the Optimized Link State Routing Protocol Version 2
Abstract
This document defines the Management Information Base (MIB) module
for configuring and managing the Optimized Link State Routing
Protocol version 2 (OLSRv2). The OLSRv2-MIB module is structured
into configuration information, state information, performance
information, and notifications. This additional state and
performance information is useful for troubleshooting problems and
performance issues of the routing protocol. Two levels of compliance
allow this MIB module to be deployed on constrained routers.

1. Introduction
This document defines the Management Information Base (MIB) module
for configuring and managing the Optimized Link State Routing
Protocol version 2 (OLSRv2). The OLSRv2-MIB module is structured
into configuration information, state information, performance
information, and notifications. In addition to configuration, this
additional state and performance information is useful for
troubleshooting problems and performance issues of the routing
protocol. Different levels of compliance allow implementers to use
smaller subsets of all defined objects, allowing for this MIB module
to be deployed on more constrained routers.

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
[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 module are defined using the mechanisms defined in
the Structure of Management Information (SMI). This document
specifies a MIB module that is compliant to the SMIv2, which is
described in STD 58, [RFC2578], STD 58, [RFC2579] and STD 58
[RFC2580].
3. Conventions
The key words "MUST", "MUST NOT", "REQUIRED", "SHALL", "SHALL NOT",
"SHOULD", "SHOULD NOT", "RECOMMENDED", "NOT RECOMMENDED", "MAY", and
"OPTIONAL" in this document are to be interpreted as described in
[RFC2119].
4. Overview
The Optimized Link State Routing Protocol version 2 (OLSRv2)
[RFC7181] is a table-driven, proactive routing protocol, i.e., it
exchanges topology information with other routers in the network
periodically. OLSRv2 is an optimization of the classical link state
routing protocol. Its key concept is that of multipoint relays
(MPRs). Each router selects a set of its neighbor routers (which
"cover" all of its symmetrically connected 2-hop neighbor routers) as
MPRs. MPRs are then used to achieve both flooding reduction and
topology reduction.
This document provides management and control capabilities of an
OLSRv2 instance, allowing management applications to monitor the
state and performance of an OLSRv2 router, as well as to change
settings of the OLSRv2 instance (e.g., router or interface parameters
such as message intervals, etc.).
As OLSRv2 relies on the neighborhood information discovered by the
"Mobile Ad Hoc Network (MANET) Neighborhood Discovery Protocol
(NHDP)" [RFC6130], the OLSRv2-MIB module is aligned with the NHDP-MIB
module [RFC6779] and augments several of the tables and objects in
the NHDP-MIB. In particular, common indexes for router interfaces
and discovered neighbors are used, as described in Section 5.2.
Herberg, et al. Standards Track [Page 3]

RFC 7184 The OLSRv2-MIB April 2014
4.1. Terms
The following definitions apply throughout this document:
o Configuration Objects - switches, tables, and objects that are
initialized to default settings or set through the management
interface defined by this MIB module.
o State Objects - automatically generated values that define the
current operating state of the OLSRv2 protocol instance in the
router.
o Performance Objects - automatically generated values that help an
administrator or automated tool to assess the performance of the
OLSRv2 process on the router.
o Notification Objects - objects that define triggers and associated
notification messages allowing for asynchronous tracking of
predefined events on the managed router.
5. Structure of the MIB Module
This section presents the structure of the OLSRv2-MIB module. The
objects are arranged into the following structure:
o olsrv2MIBObjects - defines objects forming the basis for the
OLSRv2-MIB module. These objects are divided up by function into
the following groups:
* Configuration Group - defining objects related to the
configuration of the OLSRv2 instance on the router.
* State Group - defining objects that reflect the current state
of the OLSRv2 instance running on the router.
* Performance Group - defining objects that are useful to a
management system when characterizing the performance of OLSRv2
on the router and in the MANET.
o olsrv2MIBNotifications - objects defining OLSRv2-MIB module
notifications.
o olsrv2MIBConformance - defining the minimal and maximal
conformance requirements for implementations of this MIB module.
