1. Connecting IPv6 Multicast Islands over IPv4 MPLS Using IPv6 Provider Edge Routers (6PE)

Publication: IETF Individual Draft

Publication History: 2013-07

Publication URL: https://tools.ietf.org/html/draft-li-idr-mcast-6pe-00

Description:

This document defines a new Network Layer Reachability Information (NLRI), called as the MCAST-6PE NLRI. The MCAST-6PE NLRI is used to interconnect IPv6 C-Multicast islands over a Multiprotocol Label Switching (MPLS)-enabled IPv4 cloud. This approach relies on IPv6 Provider Edge routers (6PE), which can exchange the IPv6 C-Multicast reachability information transparently over the core using the Multiprotocol Border Gateway Protocol (MP-BGP) over IPv4. This document describes the BGP encodings and procedures for exchanging the information elements required by IPv6 Multicast in 6PE. MPLS- based Service Providers may use the 6PE Multicast mechanism to provide IPv6 Multicast service for customers.

2. Global Table Multicast with BGP Multicast VPN (BGP-MVPN) Procedures

Publication: IETF RFC

Publication History: 2015-12

Publication URL: https://tools.ietf.org/html/rfc7716

Description:

RFCs 6513, 6514, and others describe protocols and procedures that a Service Provider (SP) may deploy in order to offer Multicast Virtual Private Network (Multicast VPN or MVPN) service to its customers. Some of these procedures use BGP to distribute VPN-specific multicast routing information across a backbone network. With a small number of relatively minor modifications, the same BGP procedures can also be used to distribute multicast routing information that is not specific to any VPN. Multicast that is outside the context of a VPN is known as “Global Table Multicast”, or sometimes simply as “Internet multicast”. In this document, we describe the modifications that are needed to use the BGP-MVPN procedures for Global Table Multicast.

3. Role-Based State Advertisement for Multicast in MPLS/BGP IP VPNs

Publication: IETF Individual Draft

Publication History: 2015-10

Publication URL: https://tools.ietf.org/html/draft-li-bess-mvpn-role-state-ad-00

Description:

The document defines and uses a new BGP attribute called the “Role Discovery attribute” to advertise the role and corresponding primary/ backup state for Multicast in MPLS/BGP IP VPNs [RFC6514]. The role- based state advertisement can help optimization of process in MPLS/ BGP Multicast VPN.
