1. Introduction

 This document defines a portion of the Management Information Base
 (MIB) for use with network management protocols in the Internet
 community.  In particular, it describes objects for configuring
 parameters of the Neighborhood Discovery Protocol (NHDP) [RFC6130]
 process on a router.  The MIB module defined in this document,
 denoted NHDP-MIB, also reports state, performance information, and
 notifications about NHDP.  This additional state and performance
 information is useful to troubleshoot problems and performance issues
 during neighbor discovery.

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. 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

 [RFC6130] allows a router to discover and track topological
 information of routers up to two hops away by virtue of exchanging
 HELLO messages.  This information is useful for routers running
 various routing and multicast flooding protocols developed within the
 IETF MANET Working Group.

Herberg, et al. Standards Track [Page 3] RFC 6779 The NHDP-MIB October 2012

4.1. Terms

 The following definitions apply throughout this document:
 o  Notification Objects - triggers and associated notification
    messages allowing for asynchronous tracking of pre-defined events
    on the managed router.
 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 NHDP instance in the router.
 o  Performance Objects - automatically generated values that help an
    administrator or automated tool to assess the performance of the
    NHDP instance on the router and the overall discovery performance
    within the Mobile Ad Hoc Network (MANET).

4.2. Notation

 The same notations as defined in [RFC6130] are used throughout this
 document.

5. Structure of the MIB Module

 This section presents the structure of the NHDP-MIB module.  The MIB
 module is arranged into the following structure:
 o  nhdpNotifications - objects defining NHDP-MIB notifications.
 o  nhdpObjects - defining objects within this MIB module.  The
    objects are arranged into the following groups:
  • Configuration Group - defining objects related to the

configuration of the NHDP instance on the router.

  • State Group - defining objects that reflect the current state

of the NHDP instance running on the router.

  • Performance Group - defining objects that are useful to a

management station when characterizing the performance of NHDP

       on the router and in the MANET.
 o  nhdpConformance - defining the minimal and maximal conformance
    requirements for implementations of this MIB module.

Herberg, et al. Standards Track [Page 4] RFC 6779 The NHDP-MIB October 2012

5.1. Notifications

 This section describes the use of notifications and mechanisms to
 enhance the ability to manage NHDP routing domains.

5.1.1. Introduction

 Notifications can be emitted by a router running an instance of this
 specification as a reaction to a specific event.  This allows a
 network manager to efficiently determine the source of problems or
 significant changes of configuration or topology, instead of polling
 a possibly large number of routers.

5.1.2. Notification Generation

 When an exception event occurs, the application notifies the local
 agent, which sends a notification to the appropriate SNMP management
 stations.  The message includes the notification type and may include
 a list of notification-specific variables.  Section 7 contains the
 notification definitions, which includes the variable lists.  At
 least one IP address of the router that originates the notification
 is included in the variable list so that the network manager may
 determine the source of the notification.

5.1.3. Limiting Frequency of Notifications

 To limit the frequency of notifications, the following additional
 mechanisms are suggested, similar to those in [RFC4750].

5.1.3.1. Ignoring Initial Activity

 The majority of critical events occur when NHDP is first enabled on a
 router, at which time the symmetric neighbors and two-hop neighbors
 of the router are discovered.  During this initial period, a
 potential flood of notifications is unnecessary since the events are
 expected.  To avoid unnecessary notifications, a router SHOULD NOT
 originate expected notifications until a certain time interval has
 elapsed, which is to be predefined by the network manager.  It is
 RECOMMENDED that this time interval is at least 3 x
 nhdpHelloInterval, so that symmetric neighbors are discovered.  The
 suppression window for notifications is started when the nhdpIfStatus
 transitions from its default value of 'false(2)' to 'true(1)'.

5.1.3.2. Throttling Notifications

 The mechanism for throttling the notifications is the same as in
 [RFC4750] (i.e., the number of transmitted notifications per time is
 bounded).

