Internet Engineering Task Force (IETF) A. Ghanwani Request for Comments: 8293 Dell Category: Informational L. Dunbar ISSN: 2070-1721 M. McBride Huawei V. Bannai Google R. Krishnan Dell January 2018 A Framework for Multicast in Network Virtualization over Layer 3 Abstract This document provides a framework for supporting multicast traffic in a network that uses Network Virtualization over Layer 3 (NVO3). Both infrastructure multicast and application-specific multicast are discussed. It describes the various mechanisms that can be used for delivering such traffic as well as the data plane and control plane considerations for each of the mechanisms.

Informational [Page 2] RFC 8293 A Framework for Multicast in NVO3 January 2018 1. Introduction Network Virtualization over Layer 3 (NVO3) [RFC7365] is a technology that is used to address issues that arise in building large, multi- tenant data centers (DCs) that make extensive use of server virtualization [RFC7364]. This document provides a framework for supporting multicast traffic in a network that uses NVO3. Both infrastructure multicast and application-specific multicast are considered. It describes variousShow full document text
