The IESG has approved the following document: - 'TRILL: ESADI (End Station Address Distribution Information) Protocol' (draft-ietf-trill-esadi-09.txt) as Proposed Standard This document is the product of the Transparent Interconnection of Lots of Links Working Group. The IESG contact persons are Ted Lemon and Brian Haberman. A URL of this Internet Draft is: http://datatracker.ietf.org/doc/draft-ietf-trill-esadi/ Technical Summary: ESADI (End Station Address Distribution Information) is an optional protocol implemented at TRILL switches by which they can communicate, in a Data Label (VLAN or Fine Grained Label) scoped way, end station addresses and other information to TRILL switches in the TRILL campus participating in ESADI for that Data Label. This document updates the specification of the ESADI protocol that appears in RFC 6325, the TRILL base protocol specification, and is not backwards compatible because it changes the format of ESADI-LSPs. Working Group Summary: There was no particular controversy. Before the initial WG Last Call on the -02 draft there was a late IPR disclosure filed. There were WG Last Call comments leading to editorial and technical changes resulting in the 03 draft which was determine to have WG consensus. The -03 draft increased the number of fragments in an ESADI-LSP and, as a result of document Shepherd review, the WG was asked if it wanted to change to the standard method for doing this which was progressing as draft-ietf-isis-fs-lsp. Based on WG support for this change, a -04 draft was produced and a 2nd WG LC starting on 27 November 2013. During this WG LC a specific technical problem with a corner case was uncovered and it was suggested that an expanded explanation of how this document will update the TRILL base specification [RFC6325] should be included. A fix to this technical problem and the expanded "updates" explanation were included in in the -05 draft which was WG Last Called on 8 Feb 2014 and determined to have consensus. Document Quality: The shepherd doesn't know of existing implementations. There has been significant review of this document on the TRILL WG mailing list with multiple WG last calls. Personnel: Document Shepherd: Erik Nordmark Responsible Area Director: Ted Lemon Although this document creates an additional IANA sub-registry, it does not require expert review, hence no experts are proposed.
