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 [L2VPN-VPLS-LDP] or BGP[L2VPN-VPLS-BGP] signalling. This MIB module provides generic management of VPLS services as defined by the IETF L2VPN Working Group. Comments should be made directly to the L2VPN mailing list at l2vpn@ietf.org. 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]. 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 RFC-2119 [BCP14]. 1.1. Changes from version 00 to 01 [NOTE to RFC Editor: this section is to be removed before publication.] L2 VPN Working Group Expires April 2007 [Page 2] draft-nadeau-l2vpn-vpls-mib-02 L2-VPN-MIB Oct 10, 2006 1.1.1. Split the MIB modules into VPLS-GENERIC-DRAFT-01-MIB, VPLS-LDP-DRAFT-01-MIB, VPLS-BGP-DRAFT-01-MIB. The generic MIB Module will contain information common to both LDP and BGP signalled VPLS. 1.1.2. Moved certain objects from vplsConfigTable to vplsStatusTable. 1.1.3. Added new objects to the vplsLdpPwBindTable. 1.1.4. Retained MAC related objects since there is specific reference in [L2VPN-VPLS-LDP] and [L2VPN-VPLS-BGP]. 1.2. Changes from version 00 to 01 [NOTE to RFC Editor: this section is to be removed before publication.] 1.1.1. Added new objects to the vplsConfigTable. 1.1.2. Editorial changes. 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. 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 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]. 4. VPLS MIB Module Architecture The MIB structure for defining a VPLS service is composed from four types of MIB modules. The first type is the VPLS-GENERIC-DRAFT-01-MIB module, which configures general parameters of the VPLS service that are common L2 VPN Working Group Expires April 2007 [Page 3] draft-nadeau-l2vpn-vpls-mib-02 L2-VPN-MIB Oct 10, 2006 to all types of emulated services. The second type is the VPLS-LDP-DRAFT-01-MIB module, which configures VPLS-LDP[L2VPN-VPLS-LDP] specific parameters of the VPLS service. The third type is the VPLS-BGP-DRAFT-01-MIB module, which configures VPLS-BGP[L2VPN-VPLS-BGP] specific parameters of the VPLS service. -- TBD The fourth type of modules are service-specific modules, which are defined in other documents. -------- ----------------- PW Mapping | | | | -----> | PW-MIB |-->|PW-ENET/MPLS-MIB | __________ / | | | | | | / -------- ----------------- | VPLS MIB | / ------------ | |---------->| | ----------- MAC addr. | BRIDGE-MIB | mapping(TBD)| | ------------ 4.1. VPLS-GENERIC-DRAFT-01-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 signalled 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 pseudo wires (defined in [PWE3-PW-MIB]). The pseudo wire may be used as a spoke or a mesh based on the parameters defined L2 VPN Working Group Expires April 2007 [Page 4] draft-nadeau-l2vpn-vpls-mib-02 L2-VPN-MIB Oct 10, 2006 in this table. The agent than creates the rows in the (locally supported) performance tables and reverse mapping tables in VPLS-GENERIC-DRAFT-01-MIB module. 4.2. VPLS-LDP-DRAFT-01-MIB Module Usage An entry in the vplsLdpConfigTable MUST be created by the agent for a VPLS service signalled using LDP. 4.3. VPLS-BGP-DRAFT-01-MIB Module Usage TBD. 4.4. Relations to other MIB modules - The vplsPwBindTable links the VPLS entry to various entries in the [PWE3-PW-MIB] - The association of MAC addresses to VPLS entries is TBD. Presentlyinvestigating BRIDGE-MIB to accomodate the same. - 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 ??? should report 'notPresent'. - Statistics can be gathered from the [PWE3-PW-MIB] - TBD 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.

Security Considerations It is clear that the MIB modules described in this document in association with the PW-STD-MIB [PW-STD-MIB] are potentially useful for monitoring of GMPLS LSRs. 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 operations. These are the tables and objects and their sensitivity/vulnerability: 8. IANA Considerations -- (Note to RFC-Editor:) -- We request that you assign contiguous RFC numbers to the -- IANA is requested to root MIB objects in the MIB module -- contained in this document under the transmission subtree. -- L2 VPN Working Group Expires April 2007 [Page 27] draft-nadeau-l2vpn-vpls-mib-02 L2-VPN-MIB Oct 10, 2006 9.