Herberg, et al. Standards Track [Page 5] RFC 6779 The NHDP-MIB October 2012

 Appropriate values for the window time and upper bound are to be
 selected by the network manager and depend on the deployment of the
 MANET.  If NHDP is deployed on a lossy, wireless medium, sending too
 many notifications in a short time interval may lead to collisions
 and dropped packets.  In particular, in dense deployments of routers
 running NHDP (i.e., where each router has many neighbors), a change
 of the local topology may trigger many notifications at the same
 time.  [RFC4750] recommends "7 traps with a window time of 10
 seconds" as the upper bound.  As NHDP is expected to be deployed in
 more lossy channels than OSPF, it is RECOMMENDED to choose a lower
 threshold for the number of notifications per time than that.
 Specifically, it is RECOMMENDED that the threshold value for the
 objects reflecting the change be set to a value of '10' and the
 DEFAULT values for these objects within the Notifications Group be
 set to this value.  Further, a time window for the change objects is
 defined within this MIB module.  It is RECOMMENDED that if the number
 of occurrences exceeds the change threshold within the previous
 change window, then the notification is to be sent.  Furthermore, it
 is RECOMMENDED that the value for this window be set to at least 5
 times the nhdpHelloInterval.
 The following objects are used to define the thresholds and time
 windows for specific notifications defined in the NHDP-MIB module:
 nhdpNbrStateChangeThreshold, nhdpNbrStateChangeWindow,
 nhdp2HopNbrStateChangeThreshold, and nhdp2HopNbrStateChangeWindow.

5.1.3.3. One Notification per Event

 Similar to the mechanism in [RFC4750], only one notification is sent
 per event.

5.2. The Configuration Group

 The router running NHDP is configured with a set of controls.  The
 authoritative list of configuration controls within the NHDP-MIB
 module are found within the MIB module itself.  Generally, an attempt
 was made in developing the NHDP-MIB module to support all
 configuration objects defined in [RFC6130].  For all of the
 configuration parameters, the same constraints and default values of
 these parameters as defined in [RFC6130] are followed.  Refer to
 [RFC5148] for guidance on setting jitter-related parameters, e.g.,
 nhdpMaxJitter.

Herberg, et al. Standards Track [Page 6] RFC 6779 The NHDP-MIB October 2012

5.3. The State Group

 The State Group reports current state information of a router running
 NHDP.  The NHDP-MIB State Group tables were designed to contain the
 complete set of state information defined within the information
 bases specified in Sections 6, 7, and 8 of [RFC6130].
 Two constructs, i.e., TEXTUAL-CONVENTIONs, are defined to support the
 tables in the State Group.  NHDP stores and indexes information
 through sets of (dynamically defined) addresses, i.e., address sets.
 Within SMIv2, it is not possible to index tables with variably
 defined address sets.  Hence, these TEXTUAL-CONVENTIONs are defined
 to provide a local mapping between NHDP-managed address sets and
 SMIv2 table indexing.  These constructs are the NeighborIfIndex and
 NeighborRouterIndex.  These are locally (to the router) defined,
 unique identifiers of virtual neighbors and neighbor interfaces.  Due
 to the nature of NHDP, the local router may have identified distinct
 address sets but is not able to associate these as a single
 interface.  Hence, two or more NeighborIfIndexes pointing to multiple
 distinct address sets may, in fact, be related to a common neighbor
 interface.  This ambiguity may also hold with respect to the
 assignment of the NeighborRouterIndex.  The local MIB agent is
 responsible for managing, aggregating, and retiring the defined
 indexes and for updating MIB tables using these indexes as the local
 router learns more about its neighbors' topologies.  These constructs
 are used to define indexes to the appropriate State Group tables and
 to correlate table entries to address sets, virtual neighbor
 interfaces, and virtual neighbors within the MANET.

5.4. The Performance Group

 The Performance Group reports values relevant to system performance.
 Unstable neighbors or 2-hop neighbors and frequent changes of sets
 can have a negative influence on the performance of NHDP.  This MIB
 module defines several objects that can be polled in order to, e.g.,
 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].

