The IESG has received a request from the BGP Enabled ServiceS WG (bess) to consider the following document: - 'EVPN Optimized Inter-Subnet Multicast (OISM) Forwarding' <draft-ietf-bess-evpn-irb-mcast-09.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 2023-10-05. 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 Ethernet VPN (EVPN) provides a service that allows a single Local Area Network (LAN), comprising a single IP subnet, to be divided into multiple "segments". Each segment may be located at a different site, and the segments are interconnected by an IP or MPLS backbone. Intra-subnet traffic (either unicast or multicast) always appears to the end users to be bridged, even when it is actually carried over the IP or MPLS backbone. When a single "tenant" owns multiple such LANs, EVPN also allows IP unicast traffic to be routed between those LANs. This document specifies new procedures that allow inter-subnet IP multicast traffic to be routed among the LANs of a given tenant, while still making intra-subnet IP multicast traffic appear to be bridged. These procedures can provide optimal routing of the inter- subnet multicast traffic, and do not require any such traffic to egress a given router and then ingress that same router. These procedures also accommodate IP multicast traffic that originates or is destined external to the EVPN domain.