Herberg, et al. Standards Track [Page 4]
^L
RFC 7184 The OLSRv2-MIB April 2014
5.1. The Configuration Group
The OLSRv2 router is configured with a set of controls. The
authoritative list of configuration controls within the OLSRv2-MIB
module is found within the MIB module itself. Generally, an attempt
was made in developing the OLSRv2-MIB module to support all
configuration objects defined in [RFC7181]. For all of the
configuration parameters, the same constraints and default values of
these parameters as defined in [RFC7181] are followed.
5.2. The State Group
The State Group reports current state information of a router running
[RFC7181]. The OLSRv2-MIB module State Group tables were designed to
contain the complete set of state information defined within the
Information Bases in [RFC7181].
The OLSRv2-MIB module State Group tables are constructed as
extensions to the corresponding tables within the State Group of the
NHDP-MIB module [RFC6779]. Use of the AUGMENTS clause is made, when
possible, to accomplish these table extensions. Further, the State
Group tables defined in this MIB module are aligned with the
corresponding tables in the NHDP-MIB module [RFC6779], as described
in Section 6.2.
5.3. The Performance Group
The Performance Group reports values relevant to system performance.
Frequent changes of sets or frequent recalculation of the Routing Set
or the MPRs can have a negative influence on the performance of
OLSRv2. This MIB module defines several objects that can be polled,
e.g., in order to calculate histories or monitor frequencies of
changes. This may help the network administrator to determine
unusual topology changes or other changes that affect stability and
reliability of the MANET. One such framework is specified in REPORT-
MIB [REPORT-MIB].
5.4. The Notifications Group
The Notifications Group contains Control
(olsrv2NotificationsControl), Objects (olsrv2NotificationsObjects),
and States (olsrv2NotificationsStates), where the Control contains
definitions of objects to control the frequency of notifications
being generated. The Objects define the supported notifications, and
the State is used to define additional information to be carried
within the notifications.
Herberg, et al. Standards Track [Page 5]
^L
RFC 7184 The OLSRv2-MIB April 2014
The olsrv2NotificationsObjects sub-tree contains the list of
notifications supported within the OLSRv2-MIB module and their
intended purpose or utility.
The same mechanisms for improving the network performance by reducing
the number of notifications apply as defined in Section 5.1 of
[RFC6779]. The following objects are used to define the thresholds
and time windows for specific notifications defined in the NHDP-MIB
module: olsrv2RoutingSetRecalculationCountThreshold,
olsrv2RoutingSetRecalculationCountWindow,
olsrv2MPRSetRecalculationCountThreshold, and
olsrv2MPRSetRecalculationCountWindow.
5.5. Tables and Indexing
The OLSRv2-MIB module's tables are indexed by the following
constructs:
o nhdpIfIndex - the ifIndex of the local router on which NHDP is
configured. This is defined in the NHDP-MIB.
o nhdpDiscIfIndex - a locally managed index representing a known
interface on a neighboring router. This is defined in the NHDP-
MIB.
o nhdpDiscRouterIndex - a locally managed index representing an ID
of a known neighboring router. This is defined in the NHDP-MIB.
o {olsrv2LibOrigSetIpAddrType, olsrv2LibOrigSetIpAddr} - this index
(pair) uniquely identifies recently used originator addresses
found within the olsrv2LibOrigSetTable.
o {olsrv2LibLocAttNetSetIpAddrType, olsrv2LibLocAttNetSetIpAddr,
olsrv2LibLocAttNetSetIpAddrPrefixLen} - this index (triplet)
uniquely identifies local attached networks reachable through
local (non-OLSRv2) interfaces on this router. These are recorded
in the olsrv2LibLocAttNetSetTable.
o {olsrv2TibAdRemoteRouterSetIpAddrType,
olsrv2TibAdRemoteRouterSetIpAddr} - this index (pair) uniquely
identifies each router in the network that transmits Topology
Control (TC) messages received by this router. These records are
recorded in the olsrv2TibAdRemoteRouterSetIpAddr.
