Internet-Draft                  mLDP MIB                    January 2014


1.  Introduction

   This memo defines a portion of the Management Information Base (MIB)
   for use with network management protocols.  In particular it defines
   objects for managing multicast LDP point-to-multipoint (P2MP) and
   multipoint-to-multipoint (MP2MP) Label Switched Paths.  The MIB
   module defined in this document is extension of LDP MIB defined in
   RFC3815 which supports only for LDP point-to-point LSPs.

   The RFC3815 describes only unicast Managed objects for the Label
   distribution protocol.  The RFC6388 describes LDP protocol
   extenstions for the point to multipoint and multipoint to multipoint
   LSPs.  The RFC 6826 describes multicast LDP inband signalling for
   P2MP and MP2MP LSPs.

   This document defines a MIB module for managing and controlling mLDP
   P2MP and MP2MP LSPs.  It builds on the objects and tables defined in
   [RFC3815] for mLDP MIB.

2.  The Internet-Standard Management Framework

   [[anchor3: The title and text for this section has been copied from
   the official boilerplate, and should not be modified unless the
   official boilerplate text from the OPS Area web site has changed.
   See RFC4818 section 3.1 for a discussion of the boilerplate
   section.]]

   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.  Conventions

   The key words "MUST", "MUST NOT", "REQUIRED", "SHALL", "SHALL NOT",
   "SHOULD", "SHOULD NOT", "RECOMMENDED", "MAY", and "OPTIONAL" in this
   document are to be interpreted as described in BCP 14, RFC 2119
   [RFC2119].

Internet-Draft                  mLDP MIB                    January 2014


4.  Overview

   This document focusses on the management of following multicast LDP
   (mLDP) features, which were defined after unicast LDP [RFC5036].

      RFC6388: Label Distribution Protocol Extensions for Point-to-
      Multipoint and Multipoint-to-Multipoint Label Switched Paths.

      RFC6826: Multipoint LDP In-Band Signaling for Point-to-Multipoint
      and Multipoint-to-Multipoint Label Switched Paths.

      RFC7060: Using LDP Multipoint Extensions on Targeted LDP Sessions.

      [MoFRR] Multicast only Fast Re-Route draft-ietf-rtgwg-mofrr-03 .

      [MLDP_NODE_PROT] mLDP Node Protection.

   For all the above features, the mLDP MIB needs to include the
   following information:

      - Session Capability (P2MP, MP2MP) information: configured
      capability, negotiated capability.

      - mLDP FECs: include opaque information (Generic LSP Identifier,
      source and group address) and MoFRR enable.

      - Primary and backup upstream session when mLDP MoFRR enabled.

      - Active and inactive upstream session for make before break.

      - mLDP Traffic stats per mLDP Fec: The traffic stats for mLDP fec.

      - mLDP Traffic stats per per Interface: The mLDP traffic stats per
      Interface.

      - Traps when mLDP Fec LSP up, down.

5.  Future Considerations

   Any new opaque TLVs added for any other mLDP fetures, the opaque
   value object in the mplsMldpFecTable need to be enhanced accordingly.

6.  Structure of the MIB Module

   This section describes the structure of the mLDP MIB.  In this MIB
   MPLS-MLDP-STD-MIB, scalar objects, table objects and notifications
   are defined.  Following section describes in details about each
   object.

   P2P Fec. In this MIB, the following notification added to support
   mLDP features.

   The mplsMldpFecUp and mplsMldpFecDown notifications are generated
   when mLDP FEC changes the state to UP and Down.

10.  Relationship to Other MIB Modules

   This section describes relationships between MIB tables defined in
   this document as part of MPLS-MLDP-STD-MIB, and the tables defined in
   MPLS-LDP-STD-MIB [RFC3815] and MPLS-LSR-STD-MIB [RFC3813].

   The Figure 1 shows the diagrammatic representation of the
   relationship between MPLS-MLDP-STD-MIB, MPLS-LDP-STD-MIB and MPLS-
   LSR-STD-MIB.  An arrow in the Figure shows that the MIB table pointed
   from contains a reference to the MIB table pointed to.

12.  Security Considerations

   This MIB module is useful for the configuration of certain objects
   and monitoring of mLDP LSPs.

   There are no management objects defined in this MIB module 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 this MIB module (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
   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  mplsMldpFecTable




Kishore Tiruveedhula, et al.  Expires August 4, 2014           [Page 36]


Internet-Draft                  mLDP MIB                    January 2014


   o  mplsLdpPeerCapabilityTable

   o  mplsMldpSessionStatsTable

   o  mplsMldpFecBranchStatsTable

   o  mplsMldpFecUpstreamSessTable

   o  mplsMldpInterfaceStatsTable

   o  mplsMldpNumFecsConfigured

   o  mplsMldpNumFecsActive

   o  mplsMldpMbbTime

   Above listed tables and objects show information about the mLDP LSPs,
   its route through the network, and its traffic statistics.  Knowledge
   of this information could be used to compromise the network, or
   simply to breach confidentiality.  If an Administrator does not want
   to reveal this information, these tables and 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.
