The IESG has approved the following document: - 'Optimized Ingress Replication Solution for Ethernet VPN (EVPN)' (draft-ietf-bess-evpn-optimized-ir-12.txt) as Proposed Standard This document is the product of the BGP Enabled ServiceS Working Group. The IESG contact persons are Alvaro Retana, John Scudder and Martin Vigoureux. A URL of this Internet Draft is: https://datatracker.ietf.org/doc/draft-ietf-bess-evpn-optimized-ir/ Technical Summary Network Virtualization Overlay (NVO) networks using EVPN as control plane may use Ingress Replication (IR) or PIM (Protocol Independent Multicast) based trees to convey the overlay BUM traffic. PIM provides an efficient solution to avoid sending multiple copies of the same packet over the same physical link, however it may not always be deployed in the NVO core network. IR avoids the dependency on PIM in the NVO network core. While IR provides a simple multicast transport, some NVO networks with demanding multicast applications require a more efficient solution without PIM in the core. This document describes a solution to optimize the efficiency of IR in NVO networks. Working Group Summary The document was developed to address the desire to provide efficient replication. It is important because it avoids the need to deploy PIM in the core of the network only for this application, which is particularly a consideration where EVPN is deployed to implement Network Virtualization Overlays in data centers. It makes use of a new BGP PMSI Tunnel Type to do this. Document Quality The document has been widely reviewed and discussed on the list over a number of years. There are known implementations. Personnel The document shepherd is Matthew Bocci (matthew.bocci@nokia.com). The responsible Area Director is Martin Vigoureux (martin.vigoureux@nokia.com).