o {olsrv2TibRouterTopologySetFromOrigIpAddrType,
olsrv2TibRouterTopologySetFromOrigIpAddr,
olsrv2TibRouterTopologySetToOrigIpAddrType,
olsrv2TibRouterTopologySetToOrigIpAddr} - this index (quadruplet)
Herberg, et al. Standards Track [Page 6]
^L
RFC 7184 The OLSRv2-MIB April 2014
uniquely identifies discovered links within the network recorded
by this router. Information associated with each link is stored
in the olsrv2TibRouterTopologySetTable.
o {olsrv2TibRoutableAddressTopologySetFromOrigIpAddrType,
olsrv2TibRoutableAddressTopologySetFromOrigIpAddr,
olsrv2TibRoutableAddressTopologySetFromDestIpAddrType,
olsrv2TibRoutableAddressTopologySetFromDestIpAddr} - this index
(quadruplet) uniquely identifies reachable addresses within the
network and the router's advertising of these addresses. This
information is stored in the
olsrv2TibRoutableAddressTopologySetTable.
o {olsrv2TibAttNetworksSetOrigIpAddrType,
olsrv2TibAttNetworksSetOrigIpAddr,
olsrv2TibAttNetworksSetNetIpAddrType,
olsrv2TibAttNetworksSetNetIpAddr,
olsrv2TibAttNetworksSetNetIpAddrPrefixLen} - this index
(quintuplet) uniquely identifies the networks (which may be
outside the MANET) and the routers through which these networks
can be reached. This information is stored in the
olsrv2TibAttNetworksSetTable.
o {olsrv2TibRoutingSetDestIpAddrType, olsrv2TibRoutingSetDestIpAddr,
olsrv2TibRoutingSetDestIpAddrPrefixLen} - this index (triplet)
uniquely identifies the address of a reachable destination in the
network. This indexes the olsrv2TibRoutingSetTable, which
contains the next-hop information to reach the indexed addresses.
These tables and their indexing are:
o olsrv2InterfaceTable - describes the OLSRv2 status on the NHDP
interfaces of this router. This table augments nhdpInterfaceEntry
and, as such, it is indexed by the {nhdpIfIndex} from the NHDP-
MIB.
o olsrv2IibLinkSetTable - records all links from other routers that
are, or recently were, 1-hop neighbors. This table augments
nhdpIibLinkSetEntry and, as such, it is indexed by nhdpIfIndex and
nhdpDiscIfIndex.
o olsrv2Iib2HopSetTable - records network addresses of symmetric
2-hop neighbors and the links to the associated 1-hop neighbors.
This table augments nhdpIib2HopSetEntry and, as such, it is
indexed by {nhdpIfIndex, nhdpDiscIfIndex,
nhdpIib2HopSetIpAddressType, nhdpIib2HopSetIpAddress}.
Herberg, et al. Standards Track [Page 7]
^L
RFC 7184 The OLSRv2-MIB April 2014
o olsrv2LibOrigSetTable - records addresses that were recently used
as originator addresses by this router. This table is indexed by
{olsrv2LibOrigSetIpAddrType, olsrv2LibOrigSetIpAddr}.
o olsrv2LibLocAttNetSetTable - records its local non-OLSRv2
interfaces via which it can act as a gateway to other networks.
This table is indexed by {olsrv2LibLocAttNetSetIpAddrType,
olsrv2LibLocAttNetSetIpAddr,
olsrv2LibLocAttNetSetIpAddrPrefixLen}.
o olsrv2NibNeighborSetTable - records all network addresses of each
1-hop neighbor. This table augments nhdpNibNeighborSetEntry and,
as such, it is indexed by the {nhdpDiscRouterIndex}.
o olsrv2TibAdRemoteRouterSetTable - records information describing
each remote router in the network that transmits TC messages.
