Abstract:

   In the Virtualization Overlay (NVO) network with Ethernet VPN (EVPN),
   optimized ingress replication uses Assisted-Replication (AR) to
   achieve more efficient delivery of Broadcast and Multicast (BM)
   traffic.  An AR-LEAF, which is a Network Virtualization Edge (NVE)
   device, forwards received BM traffic from its tenant system to an AR-
   REPLICATOR.  The AR-REPLICATOR then replicates it to the remaining
   AR-LEAFs in the network.  However, when replicating the packet on
   behalf of its multihomed AR-LEAF, an AR-REPLICATOR may face
   challenges in retaining the source IP address or including the
   expected Ethernet Segment Identifier (ESI) label that is required for
   EVPN split-horizon filtering.  This document extends the optimized
   ingress replication procedures to address such limitations.  The
   extended procedures specified in this document allow the support of
   EVPN multihoming on the AR-LEAFs as well as optimized ingress
   replication for the rest of the EVPN NVO network.
