Abstract

This memo defines a portion of the Management Information Base (MIB), the Mobile-IPv6 MIB, for use with network management protocols in the Internet community. In particular, the Mobile-IPv6 MIB will be used to monitor and control the mobile node, home agent, and correspondent node functions of a Mobile IPv6 (MIPv6) entity.

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 Entities

Mobile IPv6 (MIPv6) [RFC3775] specifies a protocol that allows nodes to remain reachable while moving around in the IPv6 Internet. An entity that implements the MIPv6 protocol is a MIPv6 entity. There are three types of entities envisaged by the MIPv6 protocol.

mobile node (MN): A node that can change its point of attachment from one link to another, while still being reachable via its home address.

correspondent node (CN): A peer node with which a mobile node is communicating. The correspondent node may be either mobile or stationary. (Note that a correspondent node does not necessarily require MIPv6 support.)

home agent (HA): A router on a mobile node's home link with which the mobile node has registered its current care-of address. While the mobile node is away from home, the home agent intercepts packets on the home link destined to the mobile node's home address, encapsulates them, and routes them to the mobile node's registered care-of address.

This document defines a set of managed objects (MOs) that can be used to monitor and control MIPv6 entities.

2.2. Terminology

The terminology used in this document is consistent with the definitions used in Mobile IPv6 protocol specification [RFC3775].

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].

3. Mobile IPv6 Monitoring and Control Requirements

For managing a MIPv6 entity it is necessary to monitor the following:

       o capabilities of MIPv6 entities
       o traffic due to MIPv6
       o binding-related statistics (at home agent, correspondent
         node, and mobile node)
       o binding details (at home agent and correspondent node)
       o history of Binding Updates (at home agent, correspondent
         node, and mobile node)

The MIPv6 protocol document stipulates that several MIPv6-related parameters should be manually configurable. The MIPv6 MIB should define managed objects that can be used to configure the related parameters, for example:

       o the preference value the home agent will use in Router
         Advertisements;
       o the lifetime value the home agent will use in Router
         Advertisements;
       o whether a home agent will send ICMP Mobile Prefix
         Advertisements to mobile nodes;
       o whether a home agent will respond to ICMP Mobile Prefix
         Solicitation messages from mobile nodes; and
       o whether a home agent will process multicast group membership
         control messages from mobile nodes.

4. MIB Design

The basic principle has been to keep the MIB as simple as possible and at the same time to make it effective enough so that the essential needs of monitoring and control are met. It is envisaged that wherever possible existing MIBs will be used (e.g., IPSec MIB, Neighbor Discovery MIB, Tunnel MIB [RFC4087]) for monitor and control of MIPv6 entities.

It is assumed that the Mobile IPv6 Management Information Base (MOBILEIPV6-MIB) will always be implemented in conjunction with the IPv6-capable version of the IP-MIB [RFC4293]. The MOBILEIPV6-MIB uses the textual conventions defined in the INET-ADDRESS-MIB [RFC4001].

The Mobile-IPv6 MIB is composed of the following groups of definitions:

       - mip6Core: a generic group containing objects that are
         common to all the Mobile IPv6 entities.
       - mip6Ha: 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.
       - mip6Mn: this group models the mobile node 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 node.
       - mip6Cn: models the correspondent node and is primarily
         scoped to its participation in the Return Routability
         procedure for achieving Route Optimization triggered by
         the mobile node.
       - mip6Notifications: defines the set of notifications that
         will be used to asynchronously monitor the Mobile IPv6
         entities.

The tables contained in the above groups are as follows:

       mip6BindingCacheTable   : 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.
       mip6BindingHistoryTable : tracks the history of the binding
                                 cache.
       mip6NodeTrafficTable    : the mobile node-wise traffic counters.
       
       mip6MnHomeAddressTable  : contains all the home addresses
                                 pertaining to the mobile node and
                                 the corresponding registration status.
       mip6MnBLTable           : models the Binding Update List on the
                                 mobile node.  It contains information
                                 about the registration requests sent
                                 by the mobile node and the
                                 corresponding results.
       mip6CnCounterTable      : contains the mobile node-wise
                                 registration statistics.
       mip6HaConfTable         : contains the configurable
                                 advertisement parameters for all the
                                 interfaces on which the home agent
                                 service is advertised.
       mip6HaCounterTable      : contains registration statistics
                                 for all mobile nodes registered
                                 with the home agent.
       mip6HaListTable         : contains the list of all routers
                                 that are acting as home agents on
                                 each of the interfaces on which
                                 the home agent service is offered
                                 by this router.
       mip6HaGlAddrTable       : contains the global addresses of
                                 the home agents.

6. 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 the corresponding sensitivity/vulnerability:

        mip6Status:  The value of this object is used to enable or
                     disable the MIPv6 functionality on a MIPv6 entity.
                     Access to this MO may be abused to disrupt the
                     MIPv6 communication.
        mip6HaAdvPreference: Access to this object may be abused to
                     force MNs into selecting the wrong HA.
        mip6HaAdvLifetime: Access to this object may be abused to set
                     the advertised lifetime to incorrect values.  That
                     will have an adverse impact on the MIPv6
                     communication.
        mip6BindingAdminStatus: The value of this object is used to
                     control the status of a Binding Cache entry.
                     Access to this object may be abused to deny Mobile
                     IPv6 connectivity to a legitimate user or to
                     grant Mobile IPv6 connectivity to an illegal user.
        mip6HaPrefixAdv: The value of this object indicates whether
                     the home agent will send ICMP Mobile Prefix
                     Advertisements to the mobile node.
                     Access to this object may be abused to send
                     unwanted/wrong prefix information or to deny the
                     mobile node from receiving information about the
                     changes in the home prefixes.
                     This may result in disruption of the Mobile IPv6
                     connectivity.
        mip6HaPrefixSolicitation: The value of this object indicates
                     whether the home agent should respond to ICMP
                     Mobile Prefix Solicitation messages from a mobile
                     node.  Access to this object may be abused to deny
                     the mobile node information about its home prefix.
                     This may result in disruption of the Mobile IPv6
                     connectivity.
        mip6HaMCastCtlMsgSupport: The value of this object decides
                     whether the home agent should process the
                     multicast group membership control messages it
                     receives from mobile nodes.  Access to this object
                     may be used to subvert administrate policy on
                     multicasting or to disrupt the multicast
                     communication with the mobile node.

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:

The address-related objects in this MIB may be considered to be particularly sensitive and/or private. The care-of-address-related objects reveal the location and movement of the mobile node. This information may be considered to be private and sensitive and must be carefully handled.

mip6BindingHstCOAType
mip6BindingHstCOA
mip6MnBLCOAType
mip6MnBLCOA

The mobile node's home-address- and home-agent-related information may be considered to be sensitive too as these may provide clues to a malicious party on ways to disrupt the mobile nodes communication channels.

mip6BindingHstHomeAddressType,
mip6BindingHstHomeAddress,
mip6MnHomeAddressType,
mip6MnHomeAddress

The correspondent node's address-related MOs will reveal the nodes with whom the mobile node is corresponding. This information may be considered private and sensitive.

mip6MnBLNodeAddressType,
mip6MnBLNodeAddress

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.

It is RECOMMENDED that implementors 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.

7. IANA Considerations

IANA has assigned a base arc in the 'mib-2' (standards track) OID tree for the 'mip6MIB' MODULE-IDENTITY defined in the Mobile-IPv6 MIB. The mib-2 number is 133 for mip6MIB.
