The IESG has received a request from the BGP Enabled ServiceS WG (bess) to consider the following document: - 'Interconnect Solution for EVPN Overlay networks' <draft-ietf-bess-dci-evpn-overlay-06.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 2018-02-09. 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 describes how Network Virtualization Overlays (NVO) can be connected to a Wide Area Network (WAN) in order to extend the layer-2 connectivity required for some tenants. The solution analyzes the interaction between NVO networks running Ethernet Virtual Private Networks (EVPN) and other L2VPN technologies used in the WAN, such as Virtual Private LAN Services (VPLS), VPLS extensions for Provider Backbone Bridging (PBB-VPLS), EVPN or PBB-EVPN. It also describes how the existing Technical Specifications apply to the Interconnection and extends the EVPN procedures needed in some cases. In particular, this document describes how EVPN routes are processed on Gateways (GWs) that interconnect EVPN-Overlay and EVPN-MPLS networks, as well as the Interconnect Ethernet Segment (I-ES) to provide multi-homing, and the use of the Unknown MAC route to avoid MAC scale issues on Data Center Network Virtualization Edge (NVE) devices.
