Abstract:
Ethernet VPN (EVPN) provides a service that allows a single Local
Area Network (LAN), i.e., a single IP subnet, to be distributed over
multiple sites. The sites 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 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.
