1.  Introduction

   This memo defines a portion of the Management Information Base (MIB)
   for use with network management protocols in the Internet community.
   In particular, it defines three MIB modules that can be used to
   manage VPLS (Virtual Private LAN Service) for transmission over a
   Packet Switched Network (PSN) using LDP [RFC4762] or BGP [RFC4761]
   signaling.  This MIB module provides generic management of VPLS
   services as defined by the IETF L2VPN Working Group.  Additional MIB
   modules are also defined for management of LDP VPLS and BGP VPLS
   services by the IETF L2VPN Working Group.

2.  Terminology

   This document adopts the definitions, acronyms, and mechanisms
   described in [RFC3985].  Unless otherwise stated, the mechanisms of
   [RFC3985] apply and will not be described again here.

2.1.  Conventions Used in This Document

   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 [RFC2119].

3.  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 MIB
   modules that are compliant to the SMIv2, which is described in STD
   58, RFC 2578 [RFC2578], STD 58, RFC 2579 [RFC2579] and STD 58, RFC
   2580 [RFC2580].

4.  VPLS MIB Module Architecture

   The MIB structure for defining a VPLS service is composed from three
   MIB modules.  (They are referred to as "VPLS MIB" in the figure
   below.)

   The first is the VPLS-GENERIC-MIB module, which configures general
   parameters of the VPLS service that are common to all types of VPLS
   services.

   The second is the VPLS-LDP-MIB module, which configures VPLS-LDP
   [RFC4762] specific parameters of the VPLS service.

   The third is the VPLS-BGP-MIB module, which configures VPLS-BGP
   [RFC4761] specific parameters of the VPLS service.

   The arrows in Figure 1 indicate whether we can map data from one
   module into another.

                          Figure 1

   Additionally, service-specific modules may be defined in other
   documents.

4.1.  VPLS-GENERIC-MIB Module Usage

   An entry in the vplsConfigTable MUST exist for every VPLS service.
   This table holds generic parameters that apply to a VPLS service
   which can be signaled via LDP or BGP.

   A conceptual row can be created in the vplsConfigTable in one of the
   following ways:

   1) A Network Management System (NMS) creates a row in the
      vplsConfigTable using Simple Network Management Protocol (SNMP)
      Set requests, which causes the node to create and start a new VPLS
      service.  The agent MUST support the creation of VPLS services in
      this way.

   2) The agent MAY create a row in the vplsConfigTable automatically
      due to some auto discovery application, or based on configuration
      that is done through non-SNMP applications.  This mode is
      OPTIONAL.

   At least one entry in the vplsPwBindTable MUST exist for each VPLS
   service.

   This Binding table links one VPLS service with one or many
   pseudowires (defined in [RFC5601]).  Each pseudowire may be used as a
   spoke or as part of a mesh based on the parameters defined in this
   table.

   For each VPLS service, an entry in the vplsBgpAdConfigTable MUST
   exist if Auto-discovery has been enabled for that service.  This
   table stores the information required for auto-discovery.

RFC 7257            VPLS Management Information Base           July 2014


   For each VPLS service, at least one entry in the
   vplsBgpRteTargetTable MUST exist if auto-discovery has been
   configured for that service.  One service can import and export
   multiple Route Targets.

4.2.  VPLS-LDP-MIB Module Usage

   An entry in the vplsLdpConfigTable MUST be created by the agent for a
   VPLS service signaled using LDP.

4.3.  VPLS-BGP-MIB Module Usage

   An entry in the vplsBgpConfigTable MUST be created by the agent for a
   VPLS service signaled using BGP.

4.4.  Relations to Other MIB Modules

   - The vplsPwBindTable links the VPLS entry to the pwTable in
     [RFC5601].

   - The association of Media Access Control (MAC) addresses to VPLS
     entries is possible by adding a turnstile function to interpret the
     entries in [SNMP-CONTEXT-MAP-MIB].  In [SNMP-CONTEXT-MAP-MIB],
     there is a mapping from the vacmContextName [RFC3415] to
     dot1dBasePort [RFC4188] and vplsConfigIndex.  This mapping can be
     used to map the vplsConfigIndex to a dot1dBasePort in the BRIDGE-
     MIB.  This resulting value of dot1dBasePort can be used to access
     corresponding MAC addresses that belong to a particular
     vplsConfigIndex.

