The IESG has received a request from the Layer 3 Virtual Private Networks WG (l3vpn) to consider the following document: - 'Multipoint Label Distribution Protocol In-Band Signaling in a VRF Context' <draft-ietf-l3vpn-mldp-vrf-in-band-signaling-03.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 2014-02-12. 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 An IP Multicast Distribution Tree (MDT) may traverse both label switching (i.e. - Multi-Protocol Label Switching, or MPLS) and non- label switching regions of a network. Typically the MDT begins and ends in non-MPLS regions, but travels through an MPLS region. In such cases, it can be useful to begin building the MDT as a pure IP MDT, then convert it to an MPLS Multipoint Label Switched Path (MP- LSP) when it enters an MPLS-enabled region, and then convert it back to a pure IP MDT when it enters a non-MPLS-enabled region. Other documents specify the procedures for building such a hybrid MDT, using Protocol Independent Multicast (PIM) in the non-MPLS region of the network, and using Multipoint Extensions to Label Distribution Protocol (mLDP) in the MPLS region. This document extends those procedures to handle the case where the link connecting the two regions is a "Virtual Routing and Forwarding Table" (VRF) link, as defined in the "BGP IP/MPLS VPN" specifications. However, this document is primarily aimed at particular use cases where VRFs are used to support multicast applications other than Multicast VPN.