This table is indexed by {olsrv2TibAdRemoteRouterSetIpAddrType,
olsrv2TibAdRemoteRouterSetIpAddr}.
o olsrv2TibRouterTopologySetTable - records topology information
about the network. This table is indexed by
{olsrv2TibRouterTopologySetFromOrigIpAddrType,
olsrv2TibRouterTopologySetFromOrigIpAddr,
olsrv2TibRouterTopologySetToOrigIpAddrType,
olsrv2TibRouterTopologySetToOrigIpAddr}.
o olsrv2TibRoutableAddressTopologySetTable - records topology
information about the routable addresses within the MANET and via
which routers they may be reached. This table is indexed by
{olsrv2TibRoutableAddressTopologySetFromOrigIpAddrType,
olsrv2TibRoutableAddressTopologySetFromOrigIpAddr,
olsrv2TibRoutableAddressTopologySetFromDestIpAddrType,
olsrv2TibRoutableAddressTopologySetFromDestIpAddr}.
o olsrv2TibAttNetworksSetTable - records information about networks
(which may be outside the MANET) attached to other routers and
their routable addresses. This table is indexed by
{olsrv2TibAttNetworksSetOrigIpAddrType,
olsrv2TibAttNetworksSetOrigIpAddr,
olsrv2TibAttNetworksSetNetIpAddrType,
olsrv2TibAttNetworksSetNetIpAddr,
olsrv2TibAttNetworksSetNetIpAddrPrefixLen}.
o olsrv2TibRoutingSetTable - records the first hop along a selected
path to each destination for which any such path is known. This
table is indexed by {olsrv2TibRoutingSetDestIpAddrType,
olsrv2TibRoutingSetDestIpAddr,
olsrv2TibRoutingSetDestIpAddrPrefixLen}.
Herberg, et al. Standards Track [Page 8]
^L
RFC 7184 The OLSRv2-MIB April 2014
o olsrv2InterfacePerfTable - records performance counters for each
active OLSRv2 interface on this device. This table augments
nhdpInterfacePerfEntry and, as such, it is indexed by
{nhdpIfIndex} from the NHDP-MIB.
6. Relationship to Other MIB Modules
This section specifies the relationship of the MIB modules contained
in this document to other standards, particularly to standards
containing other MIB modules. MIB modules and specific definitions
imported from MIB modules that SHOULD be implemented in conjunction
with the MIB module contained within this document are identified in
this section.
6.1. Relationship to the SNMPv2-MIB
The System group in the SNMPv2-MIB module [RFC3418] is defined as
being mandatory for all systems, and the objects apply to the entity
as a whole. The System group provides identification of the
management entity and certain other system-wide data. The OLSRv2-MIB
module does not duplicate those objects.
6.2. Relationship to the NHDP-MIB
OLSRv2 depends on the neighborhood information that is discovered by
[RFC6130]. An instance of OLSRv2 MUST have an associated instance of
NHDP running on the same device for proper operations of the
discovery and routing system. In order for the OLSRv2-MIB module to
correctly populate the objects relating to discovered neighbors, the
State Group tables of the NHDP-MIB module [RFC6779] are aligned with
the State Group tables of this MIB module. This is accomplished
through the use of the AUGMENTS capability of SMIv2 (where
appropriate). This will allow for cross referencing of information
between the two MIB modules within a given SNMP context.
6.3. MIB Modules Required for IMPORTS
The following OLSRv2-MIB module IMPORTS objects from NHDP-MIB
[RFC6779], SNMPv2-SMI [RFC2578], SNMPv2-TC [RFC2579], SNMPv2-CONF
[RFC2580], IF-MIB [RFC2863], and INET-ADDRESS-MIB [RFC4001]. The
OLSRv2-MIB module also IMPORTS objects from the
IANAolsrv2LinkMetricType-MIB, which is available at <http://
www.iana.org/assignments/ianaolsrv2linkmetrictype-mib>.

