The IESG has approved the following document: - 'PBB-EVPN ISID-based C-MAC-Flush' (draft-ietf-bess-pbb-evpn-isid-cmacflush-09.txt) as Proposed Standard
This document is the product of the BGP Enabled ServiceS Working Group. The IESG contact persons are Jim Guichard, Andrew Alston and John Scudder. A URL of this Internet-Draft is: https://datatracker.ietf.org/doc/draft-ietf-bess-pbb-evpn-isid-cmacflush/ Technical Summary Provider Backbone Bridging (PBB) can be combined with Ethernet Virtual Private Networks (EVPN) to deploy Ethernet Local Area Network (ELAN) services in large Multi-Protocol Label Switching (MPLS) networks (PBB-EVPN). Single-Active Multi-homing and per-I-SID (per Service Instance Identifier) Load-Balancing can be provided to access devices and aggregation networks. In order to speed up the network convergence in case of failures on Single-Active Multi-Homed Ethernet Segments, PBB-EVPN defines a flush mechanism for Customer MACs (CMAC- flush) that works for different Ethernet Segment Backbone MAC (BMAC) address allocation models. This document complements those CMAC- flush procedures for cases in which no PBB-EVPN Ethernet Segments are defined (the attachment circuit is associated to a zero Ethernet Segment Identifier) and a Service Instance Identifier based (I-SID- based) CMAC-flush granularity is required. Working Group Summary Was there anything in the WG process that is worth noting? For example, was there controversy about particular points or were there decisions where the consensus was particularly rough? The document seemed to have broad consensus, nothing beyond that. Document Quality Are there existing implementations of the protocol? Have a significant number of vendors indicated their plan to implement the specification? Are there any reviewers that merit special mention as having done a thorough review, e.g., one that resulted in important changes or a conclusion that the document had no substantive issues? If there was a MIB Doctor, Media Type, or other Expert Review, what was its course (briefly)? In the case of a Media Type Review, on what date was the request posted? One known implementation exists, that was disclosed during the implementation poll Personnel The Document Shepherd for this document is Matthew Bocci. The Responsible Area Director is Andrew Alston. _______________________________________________ IETF-Announce mailing list IETF-Announce@ietf.org https://www.ietf.org/mailman/listinfo/ietf-announce
