1. Introduction
This memo defines a portion of the Management Information Base (MIB)
containing objects used to manage Multiprotocol Label
Switching (MPLS)-based fast rerouting features on MPLS Label
Switching Routers as defined in [RFC4090]. This MIB module should
be used in conjunction with [RFC3811], [RFC3812] and [RFC3813].
Comments should be made directly to the MPLS mailing list at
mpls@ietf.org.
1.1. 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 [RFC2119].
2. Terminology
Nadeau, et al. Expires Dec 2008 [Page 2]
MPLS Fast-reroute MIB June 27, 2008
This document uses terminology from the document describing the
Multiprotocol Label Switching Architecture [RFC3031] and from
the document describing Fast Reroute Extensions to RSVP-TE for
LSP Tunnels [RFC4090].
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
[RFC3410].
Managed objects are accessed via a virtual information store, termed
the Management Information Base or MIB. MIB module 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. Overview of the MIB Module
The specification [RFC4090] stipulates two different approaches
to implementing MPLS TE fast reroute: one-to-one and facility
backup.
We define three MIB modules to represent the respective
components: general, one-to-one and facility backup.
They are:
- MPLS-FRR-GENERAL-STD-MIB: Contains objects that apply to any
MPLS LSR implementing MPLS TE fast reroute functionality.
- MPLS-FRR-ONE2ONE-STD-MIB: Contains objects that apply to
one-to-one backup method.
- MPLS-FRR-FACILITY-STD-MIB: Contains objects that apply to
facility backup method.
Although [RFC4090] specifies that a node is able to support both
fast reroute methods simultaneously, common practice has shown
that operators choose to configure either one-to-one backup method
or facility backup at any given time. So by dividing the MIB
modules into three, we allow the developers to choose the MIB
modules they want to implement depending on the method supported
on that node.
4.1. MPLS-FRR-GENERAL-STD-MIB
Nadeau, et al. Expires Dec 2008 [Page 3]
MPLS Fast-reroute MIB June 27, 2008
4.1.1 mplsFrrConstraintsTable
This table contains objects that apply to all LSRs
implementing MPLS TE fast reroute functions. In particular,
this table defines fast reroute constraints such as
bandwidth for a tunnel instance to be protected by using
backup LSPs (detour LSPs or bypass tunnels).
This table is used at the ingress node of the protected TE
tunnel instance to configure backup LSP setup constraints.
4.1.2 mplsFrrTunnelARHopTable
This table extends mplsTunnelARHopTable (defined in the
MPLS-TE-STD-MIB [RFC3812]) with fast-reroute objects which
specify the local protection type or types of availability
as well as what type or types are actally in-use for each
tunnel hop traversed by a protected TE tunnel.
The support of this table is only required when the
Record Route Object (RRO) is supported by the implementation.
4.2. MPLS-FRR-ONE2ONE-STD-MIB
4.2.1 mplsFrrOne2OnePlrTable
The mplsFrrOne2OnePlrTable contains information about PLRs that
initiated detour LSPs to protect tunnel instances. This table
is mandatory for LSRs implementing the one-to-one backup method.
In these cases, the detour LSPs are reflected in the
mplsFrrOne2OneDetourTable.
4.2.2 mplsFrrOne2OneDetourTable
The mplsFrrOne2OneDetourTable shows the detour LSPs in each node
(ingress, transit and egress nodes). An entry of this table
represents a detour LSP.
Each detour is identified by the following indexes:
- mplsTunnelIndex [RFC3812]:
set to the tunnel-id of an LSP protected by a detour.
- mplsTunnelInstance [RFC3812]: consists of two parts
1) the lower 16 bits: - protected TE tunnel instance
- uniquely identifies a protected
LSP within a tunnel.
Nadeau, et al. Expires Dec 2008 [Page 4]
MPLS Fast-reroute MIB June 27, 2008
2) the higher 16 bits: - detour instance
- uniquely identifies a detour LSP
of a protected TE tunnel instance.
Multiple detours of the same
protected LSP may go through the
same node. In this case, the
higher 16 bits of the tunnel
instance object is used as a
detour instance.
- ingress node's LSR ID (mplsFrrOne2OnePlrTunIngrLSRId):
set to the ingress node of an LSP protected by a detour.
- egress node's LSR ID (mplsFrrOne2OnePlrTunEgrLSRId):
set to the egress node of an LSP protected by a detour.
A detour LSP is also considered as an instance of a protected
TE tunnel. Therefore, each detour LSP SHOULD have an entry in
the mplsTunnelTable (defined in the MPLS-TE-STD-MIB[RFC3812]).
In the mplsTunnelTable, the higher 16 bits of the tunnel instance
SHOULD be used as a detour instance. Note that for the protected
TE tunnel instances, the higher 16 bits of the tunnel instance
MUST all be set to zero.
This table is mandatory if one-to-one backup method is used.
4.3 MPLS-FRR-FACILITY-STD-MIB
4.3.1 mplsFrrFacilityDBTable
The mplsFrrFacilityDBTable provides information about the fast
reroute database for facility-based fast reroute.
An entry is created in this table for each tunnel being
protected by a backup tunnel. Backup tunnels defined
to protect the tunnels traversing an interface.
The protecting tunnel is defined to exist on the PLR in
the MPLS TE fast reroute specification. Protected tunnels are
the LSPs that traverse the protected link.
Implementation of this table is mandatory when facility backup is
used.
5. Handling IPv6 Tunnels
As described in [RFC4990], in order to support IPv6 MPLS
tunnels in the mplsTunnelTable [RFC3812] all LSRs in the network
MUST have a 32-bit LSR ID that can be used to identify the LSR
with the existing mplsTunnelIngressLSRId and mplsTunnelEgressLSRId
Nadeau, et al. Expires Dec 2008 [Page 5]
MPLS Fast-reroute MIB June 27, 2008
objects which are 32-bit long.
In this MIB, the following objects which refer to ingress/egress
LSRs will have then the 32-bit LSR ID to support IPv6 tunnels:
- mplsFrrOne2OnePlrTunIngrLSRId and
- mplsFrrOne2OnePlrTunEgrLSRId
objects of the mplsFrrOne2OnePlrTable,
- mplsFrrOne2OnePlrTunIngrLSRId and
- mplsFrrOne2OnePlrTunEgrLSRId
objects of the mplsFrrOne2OneDetourTable
- mplsFrrFacilityBackupTunnelIngressLSRId and
- mplsFrrFacilityBackupTunnelEgressLSRId
objects of the mplsFrrFacilityDBTable

