1.  Introduction

   In BGP/MPLS Virtual Private Networks (VPNs), Border Gateway Protocol
   (BGP) is used for distributing routes and MultiProtocol Label
   Switching (MPLS) is used for forwarding packets accross service
   provider networks.

   The procedures for supporting multicast in BGP/MPLS Layer 3 (L3) VPN
   are specified in [RFC6513].  The procedures for supporting multicast
   in BGP/MPLS Layer 2 (L2) VPN are specified in [RFC7117].  Throughout
   this document, we will use the term "L2L3VpnMCast network" to mean
   BGP/MPLS L2 and L3 VPN that support multicast.

   L2L3VpnMCast networks use various transport mechanisms for forwarding
   a packet to all or a subset of Provider Edge routers (PEs) across
   service provider networks.  These transport mechanisms are abstracted
   as provider tunnels (P-tunnels).  The type of a P-tunnel indicates
   the type of the tunneling technology used to establish the P-tunnel.
   The syntax and semantics of a Tunnel identifier is determined by the
   corresponding P-tunnel type [RFC6514].  P-tunnel type and P-tunnel
   identifier together identify a P-tunnel.

   A BGP attribute that specifies information of a P-tunnel is called
   Provider Multicast Service Interface (PMSI) tunnel attribute.  The
   PMSI tunnel attribute is advertised/received by PEs in BGP auto-
   discovery (A-D) routes.  [RFC6514] defines the format of a PMSI
   tunnel attribute.  P-tunnel type and the P-tunnel identifier are
   included in the corresponding PMSI tunnel attribute.

Internet-Draft             L2L3-VPN-MCAST MIB              February 2018


   This document describes textual conventions (TCs) and common managed
   objects (MOs) which will be used by other Management Information Base
   (MIB) modules for monitoring and/or configuring L2L3VpnMCast
   networks.

   This document defines two TCs to represent

   (a) the type of a P-tunnel and
   (b) the identifier of a P-tunnel

   respectively.

   The document also defines MOs that will provide the information
   contained in a PMSI tunnel attribute and corresponding P-tunnel
   information.

1.1.  Terminology

   This document adopts the definitions, acronyms and mechanisms
   described in [RFC6513] [RFC6514] [RFC7117] and other documents that
   they refer to.  Familiarity with Multicast, MPLS, Layer 3 VPN,
   Multicast VPN concepts and/or mechanisms is assumed.  Some terms
   specifically related to this document are explained below.

   "Provider Multicast Service Interface (PMSI)" [RFC6513] is a
   conceptual interface instantiated by a P-tunnel, a transport
   mechanism used to deliver multicast traffic.  A PE uses it 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 is a PMSI that
   enables a PE attached to a particular Multicast VPN to transmit a
   message to all PEs in the same VPN.  An S-PMSI is a PMSI that enables
   a PE attached to a particular Multicast VPN to transmit a message to
   some of the PEs in the same VPN.

   Throughout this document, we will use the term "PMSI" to refer both
   "I-PMSI" and "S-PMSI."

   The key words "MUST", "SHOULD", "RECOMMENDED", and "MAY" in this
   document are to be interpreted as described in [RFC2119].

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].

Internet-Draft             L2L3-VPN-MCAST MIB              February 2018


   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.  Summary of MIB Modules

   This document defines two MIB modules: L2L3-VPN-MCAST-TC-MIB and
   L2L3-VPN-MCAST-MIB.

   o  L2L3-VPN-MCAST-TC-MIB contains two Textual Conventions:
      L2L3VpnMcastProviderTunnelType and L2L3VpnMcastProviderTunnelId.
      L2L3VpnMcastProviderTunnelType provides an enumeration of the
      P-tunnel types.  L2L3VpnMcastProviderTunnelId represents an
      identifier of a P-tunnel.

   o  L2L3-VPN-MCAST-MIB defines a table
      l2L3VpnMcastPmsiTunnelAttributeTable.  An entry in this table
      corresponds to the attribute information of a specific P-tunnel on
      a PE router.  Entries in this table will be used by other MIB
      modules for monitoring and/or configuring L2L3VpnMCast network.
      The table index uniquely identifies a P-tunnel.  It is composed of
      a type and indentifier of a P-tunnel.  The table may also be used
      in conjunction with other MIBs, such as MPLS Traffic Engineering
      MIB (MPLS-TE-STD-MIB) [RFC3812], to obtain further information
      about a P-tunnel.  It may also be used in conjunction with the
      Interfaces Group MIB (IF-MIB) [RFC2863] to obtain further
      information about the interface corresponding to a P-tunnel.

