The IESG has received a request from the BGP Enabled ServiceS WG (bess) to consider the following document: - 'A Network Virtualization Overlay Solution using EVPN' <draft-ietf-bess-evpn-overlay-10.txt> as Proposed Standard The IESG plans to make a decision in the next few weeks, and solicits final comments on this action. Please send substantive comments to the ietf@ietf.org mailing lists by 2017-12-22. Exceptionally, comments may be sent to iesg@ietf.org instead. In either case, please retain the beginning of the Subject line to allow automated sorting. Abstract This document specifies how Ethernet VPN (EVPN) can be used as a Network Virtualization Overlay (NVO) solution and explores the various tunnel encapsulation options over IP and their impact on the EVPN control-plane and procedures. In particular, the following encapsulation options are analyzed: VXLAN, NVGRE, and MPLS over GRE. This specification is also applicable to GENEVE encapsulation; however, some incremental work is required which will be covered in a separate document. This document also specifies new multi-homing procedures for split-horizon filtering and mass-withdraw. It also specifies EVPN route constructions for VxLAN/NvGRE encapsulations and ASBR procedures for multi-homing NV Edge devices. The file can be obtained via https://datatracker.ietf.org/doc/draft-ietf-bess-evpn-overlay/ IESG discussion can be tracked via https://datatracker.ietf.org/doc/draft-ietf-bess-evpn-overlay/ballot/ No IPR declarations have been submitted directly on this I-D. The document contains these normative downward references.
