Introduction There are increasing requirements to support multi-topology in MPLS network. For example, service providers want to assign different level of service(s) to different topologies so that the service separation can be achieved. It is also possible to have an in-band management network on top of the original MPLS topology, or maintain separate routing and MPLS domains for isolated multicast or IPv6 islands within the backbone, or force a subset of an address space to follow a different MPLS topology for the purpose of security, QoS or simplified management and/or operations. Li, et al. Expires January 09, 2014 [Page 2] Internet-Draft MIB for MPLS LDP MT October 2013 For a detailed overview of the multi topology, please refer to I-D .ietf-mpls-ldp-multi-topology. 2. 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]. 3. Overview of MPLS-LDP-MT-STD-MIB objects The following subsections describe the purpose of each of the objects contained in the MPLS-LDP-MT-STD-MIB. 3.1. MPLS LDP MT Entity Table The mplsLdpEntityTable specified in [RFC3815] is used to configure information which is used by the LDP protocol to setup potential LDP Sessions. The mplsLdpMtEntityTable can be considered as an extension to mplsLdpEntityTable to setup potential LDP MT Sessions. Each entry/row in this table represents a single LDP MT Entity. There is no maximum number of LDP MT Entities specified. However, there is an mplsLdpMtEntityIndexNext object which should be retrieved by the command generator prior to creating an LDP MT Entity. If the mplsLdpMtEntityIndexNext object is zero, this indicates that the LSR/ LER is not able to create another LDP MT Entity at that time. 3.2. MPLS LDP MT Entity Statistics Table This table provides MPLS Multi Topology performance information on a per-interface basis. 3.3. MPLS LDP MT Session Table Since all the MT related label messages can be advertised by LDP Sessions in default topology, there is no need to create extra tcp connection for Multi Topology. Li, et al. Expires January 09, 2014 [Page 3] Internet-Draft MIB for MPLS LDP MT October 2013 The mplsLdpMtSessionTable is a read-only table. Each entry in this table represents an MT Session which is related to one or more LDP MT Entities and only one LDP Session in default topology. 3.4. MPLS LDP MT In-segment Tables The mplsLdpMtInSegmentTable contains information about the MPLS Label Distribution Protocol Multi Topology In-Segments which exist on this Label Switching Router (LSR) or Label Edge Router (LER). The mplsLdpMtInSegmentStatsTable contains statistical information for LDP MT in-segments. 3.5. MPLS LDP MT Out-segment Tables This table contains information about the MPLS Label Distribution Protocol Multi Topology Out-Segments which exist on this Label Switching Router (LSR) or Label Edge Router (LER). The mplsLdpMtInSegmentStatsTable contains statistical information for LDP MT out-segments. 3.6. MPLS LDP MT LSP Table This table specifies MT LIB label switching information. Entries in this table define LIB label switching entries associated with the specified FEC of the specified topology. 3.7. MPLS LDP MT Notifications The mplsLdpMtLspUp and mplsLdpMtLspDown notifications are generated when there is an appropriate change in the mplsLdpMtLspOperStatus object, e.g., when the LSP changes state (Up to Down for the mplsLdpMtLspDown notification, or Down to Up for the mplsLdpMtLspUp notification). 4.
