Protocol on the sender looping the message back. o Loopback - A function in which the router's layer-3 interface (or the circuit to which the router's interface is connected) is looped back or connected to itself. Loopback causes packets sent by the interface to be received by the interface and results in interface unavailability for regular data traffic forwarding. See - more details in section 9.1 of [RFC2178]. The Loopback function + more details in section 9.1 of [RFC2328]. The Loopback function is commonly used in an interface context to gain information on the quality of the interface, by employing mechanisms such as ICMPv6 pings and bit-error tests. In a circuit context, this function is used in wide area environments including optical Dense Wave Division Multiplexing (DWDM) and SONET/SDH for fault isolation (e.g. by placing a loopback at different geographic locations along the path of a wide area circuit to help locate a circuit fault). The Loopback function may be employed locally or remotely. @@ -468,21 +468,21 @@ describing the use cases. 9.
