Internet-Draft mLDP MIB January 2014
1. Introduction
This memo defines a portion of the Management Information Base (MIB)
for use with network management protocols. 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
the 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].

Internet-Draft mLDP MIB January 2014
4. Overview
This document focusses on the management of following multicast LDP
(mLDP) features, which defined after unicast LDP [RFC 5036].
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 .
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 groupd 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 Interfac3: 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 vaue
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 1, 2014 [Page 4]
Internet-Draft mLDP MIB January 2014
6.1. Summary of mLDP Scalar Objects
New scalar objects mplsMldpP2mpCapable and mplsMldpMp2mpCapable
defined to include the capabilities of mLDP like P2MP, MP2MP
capability information.
New scalar objects mplsMldpMbbCapable and mplsMldpMbbTime are defined
to include MBB 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.
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 three scalars 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 1, 2014 [Page 5]
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 configired on this LSR.
7.6. mplsMldpNumFecsActive
The mplsMldpNumFecsActive provides a read-only counter of the number
of mLDP Fecs Active on this LSR.
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
Kishore Tiruveedhula, et al. Expires August 1, 2014 [Page 6]
Internet-Draft mLDP MIB January 2014
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 packes 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
number of mLDP packes 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 satte 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.

12. Security Considerations
This MIB module is useful for the configuration of certain objects
and monitoring of mLDP LSPs.
There are a number of management objects defined in this MIB module
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:
o The mplsMldpFecTable contain objects that can be used to provision
mLDP LSPS. Unauthorized access to objects in these tables could
result in disruption of traffic in the network if the mLDP LSP has
already established.

Internet-Draft mLDP MIB January 2014
o The use of stronger mechanisms, such as SNMPv3 security, should be
considered where possible. Specifically, the SNMPv3 View-based
Access Control Model (VACM) and User-based Security Model (USM)
MUST be used with any v3 agent which implements this MIB module.
Administrators SHOULD also consider whether read access to these
objects is allowed, since read access may be undesirable under
certain circumstances as described below.
o The use of this MIB module depends on the use of certain objects
within MPLS-MLDP-STD-MIB defined in [RFC3815]. Note that those
objects are also subject to the same security considerations, and
any vulnerability to those objects could compromise the mLDP LSP
in the network. The security section of [RFC3815] MUST be applied
in conjunction with this security section.
o This MIB module may be used in conjunction with that MIB module.
If MPLS-LSR-STD-MIB is implemented on an LSR, then access to its
objects can compromise any mLDP MPLS LSPS. MPLS-LSR-STD-MIB is
defined in [RFC3813] which has its own security section that MUST
be applied in conjunction with this security section if both MIB
modules are supported.
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 mplsMldpFecBranchStatsTable
o mplsmLdpFecUpstreamSessTable
o mplsMldpSessionStatsTable
o mplsLdpPeerCapabilityTable
o mplsMldpNumFecsConfigured
o mplsMldpNumFecsActive
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.
Kishore Tiruveedhula, et al. Expires August 1, 2014 [Page 35]
Internet-Draft mLDP MIB January 2014
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.
13. IANA Considerations
This is new MPLS MIB module, contianed in this document and IANA is
requested to assign an oid under the mplsStdMIB subtree to the MPLS-
MDLP-STD-MIB module specified in this document.
