specifically related to this document are explained below. specifically related to this document are explained below.
The term "Multicast VPN (MVPN)" [RFC6513] refers to a BGP/MPLS Layer

There are two kinds of PMSIs: "Inclusive PMSI (I-PMSI)" and There are two kinds of PMSIs: "Inclusive PMSI (I-PMSI)" and

Throughout this document, we will use the term "PMSI" to refer both Throughout this document, we will use the term "PMSI" to refer both
"I-PMSI" and "S-PMSI." "I-PMSI" and "S-PMSI."
[RFC6513] describes the following tunnel setup techniques that can be
used to create the P-tunnels that instantiate the PMSIs.
o Protocol Independent Multicast tree
* Sparse Mode (PIM-SM) tree [RFC4601]
* Source Specific Multicast (PIM-SSM) tree [RFC4601]
* Bidirectional Protocol Independent Multicast (BIDIR-PIM) tree

o Resource Reservation Protocol - Traffic Engineering Point-to-
Multipoint (RSVP-TE P2MP) Label Switched Path [RFC4875]
o Ingress Replication through Unicast Tunnels [RFC6513]
A tunnel is identified by its Tunnel Identifier. The length of the
identifier will depend on the setup technique that is used to create
the tunnel.