   - Unless all the necessary entries in the applicable tables have been
     created and all the parameters have been consistently configured in
     those tables, signaling cannot be performed from the local node,
     and the vplsConfigRowStatus should report 'notReady'.

   - Statistics can be gathered from the PW Performance tables in
     [RFC5601].

5.  Example of the VPLS MIB Modules Usage

   In this section, we provide an example of the use of the MIB objects
   described in Section 6 to set up a VPLS service over MPLS.  While
   this example is not meant to illustrate every permutation of the MIB,
   it is intended as an aid to understanding some of the key concepts.
   It is meant to be read after going through the MIB itself.

   In this example, a VPLS service (VPLS-A) is set up using LDP for
   signaling the pseudowire.  The Binding between the VPLS service and
   the pseudowire is reflected in the VplsPwBindTable.  The pseudowire
   configuration is defined in RFC 5601.

   In the VPLS-GENERIC-MIB module:

   Row in vplsConfigTable:
   {
        vplsConfigIndex                         10,
        vplsConfigName                          "VPLS-A"
        vplsConfigAdminStatus                   1(up),
        vplsConfigMacLearning                   1(true),
        vplsConfigDiscardUnknownDest            2(false),
        vplsConfigMacAging                      1(true),
        vplsConfigVpnId                         "100:10"
        vplsConfigRowStatus                     1(active)
   }

   Row in vplsStatusTable:
   {
        vplsStatusOperStatus                    1(up),
        vplsStatusPeerCount                     1
   }

   Row in VplsPwBindTable :
   {
              vplsPwBindConfigType             manual,
              vplsPwBindType                   spoke,
              vplsPwBindRowStatus              1(active),
              vplsPwBindStorageType            volatile
   }

   In the VPLS-LDP-MIB module:

   Row in vplsLdpConfigTable:
   {
         vplsLdpConfigMacAddrWithdraw            1(true),

   }

   Row in vplsLdpPwBindTable:
   {
         vplsLdpPwBindType                 1(mesh),
         vplsLdpPwBindMacAddressLimit      100
   }

7.  Security Considerations

   There are a number of management objects defined in this MIB module
   with a MAX-ACCESS clause of read-write and/or read-create.  Such
   objects may be considered sensitive or vulnerable in some network
   environments.  The support for SET operations in a non-secure
   environment without proper protection can have a negative effect on
   network operations.  These are the tables and their
   sensitivity/vulnerability:

   o  vplsConfigTable:
   o  vplsPwBindTable:
   o  vplsBgpADConfigTable:
   o  vplsBgpRteTargetTable:
   o  vplsLdpPwBindTable:
   o  vplsLdpConfigTable:
   o  vplsBgpConfigTable:
   o  vplsBgpVETable:

      The tables listed above contain read-create/read-write objects
      that can be used to configure or modify a LDP/BGP VPLS service.
      Any improper configuration or modification of objects in these
      tables can disrupt VPLS services.

      The use of stronger mechanisms such as SNMPv3 security should be
      considered where possible for configuring these objects.
      Specifically, SNMPv3 View-based Access Control Model (VACM) and
      User-based Security Model (USM) MUST be used with any v3 agent
      that provides SET access to these tables.

   o  vplsNotificationMaxRate
      Setting this object to a very high value can cause a notification
      storm that may disrupt network service.

   Most 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 readable objects are contained in the
   following tables:

   o vplsConfigTable
   o vplsStatusTable
   o vplsPwBindTable
   o vplsBgpADConfigTable
   o vplsBgpRteTargetTable
   o vplsLdpPwBindTable



Nadeau, et al.               Standards Track                   [Page 44]

RFC 7257            VPLS Management Information Base           July 2014


   o vplsLdpConfigTable
   o vplsBgpConfigTable
   o vplsBgpVETable
   o vplsBgpPwBindTable

   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.

8.  IANA Considerations

   The MIB modules in this document use the following IANA-assigned
   OBJECT IDENTIFIER values recorded in the SMI Numbers registry.

8.1.  IANA Considerations for VPLS-GENERIC-MIB

   The IANA has assigned { transmission 274 } to the VPLS-GENERIC-MIB
   module specified in this document.

8.2.  IANA Considerations for VPLS-LDP-MIB

   The IANA has assigned { transmission 275 } to the VPLS-LDP-MIB module
   specified in this document.

8.3.  IANA Considerations for VPLS-BGP-MIB

   The IANA has assigned { transmission 276 } to the VPLS-BGP-MIB module
   specified in this document.
