The IESG has approved the following document: - 'Requirements for Metro Ethernet Forum (MEF) Ethernet-Tree (E-Tree) Support in L2VPN' (draft-ietf-l2vpn-etree-reqt-05.txt) as Informational RFC This document is the product of the Layer 2 Virtual Private Networks Working Group. The IESG contact persons are Stewart Bryant and Adrian Farrel. A URL of this Internet Draft is: http://datatracker.ietf.org/doc/draft-ietf-l2vpn-etree-reqt/ Technical Summary The draft describes L2VPN requirements for a Metro Ethernet Forum services, known as the E-Tree services. An E-Tree services is defined by a one or more roots and one or more leaves. Roots can send traffic to other roots and leaves and received traffic from other roots and leaves. Leaves can only receive traffic from roots and send traffic to roots. E-Tree requirements are not satisfied by existing L2VPN solution. Working Group Summary This document is an L2VPN Working Group document. It has gone through a few iterations that addressed few comments received from the Working group and comments received the WG chairs. The draft was generalized from VPLS to L2VPN to allow for a potentially wider solution set, namely including E-VPN. The draft also has a substantial number of authors and contributors from the Working Group. The draft had good support when it was adopted as a WG draft. However when the draft was last called, no feedback was received, maybe due to the nature of the draft and the fact that there are several authors and contributors to the draft already from the WG. Upon last review by the WG chairs of the draft and feedback to the authors, the authors updated the draft addressing the chairs' comments, mainly modifying the author list and moving some to contributors, performing few edits, and removing the appendix on use cases as it did not include requirements. The use cases are part of another framework draft. Document Quality The document has good quality. It is clear on the technical content and written with good English and layout. There may be an edit or so needed that may be taken up during the RFC edits. Personnel Nabil Bitar (nabil.n.bitar@verizon.com) is the Document Shepherd.