5.5. Tables and Indexing

 The NHDP-MIB module contains a number of tables that record data
 related to:
 o  the local router,
 o  a local MANET interface on the router,

Herberg, et al. Standards Track [Page 7] RFC 6779 The NHDP-MIB October 2012

 o  other routers that are 1 hop removed from the local router,
 o  interfaces on other routers that are 1 hop removed from the local
    router, and
 o  other routers that are 2 hops removed from the local router.
 The NHDP-MIB module's tables are indexed via the following
 constructs:
 o  nhdpIfIndex - the IfIndex of the local router on which NHDP is
    configured.
 o  nhdpDiscIfIndex - a locally managed index representing a known
    interface on a neighboring router.
 o  nhdpDiscRouterIndex - a locally managed index representing an ID
    of a known neighboring router.
 These tables and their indexing are:
 o  nhdpInterfaceTable - describes the configuration of the interfaces
    of this router.  This table has INDEX { nhdpIfIndex }.
 o  nhdpLibLocalIfSetTable - records all network addresses that are
    defined as local interface network addresses on this router.  This
    table has INDEX { nhdpLibLocalIfSetIndex }.
 o  nhdpLibRemovedIfAddrSetTable - records network addresses that were
    recently used as local interface network addresses on this router
    but have been removed.  This table has INDEX
    { nhdpLibRemovedIfAddrSetIndex }.
 o  nhdpInterfaceStateTable - records state information related to
    specific interfaces of this router.  This table has INDEX
    { nhdpIfIndex }.
 o  nhdpDiscIfSetTable - includes the nhdpDiscRouterIndex of the
    discovered router, the nhdpDiscIfIndex of the discovered
    interface, and the current set of addresses associated with this
    neighbor interface.  This table has INDEX { nhdpDiscIfSetIndex }.
 o  nhdpIibLinkSetTable - for each local interface, records all links
    belonging to other routers that are, or recently were, 1-hop
    neighbors to this router.  This table has INDEX { nhdpIfIndex,
    nhdpDiscIfIndex }.

Herberg, et al. Standards Track [Page 8] RFC 6779 The NHDP-MIB October 2012

 o  nhdpIib2HopSetTable - for each local interface, records network
    addresses (one at a time) of symmetric 2-hop neighbors and the
    symmetric links to symmetric 1-hop neighbors of this router
    through which these symmetric 2-hop neighbors can be reached.
    This table has INDEX { nhdpIfIndex, nhdpDiscIfIndex,
    nhdpIib2HopSetIpAddressType, nhdpIib2HopSetIpAddress }.
 o  nhdpNibNeighborSetTable - records all network addresses of each
    1-hop neighbor to this router.  This table has INDEX
    { nhdpDiscRouterIndex }.
 o  nhdpNibLostNeighborSetTable - records network addresses of other
    routers that were recently symmetric 1-hop neighbors to this
    router but are now advertised as lost.  This table has INDEX
    { nhdpDiscRouterIndex }.
 o  nhdpInterfacePerfTable - records performance objects that are
    measured for each local NHDP interface on this router.  This table
    has INDEX { nhdpIfIndex }.
 o  nhdpDiscIfSetPerfTable - records performance objects that are
    measured for each discovered interface of a neighbor of this
    router.  This table has INDEX { nhdpDiscIfIndex }.
 o  nhdpDiscNeighborSetPerfTable - records performance objects that
    are measured for discovered neighbors of this router.  This table
    has INDEX { nhdpDiscRouterIndex }.
 o  nhdpIib2HopSetPerfTable - records performance objects that are
    measured for discovered 2-hop neighbors of this router.  This
    table has INDEX { nhdpDiscRouterIndex }.

6. Relationship to Other MIB Modules

 This section specifies the relationship of the MIB module 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 NHDP-MIB
 module does not duplicate those objects.

Herberg, et al. Standards Track [Page 9] RFC 6779 The NHDP-MIB October 2012

6.2. Relationship to Routing Protocol MIB Modules Relying on the

    NHDP-MIB Module
 [RFC6130] allows routing protocols to rely on the neighborhood
 information that is discovered by means of HELLO message exchange.
 In order to allow for troubleshooting, fault isolation, and
 management of such routing protocols through a routing protocol MIB
 module, it may be desired to align the State Group tables of the
 NHDP-MIB module and the routing protocol MIB module.  This is
 accomplished through the definition of two TEXTUAL-CONVENTIONs in the
 NHDP-MIB module: the NeighborIfIndex and the NeighborRouterIndex.
 These object types are used to develop indexes into common NHDP-MIB
 module and routing protocol State Group tables.  These objects are
 locally significant but should be locally common to the NHDP-MIB
 module and the routing protocol MIB module implemented on a common
 networked router.  This will allow for improved cross-referencing of
 information across the two MIB modules.