5.  Security Considerations

   There are no management objects defined in these MIB modules that
   have a MAX-ACCESS clause of read-write and/or read-create.  So, if
   this MIB module is implemented correctly, then there is no risk that
   an intruder can alter or create any management objects of this MIB
   module via direct SNMP SET operations.

   Some of the readable objects in these MIB modules (i.e., objects with
   a MAX-ACCESS other than not-accessible) may be considered sensitive
   or vulnerable in some network environments.  It is thus important to



Zhang & Tsunoda         Expires September 1, 2018              [Page 15]


Internet-Draft             L2L3-VPN-MCAST MIB              February 2018


   control even GET and/or NOTIFY access to these objects and possibly
   to even encrypt the values of these objects when sending them over
   the network via SNMP.  These are the tables and objects and their
   sensitivity/vulnerability:

   o  the l2L3VpnMcastPmsiTunnelAttributeTable collectively shows the
      P-tunnel network topology and its performance characteristics.
      For instance, l2L3VpnMcastPmsiTunnelAttributeId in this table will
      contain the identifier that uniquely identifies a P-tunnel.  This
      identifier may be composed of source and multicast group IP
      addresses.  l2L3VpnMcastPmsiTunnelPointer and
      l2L3VpnMcastPmsiTunnelIf will point to the corresponding entries
      in other tables containing configuration and/or performance
      information of a P-tunnel and its interface.  If an Administrator
      does not want to reveal this information, then these objects
      should be considered sensitive/vulnerable.

   SNMP versions prior to SNMPv3 did not include adequate security.
   Even if the network itself is secure (for example by using IPsec),
   there is no control as to who on the secure network is allowed to
   access and GET/SET (read/change/create/delete) the objects in this
   MIB module.

   Implementations SHOULD provide the security features described by the
   SNMPv3 framework (see [RFC3410]), and implementations claiming
   compliance to the SNMPv3 standard MUST include full support for
   authentication and privacy via the User-based Security Model (USM)
   [RFC3414] with the AES cipher algorithm [RFC3826].  Implementations
   MAY also provide support for the Transport Security Model (TSM)
   [RFC5591] in combination with a secure transport such as SSH
   [RFC5592] or TLS/DTLS [RFC6353].

   Further, deployment of SNMP versions prior to SNMPv3 is NOT
   RECOMMENDED.  Instead, it is RECOMMENDED to deploy SNMPv3 and to
   enable cryptographic security.  It is then a customer/operator
   responsibility to ensure that the SNMP entity giving access to an
   instance of this MIB module is properly configured to give access to
   the objects only to those principals (users) that have legitimate
   rights to indeed GET or SET (change/create/delete) them.

6.  IANA Considerations

   The MIB module in this document uses the following IANA-assigned
   OBJECT IDENTIFIER values recorded in the SMI Numbers registry:







Zhang & Tsunoda         Expires September 1, 2018              [Page 16]


Internet-Draft             L2L3-VPN-MCAST MIB              February 2018


   Descriptor        OBJECT IDENTIFIER value
   ----------        -----------------------
   l2L3VpnMcastTCMIB  { mib-2 AAA }
   l2L3VpnMcastMIB    { mib-2 BBB }

   Editor's Note (to be removed prior to publication): the IANA is
   requested to assign a value for "AAA" and "BBB" under the 'mib-2'
   subtree and to record the assignment in the SMI Numbers registry.
   When the assignment has been made, the RFC Editor is asked to replace
   "AAA" and "BBB" (here and in the MIB module) with the assigned value
   and to remove this note.
