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.
