Internet-Draft The DYMO MIB February 2008
1. Introduction
This memo 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 aspects of the
Dynamic MANET On-demand (DYMO) routing [I-D:ietf-manet-dymo] process
on a router. The DYMO MIB also reports state information, i.e.,
Routing Information Base (RIB) entries, performance metrics, i.e.,
counter of the number Routing Messages, and notifications. In
addition to configuration, this additional state and performance
information is useful to management stations troubleshooting routing
problems.
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", "MAY", and "OPTIONAL" in this
document are to be interpreted as described in RFC 2119 [RFC2119].
4. Overview
The DYMO routing protocol allows routers in a Mobile Ad-Hoc network
(MANET) setting to discover forwarding paths through the network.
The DYMO routing protocol is an On-Demand protocol in the sense that
it only discovers paths when there is end system data traffic to
transmit. When a Source Node (SN) has traffic to send to a Target
Node (TN), the SN floods the MANET with a route_request (RREQ)
message containing the SN and TN addresses. Intermediate Nodes (IN)
rebroadcast the RREQ message, appending path information as the
message propagates throughout the MANET. When the RREQ message
reaches the TN, it replies with a route_reply (RREP) message to the
SN. Once the SN receives the RREP message from the TN, path
information in the form of path entries in the Source, Intermediate
Cole & Chakeres Expires August 21, 2008 [Page 3]
Internet-Draft The DYMO MIB February 2008
and Target nodes' Routing Information Base (RIB) is embedded and
affords packet forwarding of the data packets. Further, off-path
forwarding information towards the SN is embedded as the RREQ
messages propagate throughout the MANET.
As nodes move about, links to next hop nodes along routing paths will
break. In this case intermediate nodes can issue route_error (RERR)
messages to notify nodes relying on the broken forwarding path to
discover new paths. Hence, DYMO nodes are required to monitor the
availability of next hop links being used in forwarding paths. This
may be accomplished via the Next Hop Discovery Protocol (NHDP) [I-D:
ietf-manet-nhdp].
Routers can be configured to run the DYMO routing protocol over all
or a subset of local interfaces. Further, DYMO routers can be
configured to trigger RREP messages based upon receiving any data
destine to all unknown TN addresses or only to a subset of addresses.
DYMO routers can act as proxy, gateway nodes between DYMO routing
domains and non-DYMO routing domains. Finally, the DYMO protocol
process can be tuned through a set of configurable settings. Hence,
DYMO routers are configured to maintain:
o A list of potential DYMO target addresses for route discovery,
o A list of DYMO-enabled local interfaces,
o A list of addresses to act as a proxy gateway, and
o A set of configurable parameters, e.g., timers, to tune the
performance of the routing protocol.
Once in operation, the DYMO routers will maintain a set of state
information, which is temporal in nature. E.g., to prevent the
creation of routing loops, DYMO routers maintain, increment and
append sequence numbers to Routing Messages (RMs). The current
router sequence number is an example of local state information.
Further, as the router discovers and overhears path information to
various TNs in the MANET, the DYMO router populates this knowledge in
it's local Routing Information Base (RIP). Entries in the RIB tell
the local routing the next hop and interface to forward data packets
destine for a given TN. The DYMO routers are responsible for
tracking the availability of the next hop links which are registered
in their RIB. Hence, DYMO routers dynamically maintain a set of
state objects, including:
o
Routing in a MANET is a tricky endeavor. The DYMO routing process
Cole & Chakeres Expires August 21, 2008 [Page 4]
Internet-Draft The DYMO MIB February 2008
contains numerous configurable parameters which impact the overall
performance of the MANET. Hence, the DYMO MIB defines a set of
Performance and Notification objects to aid network administrators to
track the overall health of the routing process and to aid in fault
isolation and correction of routing related problems.
4.1. Terms
The following definitions apply throughout this document:
o Configuration Objects - switches, tables, objects which are
initialized to default settings or set through the management
interface defined by this MIB.
o Tunable Configuration Objects - objects whose values affect timing
or attempt bounds on the DYMO protocol.
o State Objects - automatically generated values which define the
current operating state of the DYMO protocol process in the
router.
o Performance Objects - automatically generated values which help an
administrator or automated tool to assess the performance of the
DYMO protocol process on the router and the overall routing
performance within the DYMO routing domain.