Olsrv2MetricValueCompressedFormTC ::= TEXTUAL-CONVENTION
DISPLAY-HINT "d"
STATUS current
DESCRIPTION
"OLSRv2 Metrics are expressed in terms of a Link Metric
Compressed Form within the OLSRv2 protocol. This textual
convention defines the syntax of the metric objects
consistent with the definitions of the OLSRv2 Link
Metric Compressed Form in Section 6.2 of RFC 7181.
The 12-bit compressed form of a link metric uses a modified
form of a representation with an 8-bit mantissa (denoted a)
and a 4-bit exponent (denoted b). Note that if represented
as the 12-bit value 256b+a, then the ordering of those 12-bit
values is identical to the ordering of the represented values.
The value so represented is (257+a)2^b - 256, where ^ denotes
exponentiation. This has a minimum value
(when a = 0 and b = 0) of MINIMUM_METRIC = 1 and a maximum
value (when a = 255 and b = 15) of MAXIMUM_METRIC = 2^24 - 256.
Hence, the metric values so represented range from 1 to
16776960. The special value of 0 is reserved for the
UNKNOWN_METRIC value.
If a network manager sets the metric value 'm' through the
MIB module, then the OLSRv2 code can both use this value
and derive a compressed representation of 'm' (as used in
messages) as specified in Section 6.2 of RFC7181.
The value 'm' is persistently stored by the MIB module.
If the MIB module is pulling this metric's value from some other
source, e.g., the protocol instance, then this value is stored
as is."

Olsrv2TimeValueCompressedForm32TC ::= TEXTUAL-CONVENTION
DISPLAY-HINT "x"
STATUS current
DESCRIPTION
"OLSRv2 time values may be expressed in terms of a compressed
form within the OLSRv2 protocol. This textual convention
defines the syntax of the time objects defined in terms of
an integer number of milliseconds, consistent with the
definitions of the 8-bit exponent-mantissa compressed form
Herberg, et al. Standards Track [Page 12]
^L
RFC 7184 The OLSRv2-MIB April 2014
defined in Section 5 of RFC 5497. Time values with this
representation are defined in terms of a constant C, which
is represented in terms of seconds. The constant C
(time granularity) is used as specified in RFC 5497.
It MUST be the same as is used by NHDP (RFC 6130).
The 8-bit compressed form of a time value uses a modified
form of a representation with a 3-bit mantissa (denoted a)
and a 5-bit exponent (denoted b). Note that if represented
as the 8-bit value 8b+a, then the ordering of those 8-bit
values is identical to the ordering of the represented values.
The minimum time value that can be represented in this manner
is C. The maximum time value that can be represented in
this manner is 15 * 2^28 * C, 15*268,435,456 * C,
4,026,531,840 * C, or about 45 days if, for example,
C = 1/1024 second.
This TEXTUAL-CONVENTION limits the maximum value of the
time granularity constant C to be no greater than 1/1024
seconds due to its use of the Unsigned32 syntax limiting
the maximum number of milliseconds to no more than
3932160000.
When OLSRv2 uses this 8-bit exponent-mantissa compressed
form, this object value MUST be translated from the
integer form represented in this MIB module into the
exponent-mantissa form for the OLSRv2 protocol to use
according to the algorithm defined in Section 5 of
RFC 5497 for finding the next larger time value within
the exponent-mantissa format.
If a network manager sets the time value 't' through the
MIB module, then the OLSRv2 code can derive
'compressed_t' = T(a,b) according to the algorithm
in RFC 5497 and 'compressed_t' is the value represented
in the OLSRv2 messages. But, the value 't' is persistently
stored by the MIB module. If the MIB module is pulling
this time parameter from some other source that is using
the compressed form, i.e., the protocol instance, then
this value is stored as is, after converting from
number of time constants C into number of milliseconds."

status on the NHDP interfaces of this router.
As such, this table augments the nhdpInterfaceTable
defined in the NHDP-MIB (RFC 6779). NHDP interfaces
are explicitly defined by network management, command
line interface (CLI) or other means for interfaces on
the device that are intended to run MANET protocols.