6.3. MIB Modules Required for IMPORTS

 The following NHDP-MIB module IMPORTS objects from SNMPv2-SMI
 [RFC2578], SNMPv2-TC [RFC2579], SNMPv2-CONF [RFC2580], IF-MIB
 [RFC2863], INET-ADDRESS-MIB [RFC4001], and FLOAT-TC-MIB [RFC6340].

     same interface of a neighbor or to two different
     interfaces.  As the local router gains more
     knowledge of its neighbors, its local view may change, and
     this table will be updated to reflect the local router's
     current understanding, associating address sets to neighbor
     interfaces.  The local router identifies a virtual neighbor
     interface through the receipt of address lists advertised
     through an NHDP HELLO message.
     All objects of type NeighborIfIndex are assigned by the agent
     out of a common number space.

Herberg, et al. Standards Track [Page 13] RFC 6779 The NHDP-MIB October 2012

     The value for each discovered virtual neighbor
     interface may not remain constant from
     one re-initialization of the entity's network management
     agent to the next re-initialization.  If the
     local router gains information associating two virtual
     interfaces on a neighbor as a common interface,
     then the agent MUST aggregate the two address sets to
     a single index chosen from the set of aggregated indexes,
     and it MUST update all tables in this
     MIB module that are indexed by indexes
     of type NeighborIfIndex.  It MAY then reuse freed
     index values following the next agent restart.
     The specific value is meaningful only within a given SNMP
     entity."

 DESCRIPTION
    "An arbitrary, locally unique identifier associated with a
     virtual discovered neighbor (one or two hop).  Due to the
     nature of NHDP, the local router may identify
     multiple virtual neighbors that, in fact, are one and
     the same.  Neighbors that are two hops away with more than
     one advertised address will exhibit this behavior.  As the
     local router's knowledge of its neighbors' topology
     increases, the local router will be able to associate
     multiple virtual neighbor indexes into a single virtual
     neighbor index chosen from the set of aggregated indexes;
     it MUST update all tables in this MIB module indexed by these
     indexes, and it MAY reuse the freed indexes following the
     next agent re-initialization.
     All objects of type NeighborRouterIndex are assigned by
     the agent out of a common number space.
     The NeighborRouterIndex defines a discovered NHDP peer
     virtual neighbor of the local router.
     The value for each discovered virtual neighbor index MUST
     remain constant at least from one re-initialization of
     the entity's network management agent to the next
     re-initialization, except if an application is deleted
     and re-created.
     The specific value is meaningful only within a given SNMP
     entity.  A NeighborRouterIndex value MUST not be reused

        As such, this table 'sparse augments' the ifTable

        operate over this interface.  The interface is
        identified by the ifIndex from the interfaces
        group defined in the Interfaces Group MIB module.
        A conceptual row in this table exists if and only
        if either a manager has explicitly created the row
        or there is an interface on the managed device
        that supports and runs NHDP.
        The manager can create a row by setting
        rowStatus to 'createAndGo' or 'createAndWait'.
        Row objects having associated DEFVAL clauses are
        automatically defined by the agent with these
        values during row creation, unless the manager
        explicitly defines these object values during the

        this object has no effect on whether other

        modified.
        An entry may not exist in the 'active(1)' state unless all
        objects in the entry have a defined appropriate value.  For
        objects with DEFVAL clauses, the management station
        does not need to specify the value of this object in order
        for the row to transit to the 'active(1)' state; the default
        value for this object is used.  For objects that do not
        have DEFVAL clauses, then the network manager MUST
        specify the value of this object prior to this row
        transitioning to the 'active(1)' state.
        When this object transitions to 'active(1)', all objects
        in this row SHOULD be written to non-volatile (stable)
        storage.  Read-create objects in this row MAY be modified.
        When an object in a row with nhdpIfRowStatus of 'active(1)'
        is changed, then the updated value MUST be reflected in NHDP,
        and this new object value MUST be written to non-volatile
        storage.
        If the value of this object is not equal to 'active(1)',
        all associated entries in the nhdpLibLocalIfSetTable,

        the nhdpInterfaceTable.  The local interface
        is defined by the nhdpIfIndex.

        lengths (in order to determine the network addresses
        related to the interface).
        A conceptual row in this table exists if and only
        if a manager has explicitly created the row.  The
        manager can create a row by setting rowStatus
        to 'createAndGo' or 'createAndWait'.
        Further guidance on the addition or removal of
        local addresses and network addresses is found
        in Section 9 of RFC 6130."

