The IESG has received a request from the BGP Enabled ServiceS WG (bess) to consider the following document: - 'PBB-EVPN ISID-based CMAC-Flush' <draft-ietf-bess-pbb-evpn-isid-cmacflush-07.txt> as Proposed Standard
The IESG plans to make a decision in the next few weeks, and solicits final comments on this action. Please send substantive comments to the last-c...@ietf.org mailing lists by 2023-07-11. Exceptionally, comments may be sent to i...@ietf.org instead. In either case, please retain the beginning of the Subject line to allow automated sorting. Abstract 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. The file can be obtained via https://datatracker.ietf.org/doc/draft-ietf-bess-pbb-evpn-isid-cmacflush/ No IPR declarations have been submitted directly on this I-D. _______________________________________________ IETF-Announce mailing list IETF-Announce@ietf.org https://www.ietf.org/mailman/listinfo/ietf-announce