4.2. Organization
This document is organized as ...
5. Structure of the MIB Module
This section presents the structure of the DYMO MIB module. The
objects are arranged into the following groups:
o General Information Group - ...
o Configuration Group - ...

5.1. Textual Conventions
This section is TBD.
5.2. The General Information Group
This section provides general information about the capabilities of
the routing device. ...
5.3. The Configuration Group
The device is configured with a set of controls. These will serve as
the object descriptions once they are discussed and refined. A
potential list of configuration controls for the DYMO-MIB, include:
Protocol Configuration Parameters:
o RREP_GENERATION, 0=all unknown, 1=following list
o IS_GATEWAY, 0=no, 1=yes
o RESPONSIBLE_ADDRESSES, Self or Prefix, 0=self, 1=user specified
o DYMO_INTERFACES, User Specified, 0=all, 1=user specified
o INCLUDE_TARGET_INFORMATION, Yes - TargetNode.AddTLV.SeqNum,
TargetNode.AddTLV.Dist, TargetNode.AddTLV.Prefix
o APPEND_OWN_ADDRESSES, Yes for RREQ
o INCREMENT_OWN_SEQNUM_ON_APPEND, Yes for RREQ

AdditionalNode.AddTLV.SeqNum, AdditionalNode.AddTLV.Dist,
AdditionalNode.AddTLV.Prefix
o GENERATE_RERR_IMMEDIATELY, No
o RERR_INCLUDE_ALL_UNREACHABLES, Yes
o UNKNOWN_TYPE_HANDLING, Ignore
Cole & Chakeres Expires August 21, 2008 [Page 6]
Internet-Draft The DYMO MIB February 2008
Protocol Tuning Configuration Parameters:
o MAX_HOPLIMIT - 10 hops ([I-D:ietf-manet-dymo], sect. 5.3.1)
o BUFFER_SIZE_PACKETS, 50 packets
o BUFFER_SIZE, 1500 * BUFFER_SIZE_PACKETS
o PACKET_RATE_THROTTLE - ([I-D:ietf-manet-dymo], sect. 5.9)
Timer Configuration - ([I-D:ietf-manet-dymo], sect. 5.2.3):
o ROUTE_TIMEOUT - 5 seconds ([I-D:ietf-manet-dymo], sect. 6)
o NET_TRANSVERSAL_TIME - 1000 msec ([I-D:ietf-manet-dymo], sect. 6)
o ROUTE_DELETE_TIMEOUT - 2*ROUTE_TIMEOUT
o ROUTE_AGE_MAX_TIMEOUT - 60 sec
o ROUTE_AGE_MIN_TIMEOUT - NET_TRAVERSAL_TIME
o ROUTE_NEW_TIMEOUT - ROUTE_TIMEOUT
o ROUTE_USED_TIMEOUT - ROUTE_TIMEOUT
o RREQ_WAIT_TIME - 2*NET_TRAVERSAL_TIME ([I-D:ietf-manet-dymo],
sect. 5.4)
o RREQ_TRIES - 3 retries ([I-D:ietf-manet-dymo], sect. 5.4)
o UNICAST_MESSAGE_SENT_TIMEOUT - 1 sec ([I-D:ietf-manet-dymo], sect.
6)
Configuration Tables:
o LocalHosts - If RESPONSIBLE_ADDRESSES is set to other than self
address, then the DYMO router must be configured with the set of
local host addresses for which it is to generate RREP messages.
o TargetAddresses - If RREP_GENERATION is set to other than all,
then the DYMO router must be configured with a set of addresses
for which it is to generate RREQ messages.
o DymoInterfaces - If DYMO_INTERFACES is set to other than all, then
the DYMO router must be told which interfaces to run the DYMO
protocol over. ([I-D:ietf-manet-dymo], sect. 5.9). This would be
a table containing the interfaces and associated information.
Cole & Chakeres Expires August 21, 2008 [Page 7]
Internet-Draft The DYMO MIB February 2008
o GatewayResponsibleAddresses - If IS_GATEWAY is set, then the DYMO
router requires Dymo-gateway configuration parameters, e.g.,
addresses to proxy RM ([I-D:ietf-manet-dymo], sect. 5.8). This
would be a table containing the addresses and associated
information.