8. Security Considerations

 This MIB module defines objects for the configuration, monitoring,
 and notification of the Neighborhood Discovery Protocol [RFC6130].
 NHDP allows routers to acquire topological information up to two hops
 away by virtue of exchanging HELLO messages.  The information
 acquired by NHDP may be used by routing protocols.  The neighborhood
 information, exchanged between routers using NHDP, serves these
 routing protocols as a baseline for calculating paths to all
 destinations in the MANET, relay set selection for network-wide
 transmissions, etc.
 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  nhdpIfStatus - This writable object turns on or off the NHDP
    process for the specified interface.  If disabled, higher-level
    protocol functions, e.g., routing, would fail, causing network-
    wide disruptions.
 o  nhdpHelloInterval, nhdpHelloMinInterval, and nhdpRefreshInterval -
    These writable objects control the rate at which HELLO messages
    are sent on an interface.  If set at too high a rate, this could
    represent a form of denial-of-service (DoS) attack by overloading
    interface resources.
 o  nhdpHystAcceptQuality, nhdpHystRejectQuality, nhdpInitialQuality,
    and nhdpInitialPending - These writable objects affect the
    perceived quality of the NHDP links and hence the overall
    stability of the network.  If improperly set, these settings could
    result in network-wide disruptions.
 o  nhdpInterfaceTable - This table contains writable objects that
    affect the overall performance and stability of the NHDP process.
    Failure of the NHDP process would result in network-wide failure.
    Particularly sensitive objects from this table are discussed in
    the previous list items.  This is the only table in the NHDP-MIB
    module with writable objects.
 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 62] RFC 6779 The NHDP-MIB October 2012

 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  nhdpDiscIfSetTable - The object contains information on discovered
    neighbors, specifically their IP address in the
    nhdpDiscIfSetIpAddr object.  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.  This
    object is the index into the table and has a MAX-ACCESS of 'not-
    accessible'.  However, this information can be exposed using SNMP
    operations.
 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, it is RECOMMENDED to provide
 support for the Transport Security Model (TSM) [RFC5591] in
 combination with TLS/DTLS [RFC6353].
 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 MUST provide the security features described by the
 SNMPv3 framework (see [RFC3410]), including 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
 Neighborhood Discovery Protocol [RFC6130] process on a router.  This
 MIB module, denoted NHDP-MIB, also reports state, performance
 information, and notifications.  This section provides some examples
 of how this MIB module can be used in MANET network deployments.  A
 fuller discussion of MANET network management use cases and
 challenges will be provided elsewhere.
 NHDP is designed to allow routers to automatically discover and track
 routers one hop remote (denoted "neighbors") and routers two hops
 remote (denoted "two-hop neighbors").  This information is used by
 other MANET protocols in operation on the router to perform routing,
 multicast forwarding, and other functions with ad hoc and mobile
 networks.  In the following, three example scenarios are listed where
 this MIB module is useful:
 o  For a Parking Lot Initial Configuration Situation - It is common
    for the vehicles comprising the MANET being forward deployed at a
    remote location, e.g., the site of a natural disaster, to be off-
    loaded in a parking lot where an initial configuration of the
    networking devices is performed.  The configuration is loaded into
    the devices from a fixed location Network Operation Center (NOC)
    at the parking lot, and the vehicles are stationary at the parking
    lot while the configuration changes are made.  Standards-based
    methods for configuration management from the co-located NOC are
    necessary for this deployment option.
 o  For Mobile Vehicles with Low-Bandwidth Satellite Link to a Fixed
    NOC - Here, the vehicles carrying the MANET routers carry multiple
    wireless interfaces, one of which is a relatively low-bandwidth,
    on-the-move satellite connection that interconnects a fix NOC to
    the nodes of the MANET.  Standards-based methods for monitoring
    and fault management from the fixed NOC are necessary for this
    deployment option.
 o  For Fixed NOC and Mobile Local Manager in Larger Vehicles - for
    larger vehicles, a hierarchical network management arrangement is
    useful.  Centralized network management is performed from a fixed
    NOC while local management is performed locally from within the
    vehicles.  Standards-based methods for configuration, monitoring,
    and fault management are necessary for this deployment option.
