Draft of message to be sent after approval:
From: The IESG <firstname.lastname@example.org> To: "Nevil Brownlee" <email@example.com> Cc: The IESG <firstname.lastname@example.org>, <email@example.com>, <firstname.lastname@example.org>, <email@example.com> Subject: Results of IETF-conflict review for <draft-lear-lisp-nerd-09.txt> The IESG has completed a review of <draft-lear-lisp-nerd> consistent with RFC5742. The IESG has concluded that this work is related to IETF work done in WG lisp, but this relationship does not prevent publication of 'NERD: A Not-so-novel EID to RLOC Database' <draft-lear-lisp-nerd-09.txt> as an Experimental RFC. The IESG would also like the RFC-Editor to review the comments in the datatracker (http://datatracker.ietf.org/doc/draft-lear-lisp-nerd/) related to this document and determine whether or not they merit incorporation into the document. Comments may exist in both the ballot and the history log.

Technical Summary LISP is a protocol to encapsulate IP packets in order to allow end sites to multihome without injecting routes from one end of the Internet to another. This memo presents an experimental database and a discussion of methods to transport the mapping of EIDs to RLOCs to routers in a reliable, scalable, and secure manner. Our analysis concludes that transport of of all EID/RLOC mappings scales well to at least 10^8 entries. Working Group Summary This document is an ISE submission. From the author: This draft has a bit of an odd history. First, NERD is actually the FIRST mapping ever defined for LISP. It had to block for a REALLLY long time (some years) on a normative reference. And let's face it: doing NERD without LISP would be using ketchup/vinegar without fries/chips (pick your venue). Then it got caught in the ISE changeover, and somehow or another got left in the wrong queue somewhere along the way, and blocked for another really long time. The reason it didn't go through the working group is that the working group didn't exist at the time, and I finished the work around the time the working group was being chartered. And of course when it was chartered, there was a quite narrow charter that didn't include NERD (and to be fair, I had moved on). Document Quality See the IESG note for suggested RFC 5742 text.