as indicated by the presense of the FAST_REROUTE Object
in the signaling for the LSP in question.
Entries indexed with mplsFrrConstraintsIfIndexOrZero set to 0
apply to all interfaces on this device for which the FRR
feature can operate.
Note that as per [RFC3812] the mplsTunnelInstance object
set to a value of 0 indicates that the mplsTunnelEntry
contains a tunnel ingress. This is typically how
configuration of this feature is performed on devices
where the actual protection LSP used is left up to the
protecting tunnel. However, in cases where static
configuration is possible, any valid tunnel
instance is possible; however, in these cases, it is
STRONGLY RECOMMENDED that the instance index SHOULD
use the following convention to identify backup LSPs:
- lower 16 bits : protected tunnel instance
- higher 16 bits: must be all zeros

DESCRIPTION
"This notification is generated when a tunnel running over an
interface as specified in the mplsFrrConstraintsTable is
initially protected by the backup tunnel also specified in the
mplsFrrConstraintsTable. In some implementations there may be
a difference between when the control plane triggers
this notification and when the hardware is programmed to
utilize the protection path. Due to the urgency of this
operation, it is acceptable for the control plane to
either issue this notification before or after it programs
the hardware. In cases where it is the latter approach,
the notification MUST be sent immediately after the
data plane has been altered.
This notification should not be generated
for each subsequent tunnel that is backed up by the FRR feature
on this LSR, as this may result in potential scaling issues
with regard to LSR performance and network load. Note also
that notifications MUST be generated in accordance with the
mplsFrrNotificationsMaxRate.
Note this notification is only applicable to the facility based
fastreroute protection method, and should be ignored by
implementations that do not support this method."

7. Security Considerations
It is clear that these MIB modules are potentially useful for
monitoring of MPLS LSRs supporting fast reroute. This
MIB module can also be used for configuration of certain objects,
Nadeau, et al. Expires Dec 2008 [Page 39]
MPLS Fast-reroute MIB June 27, 2008
and anything that can be configured can be incorrectly configured,
with potentially disastrous results.
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 mplsFrrConstraintsTable and some objects in the
mplsFrrScalarGroup contain objects which may be used
to provision MPLS fast reroute features. Unauthorized
access to these objects could result in disruption of
traffic on the network. This is especially true if the
objects in question refer to previously provisioned protection
tunnels and configuration. The use of stronger
mechanisms such as SNMPv3 security should be considered where
possible. Specifically, SNMPv3 VACM and USM MUST be used with
any v3 agent which implements this MIB module. Administrators
should consider whether read access to these objects should
be allowed, since read access may be undesirable under certain
circumstances.
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 the mplsFrrOne2OnePlrTable, mplsFrrOne2OneDetourTable, and
mplsFrrTunnelARHopTable tables and some objects
contained in the mplsFrrScalarGroup
collectively show the MPLS fast reroute interfaces, tunnels,
and other associated fast reroute feature configurations
as well as their linkages to other MPLS-related
configuration and/or performance statistics.
Administrators not wishing to reveal this information should
consider these objects sensitive/vulnerable and take
precautions so they are not revealed.
SNMP versions prior to SNMPv3 did not include adequate security.
Even if the network itself is secure (for example by using IPSec),
even then, there is no control as to who on the secure network is
allowed to access and GET/SET (read/change/create/delete) the objects
Nadeau, et al. Expires Dec 2008 [Page 40]
MPLS Fast-reroute MIB June 27, 2008
in this MIB module.
It is RECOMMENDED that implementers consider the security features as
provided by the SNMPv3 framework (see [RFC3410], section 8),
including full support for the SNMPv3 cryptographic mechanisms (for
authentication and privacy).
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.
8. IANA Considerations
As described in the MPLS-TC-STD-MIB [RFC3811] MIB module, MPLS
related standards track MIB modules should be rooted under the
mplsStdMIB subtree. There is one MPLS-related
MIB module contained in this document. The following "IANA
Considerations" subsection requests IANA for a new assignment under
the mplsStdMIB subtree. New assignments can only be made via a
Standards Action as specified in [RFC5226].
8.1. IANA Considerations for MPLS-FRR-STD-MIB
The IANA is requested to assign { mplsStdMIB 12 } to the
MPLS-FRR-STD-MIB MIB module specified in this document.