5.4. The State Group
The State Subtree reports current state information, including
forwarding tables. State information falls into 'General', 'Routing
Information Base (RIB)', and 'Current Neighbors Table'. These are
separately discussed below.
(Note: these will serve as the object descriptions once they are
discussed and refined.)
5.4.1. General State Information
General state information could include:
o DYMO Version Number -
o Current Sequence Number - ([I-D:ietf-manet-dymo], sect. 3)
5.4.2. Routing Information Base
The Routing Information Base (RIB) - ([I-D:ietf-manet-dymo], sect.
4.1), includes table entries with the following mandatory objects,
i.e.,
o Route.Address
o Route.SeqNum
o Route.NextHopAddress
o Route.NextHopInterface
o Route.Broken
and the following optional objects, i.e.,
o Route.Distance
o Route.Prefix
One consideration is how to handle RREQ which are in progress. The
DYMO-MIB may want to populate a row in the RIB with the target
Cole & Chakeres Expires August 21, 2008 [Page 8]
Internet-Draft The DYMO MIB February 2008
address and have an indication that a RREQ is pending. Another
option is to have a separate table containing pending information.
5.4.3. Current NextHop Table
The current nexthop table - ([I-D:ietf-manet-dymo], sect. 5.5.1),
includes a table of active (i.e., currently found as Next Hop
addresses in the router's RIB) links to neighbors. This table could
be populated by various means, including the use of the NHDP [I-D:
ietf-manet-nhdp].
5.5. The Performance Group
Reports values relevant to system performance. These will serve as
the object descriptions once they are discussed and refined.)
Not sure this is something that would be useful to network managers.
But it may be useful to have a set of performance related counters
available through the DYMO-MIB. These could also be potentially
useful in conjunction with traps or informs.
One set of potential performance counters can be derived from the
various configuration limits and timeout values. These performance
counters would register the number of faults related to these
configurable parameters. These would potentially aid in parameter
tuning and routing protocol optimization.
Another specific example would be the number of data packets awaiting
a route, or a counter indicating the number of buffer overflows, etc.
Another set, is the initial set of performance parameters written
into this version of the DYMO-MIB draft are counters related to the
number of RMs, RREQs, RREPs, and RERR messages. We could expose only
aggregate information in the form of counters as shown below. Or
could build tables indexed by InetAddress of targets.
5.6. The Notifications Group
The Notifications Subtree contains the list of notifications
supported within the DYMO-MIB and their intended purpose or utility.
What would be a potential list of notifications for the DYMO-MIB,
e.g.,
o

6. Relationship to Other MIB Modules
[TODO]: The text of this section specifies the relationship of the
MIB modules contained in this document to other standards,
particularly to standards containing other MIB modules. Definitions
imported from other MIB modules and other 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 [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 DYMO-MIB does not
duplicate those objects.
6.2. Relationship to the IF-MIB
[TODO] This section is included as an example; If the MIB module is
not an adjunct of the Interface MIB, then this section should be
removed.
6.3. MIB modules required for IMPORTS
[TODO]: Citations are not permitted within a MIB module, but any
module mentioned in an IMPORTS clause or document mentioned in a
REFERENCE clause is a Normative reference, and must be cited
someplace within the narrative sections. If there are imported items
in the MIB module, such as Textual Conventions, that are not already
cited, they can be cited in text here. Since relationships to other
MIB modules should be described in the narrative text, this section
is typically used to cite modules from which Textual Conventions are
imported.
The following DYMO-MIB module IMPORTS objects from SNMPv2-SMI
[RFC2578], SNMPv2-TC [RFC2579], SNMPv2-CONF [RFC2580], and IF-MIB
[RFC2863]

8. Security Considerations
[TODO] Each specification that defines one or more MIB modules MUST
contain a section that discusses security considerations relevant to
those modules. This section MUST be patterned after the latest
approved template (available at
http://www.ops.ietf.org/mib-security.html). Remember that the
objective is not to blindly copy text from the template, but rather
to think and evaluate the risks/vulnerabilities and then state/
document the result of this evaluation.
[TODO] if you have any read-write and/or read-create objects, please
include the following boilerplate paragraph.
