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]. Kishore Tiruveedhula, et al. Expires August 4, 2014 [Page 4] 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. Kishore Tiruveedhula, et al. Expires August 4, 2014 [Page 5] Internet-Draft mLDP MIB January 2014 6.1. Summary of mLDP Scalar Objects New scalar objects mplsMldpP2mpCapable and mplsMldpMp2mpCapable are defined to provide the mLDP capabilities of P2MP, MP2MP support. New scalar objects mplsMldpMbbCapable and mplsMldpMbbTime are defined to provide MBB capability information. New scalar object mplsMldpNumFecsConfigured which will give the total number of mLDP FECs configured on the LSR. Another New scalar object mplsMldpNumFecsActive, which will give the total number of active mLDP FECs. New scalar objects mplsMldpPlrCapable, mplsMldpMptCapable, mplsMldpProtLsrCapable and mplsMldpNodeProtCapable are defined to provide mLDP node protection capabilities. 6.2. Summary of mLDP Table Objects mplsLdpPeerCapabilityTable to include peer capability information. mplsMldpSessionStatsTable : This table contains the number of mLDP FECs received and advertised to particular LDP session. mplsMldpFecTable: This table is similar to point to point mplsLdpFecTable and will have mLDP specific Fec information. mplsMldpFecBranchStatsTable : This table contains the traffic statistics for the given mLDP FECs on particular interface. mplsMldpFecUpstreamSessTable : Includes the upstream session info for the particular mLDP Fec and also includes the primary or backup upstream session, that may be used for mLDP MoFRR. mplsMldpInterfaceStatsTable : This table contains the traffic statistics for all mLDP related FECs. 7. mLDP Scalar Objects There are ten scalars, listed below are defined for this MIB module. 7.1. mplsMldpP2mpCapable The mplsMldpP2mpCapable scalar object denotes whether the LSR is capable of supporting multicast LDP with Point-to-Multipoint capability. Kishore Tiruveedhula, et al. Expires August 4, 2014 [Page 6] Internet-Draft mLDP MIB January 2014 7.2. mplsMldpMp2mpCapable The mplsMldpMp2mpCapable scalar object denotes whether the LSR is capable of supporting multicast LDP with Multipoint-to-Multipoint LSPs. 7.3. mplsMldpMbbCapable The mplsMldpMbbCapable scalar object denotes whether the LSR is capable of supporting multicast LDP with MBB (make before break) feature mentioned in the section 8 of RFC 6388 . 7.4. mplsMldpMbbTime The mplsMldpMbbTime scalar object denotes MBB time for which LSR is waiting for MBB Ack from upstream node. This timer helps LSR to prevent waiting indefinitely for the MBB Notification from upstream node. 7.5. mplsMldpNumFecsConfigured The mplsMldpNumFecsConfigured provides a read-only counter of the number of mLDP FECs configured on this LSR. 7.6. mplsMldpNumFecsActive The mplsMldpNumFecsActive provides a read-only counter of the number of mLDP FECs Active on this LSR. 7.7. mplsMldpPlrCapable The mplsMldpPlrCapable scalar object denotes whether the LSR is capable of supporting PLR capability as specified in the section 5.1 of [MLDP_NODE_PROT] 7.8. mplsMldpMptCapable The mplsMldpMptCapable scalar object denotes whether the LSR is capable of supporting MPT capability as specified in the section 5.2 of [MLDP_NODE_PROT] 7.9. mplsMldpProtLsrCapable The mplsMldpProtLsrCapable scalar object denotes whether the LSR is capable of supporting the "Protected LSR" capability as specified in the section 5.3 of [MLDP_NODE_PROT] Kishore Tiruveedhula, et al. Expires August 4, 2014 [Page 7] Internet-Draft mLDP MIB January 2014 7.10. mplsMldpNodeProtCapable The mplsMldpNodeProtCapable scalar object denotes whether the LSR is capable of supporting the "Node Protection" capability as specified in the section 5.4 of [MLDP_NODE_PROT] 8. mLDP Table Objects 8.1. LDP Peer Capability Table mplsLdpPeerCapabilityTable The new table mplsLdpPeerCapabilityTable is read-only table, which contains learned capability information from LDP peer. This table augments the mplsLdpPeerTable, which is defined in RFC 3815. 8.2. mLDP Session Stats Table: mplsMldpSessionStatsTable The mplsMldpSessionStatsTable is a read-only table which contains mLDP statistical information on sessions. This table augments the mplsLdpSessionStatsTable, which is defined in the RFC 3815. 8.3. mLDP Fec Table: mplsMldpFecTable The mplsMldpFecTable is a table which contains FEC (Forwarding Equivalence Class) information relating to point to multi-point and multipoint to multipoint LDP LSP. Each entry/row represents a single FEC Element. This table is similar LDP LSP FEC Table, mplsLdpLspFecTable, which is defined in the RFC 3815, which associates FECs with the LSPs. 8.4. mLDP Fec Branch Traffic statistics Table: mplsMldpFecBranchStatsTable This table mplsMldpFecBranchStatsTable gives the information about number of packets and number of bytes sent out on particualr downstream session or on outgoing interface. 8.5. mLDP Fec Upstreaam Session Table: mplsMldpFecUpstreamSessTable The mplsMldpFecUpstreamSessTable is a read-only table which contains mLDP upstream session information for mLDP Fec. This table is similar to mplsInSegmentLdpLspTable. This table will also have information about primary, backup upstream session, and also indicates whether the label is in MBB request or MBB Ack received state. 8.6. mLDP Interface Traffic statistics Table: mplsMldpInterfaceStatsTable This table mplsMldpInterfaceStatsTable gives the information about Kishore Tiruveedhula, et al. Expires August 4, 2014 [Page 8] Internet-Draft mLDP MIB January 2014 number of mLDP packets and number of mLDP bytes sent and received on particualr interface for all mLDP FECs. 9. The mLDP Notifications The RFC 3815 defined some of the notifications related to session and 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. Kishore Tiruveedhula, et al.

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.
