Next-generation multicast VPN

Multiprotocol BGP (MBGP) next-generation multicast VPNs with the following types of provider tunnels:

• Ingress replication
• RSVP-Traffic Engineering (RSVP-TE) point-to-multipoint (P2MP)
• Multipoint LDP P2MP

A P2MP is a Multiprotocol Label Switching (MPLS) label-switched path (LSP) with a single source and multiple destinations. By taking advantage of MPLS packet replication capability of the network, P2MP LSPs avoid unnecessary packet replication at the ingress router. Packet replication takes place only when packets are forwarded to two or more different destinations requiring different network paths.