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 [TODO] writeable MIB objects that could be especially disruptive
if abused MUST be explicitly listed by name and the associated
security risks MUST be spelled out; RFC 2669 has a very good
example.
o [TODO] list the writable tables and objects and state why they are
sensitive.
[TODO] else if there are no read-write objects in your MIB module,
use the following boilerplate paragraph.
There are no management objects defined in this MIB module that have
a MAX-ACCESS clause of read-write and/or read-create. So, if this
MIB module is implemented correctly, then there is no risk that an
intruder can alter or create any management objects of this MIB
module via direct SNMP SET operations.
[TODO] if you have any sensitive readable objects, please include the
following boilerplate paragraph.
Cole & Chakeres Expires August 21, 2008 [Page 27]
Internet-Draft The DYMO MIB February 2008
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:
o [TODO] you must explicitly list by name any readable objects that
are sensitive or vulnerable and the associated security risks MUST
be spelled out (for instance, if they might reveal customer
information or violate personal privacy laws such as those of the
European Union if exposed to unathorized parties)
o [TODO] list the tables and objects and state why they are
sensitive.
[TODO] discuss what security the protocol used to carry the
information should have. The following three boilerplate paragraphs
should not be changed without very good reason. Changes will almost
certainly require justification during IESG review.
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 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.
9. IANA Considerations
[TODO] In order to comply with IESG policy as set forth in
http://www.ietf.org/ID-Checklist.html, every Internet-Draft that is
submitted to the IESG for publication MUST contain an IANA
Considerations section. The requirements for this section vary
depending what actions are required of the IANA. see RFC4181 section
Cole & Chakeres Expires August 21, 2008 [Page 28]
Internet-Draft The DYMO MIB February 2008
3.5 for more information on writing an IANA clause for a MIB module
document.
[TODO] select an option and provide the necessary details.
Option #1:
The MIB module in this document uses the following IANA-assigned
OBJECT IDENTIFIER values recorded in the SMI Numbers registry:
Descriptor OBJECT IDENTIFIER value
---------- -----------------------
sampleMIB { mib-2 XXX }
Option #2:
Editor's Note (to be removed prior to publication): the IANA is
requested to assign a value for "XXX" under the 'mib-2' subtree and
to record the assignment in the SMI Numbers registry. When the
assignment has been made, the RFC Editor is asked to replace "XXX"
(here and in the MIB module) with the assigned value and to remove
this note.
Note well: prior to official assignment by the IANA, a draft document
MUST use placeholders (such as "XXX" above) rather than actual
numbers. See RFC4181 Section 4.5 for an example of how this is done
in a draft MIB module.
Option #3:
This memo includes no request to IANA.
10. Contributors
This MIB document uses the template authored by D. Harrington which
is based on contributions from the MIb Doctors, especially Juergen
Schoenwaelder, Dave Perkins, C.M.Heard and Randy Presuhn.

Appendix A. Change Log
The following changes have been made from draft-cole-dymo-mib-00 .
Not applicable to draft 00
1.
Appendix B. Open Issues
This section contains the set of open issues related to the
development and design of the DYMO-MIB. This section will not be
present in the final version of the MIB and will be removed once all
the open issues have been resolved.
1. Agree on set of configuration options to be supported, e.g.,
Gateway config, local hosts, responsible addresses, etc.
2. Will DYMO require an InstanceID for running multiple, concurrent
DYMO domains within a single router?
3. Is support for addresses-less interfaces required?
Cole & Chakeres Expires August 21, 2008 [Page 30]
Internet-Draft The DYMO MIB February 2008
4. Incorporate MIB-II IfGroup interworking with DymoIfTable.
5. Incorporate MIB-II IpGroup interworking with DymoIfTable.
6. Incorporate MIB-II IpForwardingGroup interworking with
DymoRIBTable.
7. What performance objects are of interest and utility?
8. What notifications are of interest and utility?
9. Work on the Security Section. This MIB does have settable
objects, but not sensitive objects (true?).
10. Work on the relationship to other MIBs, IF-MIB, NHDP-MIB.
11. Identify all objects requiring non-volatile storage in their
DESCRIPTION clauses.
12. Incorporate parameter relationship conditions into their
DESCRIPTION clauses.
13. Work up a better management model in the textual description of
the DYMO-MIB. Perhaps include management usecases.
14. Cleanup all the [TODOs] from the MIB template.
