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.

Top      ToC       Page 3 
   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).

   A Provider Multicast Service Interface (PMSI) [RFC6513] is a
   conceptual interface instantiated by a P-tunnel.  A PE uses a PMSI to
   send customer multicast traffic to all or some PEs in the same VPN.

   There are two kinds of PMSIs: Inclusive PMSI (I-PMSI) and Selective
   PMSI (S-PMSI) [RFC6513].  An I-PMSI enables a PE attached to a
   particular MVPN to transmit a message to all PEs in the same MVPN.
   An S-PMSI enables a PE to transmit a message to a selected set of PEs
   in the same MVPN.

   As described in [RFC4382], each PE maintains one default forwarding
   table and zero or more Virtual Routing and Forwarding (VRF) tables.
   Throughout this document, we will use the term "MVRF" (for "multicast
   VRF") to refer to a VRF that contains multicast routing information.

   The key words "MUST", "MUST NOT", "REQUIRED", "SHALL", "SHALL NOT",
   "SHOULD", "SHOULD NOT", "RECOMMENDED", "NOT RECOMMENDED", "MAY", and
   "OPTIONAL" in this document are to be interpreted as described in
   BCP 14 [RFC2119] [RFC8174] when, and only when, they appear in all
   capitals, as shown here.

2.  The Internet-Standard Management Framework

   For a detailed overview of the documents that describe the current
   Internet-Standard Management Framework, please refer to section 7 of
   RFC 3410 [RFC3410].

   Managed objects are accessed via a virtual information store, termed
   the Management Information Base or MIB.  MIB objects are generally
   accessed through the Simple Network Management Protocol (SNMP).
   Objects in the MIB are defined using the mechanisms defined in the
   Structure of Management Information (SMI).  This memo specifies a MIB
   module that is compliant to the SMIv2, which is described in STD 58,
   RFC 2578 [RFC2578], STD 58, RFC 2579 [RFC2579] and STD 58, RFC 2580
   [RFC2580].

3.  BGP-MPLS-LAYER3-VPN-MULTICAST-MIB

   This document defines BGP-MPLS-LAYER3-VPN-MULTICAST-MIB, a MIB module
   for monitoring and/or configuring MVPNs on PEs.  This MIB module will
   be used in conjunction with MPLS-L3VPN-STD-MIB [RFC4382] and IPMCAST-
   MIB [RFC5132].

Top      ToC       Page 4 
3.1.  Summary of the MIB Module

   BGP-MPLS-LAYER3-VPN-MULTICAST-MIB provides the following
   functionalities.

   o  Monitoring attributes of MVPNs on a PE

   o  Configuring timers and thresholds related to an MVPN on a PE

   o  Notifying creation, deletion, and modification of MVRFs on a PE

   o  Monitoring PMSI attributes

   o  Monitoring statistics of advertisements exchanged by a PE

   o  Monitoring routing information for multicast destinations

   o  Monitoring next hops for each multicast destination

   To provide these functionalities, BGP-MPLS-LAYER3-VPN-MULTICAST-MIB
   defines the following tables.

   o  mvpnGenericTable

      This table contains generic information about MVPNs on a PE.  Each
      entry in this table represents an instance of an MVPN on a PE and
      contains generic information related to the MVPN.  For each entry
      in this table, there MUST be a corresponding VRF in MPLS-L3VPN-
      STD-MIB [RFC4382].

   o  mvpnBgpTable

      This table contains information specific to BGP-MVPNs.  Each BGP-
      MVPN on a PE will have an entry in this table.

   o  mvpnPmsiTable

      This table contains managed objects representing attribute
      information that is common to I-PMSIs and S-PMSIs on a PE.

   o  mvpnSpmsiTable

      This table contains managed objects representing attribute
      information specific to S-PMSIs.  An S-PMSI represented in this
      table will have a corresponding entry in mvpnPmsiTable.

Top      ToC       Page 5 
   o  mvpnAdvtStatsTable

      This table contains statistics pertaining to I-PMSI and S-PMSI
      advertisements sent/received.

   o  mvpnMrouteTable

      This table contains multicast routing information in MVRFs on a
      PE.

   o  mvpnMrouteNextHopTable

      This table contains information on the next hops for routing IP
      multicast datagrams in MVPNs on a PE.

3.2.  MIB Module Definitions

   This MIB module makes reference to the following documents:
   [RFC2003], [RFC2784], [RFC2863], [RFC3032], [RFC4001], and [RFC8502].
