       BGP/MPLS Layer 3 VPN Multicast Management Information Base

Abstract

   This memo defines a portion of the Management Information Base (MIB)
   for use with network management protocols in the Internet community.
   In particular, it describes managed objects to configure and/or
   monitor Multicast communication over IP Virtual Private Networks
   (VPNs) supported by the Multiprotocol Label Switching/Border Gateway
   Protocol (MPLS/BGP) on a Provider Edge (PE) router.

1.  Introduction

   [RFC6513], [RFC6514], and [RFC6625] specify procedures for supporting
   multicast in Multiprotocol Label Switching/Border Gateway Protocol
   (MPLS/BGP) Layer 3 (IP) Virtual Private Networks (VPNs).  Throughout
   this document, we will use the term "MVPN" (for "multicast VPN")
   [RFC6513] to refer to a BGP/MPLS IP VPN that supports multicast.

   Provider Edge (PE) routers that attach to a particular MVPN exchange
   customer multicast (C-multicast) routing information with neighboring
   PEs.  In [RFC6513], two basic methods for exchanging C-multicast
   routing information are defined: (1) Protocol Independent Multicast
   (PIM) [RFC7761] and (2) BGP.

   In the rest of this document, we will use the term "PIM-MVPN" to
   refer to the case where PIM is used for exchanging C-multicast
   routing information and "BGP-MVPN" to refer to the case where BGP is
   used for exchanging C-multicast routing information.

   This document describes managed objects to configure and/or monitor
   MVPNs.  Most of the managed objects are common to both PIM-MVPN and
   BGP-MVPN, and some managed objects are BGP-MVPN specific.

1.1.  Terminology

   This document adopts the definitions, abbreviations, and mechanisms
   described in [RFC4364], [RFC6513], and [RFC6514].  Familiarity with
   multicast, MPLS, Layer 3 (L3) VPN, and MVPN concepts and/or
   mechanisms is assumed.  Some terms specifically related to this
   document are explained below.

RFC 8503                  L3 VPN Multicast MIB             December 2018

   An MVPN can be realized by using various kinds of transport
   mechanisms for forwarding a packet to all or a subset of PEs across
   service provider networks.  Such transport mechanisms are referred to
   as provider tunnels (P-tunnels).
