The IESG has approved the following document: - 'TRILL Smart Endnodes' (draft-ietf-trill-smart-endnodes-11.txt) as Proposed Standard This document is the product of the Transparent Interconnection of Lots of Links Working Group. The IESG contact persons are Alvaro Retana, Alia Atlas and Deborah Brungard. A URL of this Internet Draft is: https://datatracker.ietf.org/doc/draft-ietf-trill-smart-endnodes/ Technical Summary This draft addresses the problem of the size and freshness of the endnode learning table in edge RBridges, by allowing endnodes to volunteer for endnode learning and encapsulation/decapsulation. Such an endnode is known as a "Smart Endnode". Only the attached edge RBridge can distinguish a "Smart Endnode" from a "normal endnode". The smart endnode uses the nickname of the attached edge RBridge, so this solution does not consume extra nicknames. The solution also enables Fine Grained Label aware endnodes. Working Group Summary 1) 1st WG LC: 8/26 to 9/9/2016, extended to (10/4 to 10/18/2016) Problem/Resolution pots: https://mailarchive.ietf.org/arch/msg/trill/lnaBIR2dToAH8imcKYHWAsgHVN4 Resolution: https://mailarchive.ietf.org/arch/search/?email_list=trill&q=smart+end+nodes 2) Shepherd's comments caused a version-05 Posting of -05.txt: https://mailarchive.ietf.org/arch/msg/trill/82tCkCxuOnHRdRqP_YMKb6RCVfI [Shepherd Ack:] 3) July 2017 problem posting: (Donald Eastlakre) https://mailarchive.ietf.org/arch/msg/trill/PX-oOfyyksgc4yPSYnAhQrrJtjc [posting of -06.txt] to fix Donald comments https://mailarchive.ietf.org/arch/search/?email_list=trill&q=endnodes 4) Version 06 of the TRILL smart nodes Fixes the the issues in 2017 posting, and the hybrid "endnodes" complexity issue. The security considerations section provides the necessary security, but a query has been raised to the AD whether a summary of how this end node fits in other drafts. If the security ADs, are concerned with the group keying. the TRILL WG has a group keying solution (draft-ietf-trill-group-keying-01), and a specific adaptation of this to the draft-ietf-trill-link-gk-profiles-00.txt. If the security ADs feel this is important, they could adopt the draft-ietf-trill-group-keying-01 into the security dispatch area. Alia Atlas (AD) has spoken to the rtgwg area about taking on the trill-link-gk-profiles-00l.txt into the rtgwg for a parallel review. (Note this issue comes after the 1/19/2018 discussion with the Security ADs on routing security in routing drafts.] Document Quality This draft is part of the TRILL WG directory service work item. The lack of directory services was one of the major challenges deployments of TRILL have encounter in the field. This solution has prototype implementations in a few of the vendors.
