1. 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.

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).

mplsLdpMtLspOperStatus MUST both be set equal to this new

range of cross-connects have transitioned into the up(1) state
at roughly the same time, the device SHOULD issue a single

to minimize the emission of a large number of notifications.
If a notification has to be issued for just a single

has been initiated with a Peer, changing objects in this table
will wreak havoc with the session and interrupt traffic. To
repeat again: the recommended procedure is to set the
mplsLdpMtEntityAdminStatus to down, thereby explicitly causing
a session to be torn down. Then, change objects in this entry,