The olsrv2InterfaceTable contains a single object: the
olsrv2InterfaceAdminStatus object. This
object is set by network management, or by
Herberg, et al. Standards Track [Page 15]
^L
RFC 7184 The OLSRv2-MIB April 2014
other means, e.g., CLI.
A conceptual row in this table exists if and only
if a corresponding entry in the nhdpInterfaceTable
exists. If the corresponding entry with nhdpIfIndex
value is deleted from the nhdpInterfaceTable, then
the entry in this table is automatically deleted and
OLSRv2 is disabled on this interface,
and all configuration and state information
related to this interface is to be removed
from memory.
The olsrv2InterfaceAdminStatus can only be
'enabled' if the corresponding olsrv2AdminStatus
object is also set to 'enabled'."

DESCRIPTION
"This is the greatest Advertised Neighbor Sequence
Number (ANSN) in any TC message
received that originated from the router
with originator address
olsrv2TibAdRemoteRouterSetIpAddr.
Sequence numbers are used in the OLSRv2 protocol
for the purpose of discarding 'old' information,
i.e., messages received out of order. However,
with a limited number of bits for representing
sequence numbers, wraparound (that the sequence
number is incremented from the maximum possible
value to zero) will occur. To prevent this from
interfering with the operation of this protocol,
OLSRv2 implementations observe the following when
determining the ordering of sequence numbers.
In OLSRv2, MAXVALUE designates one more than the
largest possible value for a sequence number.
For a 16-bit sequence number, MAXVALUE is 65536.
The sequence number S1 is said to be 'greater than'
the sequence number S2 if:
o S1 > S2 AND S1 - S2 < MAXVALUE/2 OR
o S2 > S1 AND S2 - S1 > MAXVALUE/2
When sequence numbers S1 and S2 differ by MAXVALUE/2,
their ordering cannot be determined. In this case,

which should not occur, either ordering may be
assumed.
Thus, when comparing two messages, it is possible
- even in the presence of wraparound - to determine
which message contains the most recent information."

i.e., that contributed to the information
contained in this Tuple and that is defined by the
objects:
(olsrv2TibRouterTopologySetFromOrigIpAddrType,

Sequence numbers are used in the OLSRv2 protocol
for the purpose of discarding 'old' information,
i.e., messages received out of order. However,
with a limited number of bits for representing
sequence numbers, wraparound (that the sequence
number is incremented from the maximum possible
value to zero) will occur. To prevent this from
interfering with the operation of this protocol,
OLSRv2 implementations observe the following when
determining the ordering of sequence numbers.
In OLSRv2, MAXVALUE designates one more than the
largest possible value for a sequence number.
For a 16-bit sequence number, MAXVALUE is 65536.
The sequence number S1 is said to be 'greater than'
the sequence number S2 if:
o S1 > S2 AND S1 - S2 < MAXVALUE/2 OR
o S2 > S1 AND S2 - S1 > MAXVALUE/2
When sequence numbers S1 and S2 differ by MAXVALUE/2,

their ordering cannot be determined. In this case,
which should not occur, either ordering may be
assumed.
Thus, when comparing two messages, it is possible
- even in the presence of wraparound - to determine
which message contains the most recent information."

8. Security Considerations
This MIB module defines objects for the configuration, monitoring,
and notification of the Optimized Link State Routing Protocol version
2 (OLSRv2) [RFC7181]. OLSRv2 allows routers to acquire topological
information of the routing domain by exchanging TC messages in order
to calculate shortest paths to each destination router in the routing
domain.
