The Definitions of Managed Objects for IP Mobility Support
using SMIv2
 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 the Management Information Base (MIB) for use with
network management protocols in TCP/IP-based internets. In
particular, it describes managed objects used for managing the Mobile
Node, Foreign Agent and Home Agent of the Mobile IP Protocol.

RFC 2006 Mobile IP MIB Definition using SMIv2 October 1996
1. The SNMP Network Management Framework
The Internet-standard Network Management Framework presently consists
of three major components. They are:
The SMI, described in RFC 1902 [1] - the mechanisms used for
describing and naming objects for the purpose of management.
The MIB-II, STD 17, RFC 1213 [2] - the core set of managed objects
for the Internet suite of protocols.
The protocol, RFC 1157 [3] and/or RFC 1905 [4], - the protocol for
accessing managed objects.
The Framework permits new objects to be defined for the purpose of
experimentation and evaluation.
2. Objects
2.1. Object Definitions
Managed objects are accessed via a virtual information store, termed
the Management Information Base or MIB. Objects in the MIB are
defined using the subset of Abstract Syntax Notation One (ASN.1)
defined in the SMI. In particular, each object type is named by an
OBJECT IDENTIFIER, an administratively assigned name. The object
type together with an object instance serves to uniquely identify a
specific instantiation of the object. For human convenience, we
often use a textual string, termed the descriptor, to refer to the
object type.
3. Overview
3.1. Object Selection Criteria
To be consistent with IAB directives and good engineering practice,
the authors have applied some criteria to select managed objects for
the Mobile IP Protocol.
(1) Partition management functionality among the Mobile Node, Home
Agent, and Foreign Agent according to the partitioning seen in
the Mobile IP Protocol.
(2) Require that objects be essential for either fault or
configuration management.
(3) Limit the total number of objects.
Cong, Hamlen & Perkins Standards Track PAGE 2
RFC 2006 Mobile IP MIB Definition using SMIv2 October 1996
(4) Exclude objects which are simply derivable from others in this or
other MIBs.
3.2. Structure of the Mobile IP
This section describes the basic model of Mobile IP used in
developing the Mobile IP MIB. This information should be useful to
the implementor in understanding some of the basic design decisions
of the MIB.
The Mobile IP Protocol introduces these new funtional entities:
Mobile Node
A host or router that changes its point of attachment from one
network or subnetwork to another. A mobile node may change its
location without losing connectivity and without changing its IP
address; it may continue to communicate with other Internet nodes
at any location using its (constant) IP address, assuming link-
layer connectivity to a point of attachment is available.
Home Agent
A router on a mobile node's home network which tunnels packets for
delivery to the mobile node when it is away from home, and
maintains current location information for the mobile node.
Foreign Agent
A router on a mobile node's visited network which provides routing
services to the mobile node while registered. The foreign agent
detunnels and delivers packets to the mobile node that were
tunneled by the mobile node's home agent. For datagrams sent by a
mobile node, the foreign agent may serve as a default router for
registered mobile nodes.
This document specifies the objects used in managing these entities;
namely, the Mobile Node, the Home Agent, and the Foreign Agent.
Cong, Hamlen & Perkins Standards Track PAGE 3
RFC 2006 Mobile IP MIB Definition using SMIv2 October 1996
3.3. MIB Groups
Objects in this MIB are arranged into groups. Each group is
organized as a set of related objects. The overall structure and the
relationship between groups and the Mobile IP entities are shown
below:
Groups Mobile Node Foreign Agent Home Agent
mipSystemGroup X X X
mipSecAssociationGroup X X X
mipSecViolationGroup X X X
mnSystemGroup X
mnDiscoveryGroup X
mnRegistrationGroup X
maAdvertisementGroup X X

5. Acknowledgments
This document was produced by the Mobile IP working group. The
editors wish to thank Bob Stewart (Cisco Systems), for his help in
converting from SNMPv1 to SNMPv2. We also want to thank Jim Solomon,
for his encouragement, patience, and help. Thanks to Fredrick Tarberg
and Fredrik Broman (KTH) for their initial efforts in defining a
Mobile IP MIB. Thanks to Frank Kastenholz (FTP Software) for his
comments on the initial MIB from KTH. Thanks to Gerald Maguire (KTH)
for his comments on the first version of this MIB. Thanks to Mike
Roels (Motorola) for his help in testing this MIB.
6. Security Considerations
The Mobile IP MIB affords the network operator the ability to
configure and control the Mobile IP links of a particular system,
including the Mobile IP authentication protocols, and shared secret
key. This represents a security risk.
These risks are addressed in the following manners:
(1) All variables which represent a significant security risk are
placed in separate MIB Groups. By providing Agent Capability
Statements, the implementor of the MIB may elect not to
implement these groups.
(2) The MIB allows the manager station to create the security
association for Mobile IP entities. However, the agent should
always return 0 length octet string when the manager station
retrieves the shared security key in the mipSecAssocTable. In
this way, the Mobile IP entities can prevent the key leaking
from SNMP GET, GET-NEXT, or GET-BULK requests.
(3) The MIB defines a trap for Mobile IP entities to send a
notification to the manager station if there is a security
violation. In this way, the operator can notice the source of
an intruder.
(4) The MIB also defines a table to log the security violations
in the Mobile IP entities. The manager station can retrieve
this log to analyze the security violation instances in the
Cong, Hamlen & Perkins Standards Track PAGE 49
RFC 2006 Mobile IP MIB Definition using SMIv2 October 1996
system.
Thus, in order to preserve the integrity, security and privacy of the
Mobile IP security features, an implementation SHOULD allow access to
this MIB only via SNMPv2 and with other security enhancement such as
SNMPv2Sec. The other way to access this information is in concert
with the IP security protocols (IP Authentication Header and IP
Encapsulating Security Payload).
