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   RFC8503 - 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   RFC8503 - 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   RFC8503 - 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].