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
Herberg, et al. Standards Track [Page 77]
^L
RFC 7184 The OLSRv2-MIB April 2014
environment without proper protection can have a negative effect on
network operations. These are the tables and objects and their
sensitivity/vulnerability:
o olsrv2TcInterval, olsrv2TcMinInterval - these writable objects
control the rate at which TC messages are sent. If set at too
high a rate, this could represent a form of a DoS attack by
overloading interface resources. If set too low, OLSRv2 may not
converge fast enough to provide accurate routes to all
destinations in the routing domain.
o olsrv2TcHopLimit - defines the hop limit for TC messages. If set
too low, messages will not be forwarded beyond the defined scope;
thus, routers further away from the message originator will not be
able to construct appropriate topology graphs.
o olsrv2OHoldTime, olsrv2THoldTime, olsrv2AHoldTime,
olsrv2RxHoldTime, olsrv2PHoldTime, olsrv2FHoldTime - define hold
times for tuples of different Information Bases of OLSRv2. If set
too low, information will expire quickly, and may this harm a
correct operation of the routing protocol.
o olsrv2WillFlooding and olsrv2WillRouting - define the willingness
of this router to become MPR. If this is set to WILL_NEVER (0),
the managed router will not forward any TC messages, nor accept a
selection to become MPR by neighboring routers. If set to
WILL_ALWAYS (15), the router will be preferred by neighbors during
MPR selection and may thus attract more traffic.
o olsrv2TpMaxJitter, olsrv2TtMaxJitter, olsrv2FMaxJitter - define
jitter values for TC message transmission and forwarding. If set
too low, control traffic may get lost when collisions occur.
o olsrv2LinkMetricType - defines the type of the link metric that a
router uses (e.g., ETX or hop count). Whenever this value
changes, all link metric information recorded by the router is
invalid, causing a reset of information acquired from other
routers in the MANET. Moreover, if olsrv2LinkMetricType on a
router is set to a value that is not known to other routers in the
MANET, these routers will not be able to establish routes to that
router or transiting that router. Existing routes to the router
with an olsrv2LinkMetricType unknown to other routers in the MANET
will be removed.
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
Herberg, et al. Standards Track [Page 78]
^L
RFC 7184 The OLSRv2-MIB April 2014
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 olsrv2TibRouterTopologySetTable - The contains information on the
topology of the MANET, specifically the IP address of the routers
in the MANET (as identified by
olsrv2TibRouterTopologySetFromOrigIpAddr and
olsrv2TibRouterTopologySetToOrigIpAddr objects). This information
provides an adversary broad information on the members of the
MANET, located within this single table. This information can be
used to expedite attacks on the other members of the MANET without
having to go through a laborious discovery process on their own.
Some of the Tables in this MIB module AUGMENT Tables defined in NHDP-
MIB [RFC6779]. Hence, care must be taken in configuring access
control here in order make sure that the permitted permissions
granted for the AUGMENTing Tables here are consistent with the access
controls permitted within the NHDP-MIB. The below list identifies
the AUGMENTing Tables and their NHDP-MIB counterparts. It is
RECOMMENDED that access control policies for these Table pairs are
consistently set.
o The olsrv2InterfaceTable AUGMENTs the nhdpInterfaceTable.
o The olsrv2IibLinkSetTable AUGMENTs the nhdpIibLinkSetTable.
o The olsrv2Iib2HopSetTable AUGMENTs the nhdpIib2HopSetTable.
o The olsrv2NibNeighborSetTable AUGMENTs the
nhdpNibNeighborSetTable.
o The olsrv2InterfacePerfTable AUGMENTs the nhdpInterfacePerfTable.
MANET technology is often deployed to support communications of
emergency services or military tactical applications. In these
applications, it is imperative to maintain the proper operation of
the communications network and to protect sensitive information
related to its operation. Therefore, when implementing these
capabilities, the full use of SNMPv3 cryptographic mechanisms for
authentication and privacy is RECOMMENDED.
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.
Herberg, et al. Standards Track [Page 79]
^L
RFC 7184 The OLSRv2-MIB April 2014
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.
9. Applicability Statement
This document describes objects for configuring parameters of the
Optimized Link State Routing Protocol version 2 (OLSRv2) [RFC7181]
process on a router. This MIB module, denoted OLSRv2-MIB, also
reports state, performance information, and notifications. The
OLSRv2 protocol relies upon information gathered via the Neighborhood
Discovery Protocol [RFC6130] in order to perform its operations.
