[RFC4364] specifies architecture, protocols, and procedures that a Service Provider (SP) can use to provide Virtual Private Network (VPN) service to its customers. In that architecture, one or more Customer Edge (CE) routers attach to a Provider Edge (PE) router. Each CE router belongs to a single VPN, but CE routers from several VPNs may attach to the same PE router. In addition, CEs from the same VPN may attach to different PEs. BGP is used to carry VPN- specific information among the PEs. Each PE router maintains a separate Virtual Routing and Forwarding table (VRF) for each VPN to which it is attached.

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