I support this draft as a good basis for ARP/ND optimization and reducing unknown unicast flooding as well as detection of forged source addresses. I am not aware of any IPR other than that which has already been disclosed. Looking at the overall draft, in the Pull Directory section, there are four different message types. While these all have a common header, the remainder of the message can be various different things, commonly zero or more instances of a record structure. Exactly what the remainder of the message is can depend on whether the error field in the header is zero or non-zero or on flags in the header. While I do not think there is any technical problem here, I believe a table and section summarizing the different cases would add clarity to the draft. (In addition, the typos and clarifications pointed out by Gayle Noble should be incorporated.) Thanks, Donald ============================= Donald E.
