The IESG has approved the following document: - 'Multicast VPN Using BIER' (draft-ietf-bier-mvpn-10.txt) as Proposed Standard This document is the product of the Bit Indexed Explicit Replication Working Group. The IESG contact persons are Alvaro Retana, Alia Atlas and Deborah Brungard. A URL of this Internet Draft is: https://datatracker.ietf.org/doc/draft-ietf-bier-mvpn/ Technical Summary The Multicast Virtual Private Network (MVPN) specifications require the use of multicast tunnels ("P-tunnels") that traverse a Service Provider's backbone network. The P-tunnels are used for carrying multicast traffic across the backbone. A variety of P-tunnel types are supported. Bit Index Explicit Replication (BIER) is a new architecture that provides optimal multicast forwarding through a "multicast domain", without requiring intermediate routers to maintain any per-flow state or to engage in an explicit tree-building protocol. This document specifies the protocol and procedures that allow MVPN to use BIER as the method of carrying multicast traffic over an SP backbone network. Working Group Summary The draft has been well received. Although this draft is currently Experimental, the BIER WG is in the middle of rechartering to be Standards Track and it is expected that a Status Update will change this draft in place to be Proposed Standard. Document Quality Based on the discussions at the WG (IETF 98/99) multiple implementations exist and in other cases vendors indicated a strong roadmap commitment.
