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 endusers 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
   leave a given router and then reenter that same router.  These
   procedures also accommodate IP multicast traffic that needs to travel
   to or from systems that are outside the EVPN domain.
