  1. IPv6 Inverse Neighbor Discovery draft-ietf-ion-ipv6-ind-03.txt Alex Conta Alex Conta - IPv6 IND

  2. Inverse Neighbor Discovery - IND • Extension to Neighbor Discovery - inverse discovery • based on known link layer address - request destination IP address • correspond to IPv4 Inverse ARP (RFC 2390) • use the same type of messages as ND • add new option - list of IP addresses • Application • Frame Relay Networks (or other links) - IPv6 similar for IPv4 Inverse ARP • Status • passed ION WG Last Call • with feedback from the IESG: • published new draft (draft-ietf-ion-ipv6-ind-03.txt) • moved Frame Relay specifics info in Appendix section. • aligned the IND option (List of IP addresses) with ND options • allow list of IP option in Solicitation • remove use of O bit Alex Conta - IPv6 IND
