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 a MIB module that can be used
   to manage VPLS (Virtual Private LAN Services) for transmission over
   a packet Switched Network (PSN) using LDP [RFC4762] or BGP [RFC4761]
   signalling. 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 as defined 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 re-described 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 a set of MIB modules that are compliant to the SMIv2,
   which is described in STD 58 [RFC2578][RFC2579][RFC2580].

4. VPLS MIB Module Architecture

   The MIB structure for defining a VPLS service is composed from
   three MIB modules.

   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.

                          --------

   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 a VPLS service.
    This table holds generic parameters which 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) The operator creates a row in the vplsConfigTable when
        configuring the node for a new service. This mode MUST be
        supported by the agent, and MUST be used when creating a
        manually assigned VPLS service.

    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.

     An entry in the vplsPwBindTable MUST exist for a 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.

     An entry in the vplsBgpAdConfigTable MUST exist if
     Auto-discovery has been enabled on this service. This table
     stores the information required for auto-discovery.

     An entry in the vplsBgpRteTargetTable MUST exist if auto-discovery
     has been configured on this service. One service can import
     and export multiple Route Targets.

     The agent then creates the rows in the (locally supported)
     performance tables and reverse mapping tables in
     VPLS-GENERIC-MIB module.

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 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 between 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 Pseudowire performance
       tables in [RFC5601]

5. Example of the VPLS MIB modules usage

    In this section we provide an example of using the MIB objects
    described in section 7 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 VPLS service (VPLS-A) is setup using LDP for
    signaling the pseudowire. The binding between the Vpls 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),
   }

   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
   }

            If the operator needs to change one of the values
            for an active row the vplsConfigRowStatus should be
            first changed to notInService(2), the objects may
            then be changed, and finally the vplsConfigRowStatus
            should be changed to active(1) in order to re-initiate

           "A row in this table represents LDP specific information

           It is indexed by vplsConfigIndex, which uniquely

           A row is automatically created when a VPLS service is
           configured using LDP signaling.

           changed when vplsRowStatus is in the active(1)
           state. Changes are allowed when the vplsRowStatus
           is in notInService(2) or notReady(3) states only.
           If the operator needs to change one of the values
           for an active row the vplsConfigRowStatus should be
           first changed to notInService(2), the objects may

           should be changed to active(1) in order to

7. Security Considerations

   It is clear that the MIB modules described in this document in
   association with the PW-STD-MIB [RFC5601] are potentially
   useful for monitoring of VPLS capable LERs. These MIB modules can
   also be used for configuration of certain objects, and anything that
   can be configured can be incorrectly configured, with potentially
   disastrous results.

   There are a number of management objects defined in these MIB
   modules 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 operation.

8. IANA Considerations

-- (Note to RFC-Editor:)
--   IANA is requested to root the MIB modules
--   contained in this document under the transmission subtree.
