Status of This Memo

This document specifies an Internet standards track protocol for the
Internet community, and requests discussion and suggestions for
improvements. Please refer to the current edition of the "Internet
Official Protocol Standards" (STD 1) for the standardization state
and status of this protocol. Distribution of this memo is unlimited.

Abstract

This memo defines a portion of the Management Information Base (MIB),
the Network Mobility (NEMO) support MIB, for use with network
management protocols in the Internet community. In particular, the
NEMO MIB will be used to monitor and control a Mobile IPv6 node with
NEMO functionality.

1. 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].

2. Overview

2.1. The Mobile IPv6 Protocol and NEMO Entities

Mobile IPv6 (MIPv6) [RFC3775] specifies a protocol that allows nodes
to remain reachable while moving around in the IPv6 Internet. The
Network Mobility (NEMO) Basic Support Protocol [RFC3963] is an
extension to the Mobile IPv6 protocol that facilitates the movement
of an entire network. The goals of Network Mobility support and
related terminology are discussed in [RFC4886] and [RFC4885],
respectively.

Typically, mobile routers implement NEMO functionality for achieving
network mobility. However, a mobile router may also function as a
mobile node. In the context of this document, an entity that
implements the NEMO protocol is a NEMO entity.

Gundavelli, et al. Standards Track [Page 2]

RFC 5488 NEMO Management Information Base April 2009

This document defines a set of managed objects (MOs) that can be used
to monitor and control NEMO entities.

2.2. Relationship to Other MIB Modules

This document focuses on the management of a NEMO entity. It is
assumed that implementations will support the ifTable from the IF-MIB
[RFC2863]. The MOBILEIPV6-MIB [RFC4295] defines the managed objects
for a mobile node. Implementations supporting both the mobile node
and NEMO functionality SHOULD implement the managed objects defined
for the NEMO entities and mobile nodes from both the MOBILEIPV6-MIB
and NEMO-MIB. The NEMO-MIB uses the textual conventions defined in
the INET-ADDRESS-MIB [RFC4001].

2.3. Terminology

The terminology used in this document is consistent with the
definitions used in the Mobile IPv6 protocol specification [RFC3775]
and the NEMO Basic Support specification [RFC3963].

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 BCP
14, RFC 2119 [RFC2119].

2.4. MIB Design

The NEMO MIB comprises the following groups of definitions:

nemoCore: a generic group containing objects that are common to all
NEMO entities.

nemoHa: this group models the home agent service. It is composed of
objects specific to the services and associated advertisement
parameters offered by the home agent on each of its links. It
also contains objects pertaining to the maintenance of the home
agent list on each of the links on which the service is offered.

nemoMr: this group models the mobile router service. It is composed
of objects specific to the Dynamic Home Agent discovery function
and related parameters. It also contains objects that record the
movement of the mobile router.

nemoNotifications: defines the set of notifications that will be used
to asynchronously monitor the NEMO entities.

Gundavelli, et al. Standards Track [Page 3]

RFC 5488 NEMO Management Information Base April 2009

The tables contained in the above groups are as follows:

nemoBindingCacheTable: models the Binding Cache on the home agent and
correspondent node. It contains details of the Binding Update
requests that have been received and accepted.

nemoMrEgressIfTable: contains information on the configured egress
interfaces.

nemoMrBLTable: models the Binding Update List on the mobile router.
It contains information about the registration requests sent by
the mobile router and the corresponding results.

nemoHaCounterTable: contains registration statistics for all mobile
routers registered with the home agent.

nemoHaMobileNetworkPrefixTable: contains the list of the mobile
network prefixes that are maintained by the home agent.

"The compliance statement for SNMP entities that
implement the NEMO-MIB with support for monitoring
of the home agent functionality, specifically the
home-agent-registration-related statistics.

There are a number of INDEX objects that cannot be
represented in the form of OBJECT clauses in SMIv2,
but for which there are compliance requirements,
expressed in OBJECT-clause form in this description:

4. IANA Considerations

IANA has assigned a base arc in the mib-2 (Standards Track) OID tree
for the 'nemoMIB' (184).

5. Security Considerations

There are a number of management objects defined in this MIB module
with a MAX-ACCESS clause of read-write. 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:

nemoStatus: The value of this object is used to enable or disable the
NEMO functionality on a NEMO entity. Access to this MO may be
abused to disrupt the communication that depends on NEMO.

nemoMrPrefixRegMode: The value of this object is used to control the
mode in which mobile network prefixes will be registered with the
home agent. Access to this object may be abused to disrupt the
setting up of mobile network prefixes.

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:

nemoHaMobileNetworkPrefixType

nemoHaMobileNetworkPrefix

nemoHaMobileNetworkPrefixLength:

The above address-related objects may be considered to be
particularly sensitive and/or private. The mobile-network-
prefix-related objects reveal the configuration of the mobile
router and, as such, may be considered to be sensitive.

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
in this MIB module.

Gundavelli, et al. Standards Track [Page 41]

RFC 5488 NEMO Management Information Base April 2009

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.