NHDP is managed via the NHDP-MIB [RFC6779].
MANET deployments can greatly differ in aspects of dynamics of the
topology, capacity, and loss rates of underlying channels, traffic
flow directions, memory and CPU capacity of routers, etc. SNMP, and
therefore this MIB module, are only applicable for a subset of MANET
deployments, in particular deployments:
o In which routers have enough memory and CPU resources to run SNMP
and expose the MIB module.
o Where a Network Management System (NMS) is defined to which
notifications are generated and from which routers can be managed.
o Where this NMS is reachable from routers in the MANET most of the
time (as notifications to the NMS and management information from
the NMS to the router will be lost when connectivity is
temporarily lost). This requires that the topology of the MANET
is only moderately dynamic.
o Where the underlying wireless channel supports enough bandwidth to
run SNMP, and where loss rates of the channel are not exhaustive.
Herberg, et al. Standards Track [Page 80]
^L
RFC 7184 The OLSRv2-MIB April 2014
Certain MANET deployments such as community networks with non-mobile
routers, dynamic topology because of changing link quality, and a
predefined gateway (that could also serve as NMS), are examples of
networks applicable for this MIB module. Other, more constrained
deployments of MANETs may not be able to run SNMP and require
different management protocols.
Some level of configuration, i.e., read-write objects, is desirable
for OLSRv2 deployments. Topology-related configuration, such as the
ability to enable OLSRv2 on new interfaces or initially configure
OLSRv2 on a router's interfaces through the
olsrv2InterfaceAdminStatus object, is critical to initial system
startup. The OLSRv2 protocol allows for some level of performance
tuning through various protocol parameters, and this MIB module
allows for configuration of those protocol parameters through read-
write objects such as the olsrv2TcHopLimit or the olsrv2FMaxJitter.
Other read-write objects allow for the control of Notification
behavior through this MIB module, e.g., the
olsrv2RoutingSetRecalculationCountThreshold object. A fuller
discussion of MANET network management applicability is to be
provided elsewhere: [MGMT-SNAP] provides a snapshot of OLSRv2-routed
MANET management as currently deployed, while [MANET-MGMT] is
intended to provide specific guidelines on MANET network management
considering the various MIB modules that have been written.
10. IANA Considerations
IANA now maintains the IANAolsrv2LinkMetricType-MIB and keeps it
synchronized with the "LINK_METRIC Address Block TLV Type Extensions"
registry at <http://www.iana.org/assignments/manet-parameters>.
The MIB modules in this document use the following IANA-assigned
OBJECT IDENTIFIER values recorded in the SMI Numbers registry:

Herberg, et al. Standards Track [Page 84]
^L
RFC 7184 The OLSRv2-MIB April 2014
LINK_METRIC_TYPE of OLSRv2 (RFC 7181).
OLSRv2 uses bidirectional additive link metrics
to determine shortest distance routes (i.e.,
routes with smallest total of link metric values).
OLSRv2 has established a registry for the LINK_METRIC_TYPEs
(denoted 'LINK_METRIC Address Block TLV Type Extensions'):
http://www.iana.org/assignments/manet-parameters/
This is done in Section 24.5 in OLSRv2 (RFC 7181).
The LINK_METRIC_TYPE (which has as corresponding
object in the MIB module olsrv2LinkMetricType)
corresponds to the type extension of
the LINK_METRIC TLV that is set up in the
'LINK_METRIC Address Block TLV Type Extensions' registry.
Whenever new link metric types are added to that registry,
IANA MUST update this textual convention accordingly.
The definition of this textual convention with the
addition of newly assigned values is published
periodically by the IANA, in either the Assigned
Numbers RFC, or some derivative of it specific to
Internet Network Management number assignments. (The
latest arrangements can be obtained by contacting the
IANA.)
Requests for new values should be made to IANA via
email (iana@iana.org)."
