The IESG has approved the following document: - 'Multicast in MPLS/BGP IP VPNs ' <draft-ietf-l3vpn-2547bis-mcast-10.txt> as a Proposed Standard This document is the product of the Layer 3 Virtual Private Networks Working Group. The IESG contact persons are Ross Callon and Adrian Farrel. A URL of this Internet-Draft is: http://www.ietf.org/internet-drafts/draft-ietf-l3vpn-2547bis-mcast-10.txt Technical Summary In order for IP multicast traffic within a BGP/MPLS IP VPN (Virtual Private Network) to travel from one VPN site to another, special protocols and procedures must be implemented by the VPN Service Provider. These protocols and procedures are specified in this document (BGP-specific encodings and procedures are specified in the related document draft-ietf-l3vpn-2547bis-mcast-bgp). Working Group Summary The L3VPN WG has been working on multicast for many years, with significant difficulty coming to consensus. This document is put forth with draft-ietf-l3vpn-2547bis-mcast-bgp. Interoperability and default deployment modes are a concern because of the large number of options and features provided in each of these specifications. These concerns are being addressed by draft-ietf-l3vpn-mvpn- considerations, which has been submitted for publication. After much deliberation and consideration in the WG and among relevant stake holders this is the most feasible path forward. Document Quality This document has been extensively reviewed, and has been updated in responsse to many comments including WG and IETF last call and IESG comments. Many of the options described in this document are implemented and widely deployed. The related document draft-ietf- l3vpn-mvpn-considerations is co-authored by experts from multiple service providers based largely on deployment experience. Personnel Danny McPherson is the Document Shepherd for this document. Ross Callon is is the Responsible Area Director. _______________________________________________ IETF-Announce mailing list IETF-Announce@ietf.org https://www.ietf.org/mailman/listinfo/ietf-announce
