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.
