Nokia Nokia Ribbon Communications HPE Assisted Replication (AR) is an optimized ingress replication solution for Ethernet VPN (EVPN) Broadcast and Multicast (BM) traffic. AR offloads the replication effort from ingress Network Virtualization Edge (NVE) devices onto Assisted Replication Replicators (AR-REPLICATORs). The base AR specification is focused on Network Virtualization Overlay (NVO) networks that use IP tunnels, and it is typically deployed for Virtual eXtensible Local Area Network (VXLAN). EVPN services can also be instantiated over Segment Routing over IPv6 (SRv6); however, the SRv6 EVPN transport specification supports only ingress replication for BUM traffic, and the AR procedures rely on IP-tunnel semantics (such as the tunnel source and destination IP addresses) that do not map exactly to an SRv6 data plane. As a result, AR cannot be readily deployed over SRv6 tunnels. This document specifies the applicability of Assisted Replication to SRv6 tunnels, for EVPN BM traffic, for selective multicast based on Internet Group Management Protocol (IGMP) and Multicast Listener Discovery (MLD) proxy, and for EVPN IP multicast traffic based on Optimized Inter-Subnet Multicast (OISM). It defines a new SRv6 Endpoint behavior for the AR-REPLICATOR role and the associated control-plane procedures, so that the AR solution can be used with an SRv6 underlay.
