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.
