Internet-Draft RPL MIB March 2012
1. Introduction
This memo defines a portion of the Management Information Base (MIB)
for use with network management protocols. In particular it defines
objects for managing the IPv6 Routing Protocol for Low Power and
Lossy Networks (RPL) [I-D.ietf-roll-rpl]. It also provides
management access to the Trickle [RFC6206] parameters as they are
used by RPL.
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 MIB module is organized into a group of scalars and tables.

5. Relationship to Other MIB Modules
The MIB module IMPORTS definitions from SNMPv2-SMI [RFC2578],
SNMPv2-TC [RFC2579], SNMPv2-CONF [RFC2580], IF-MIB [RFC2863] and the
INET-ADDRESS-MIB [RFC4001].
The IPv6 routing table should be exposed via the inetCidrRouteTable
defined in the IP-FORWARD-MIB [RFC4292]. XXX: We need to clarify
whether the inetCidrRoutePolicy can / should point to the DODAG
instance.

7. Security Considerations
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 rplActiveInstance: [ TBD ] explain sensitivity
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:
Korte, et al. Expires September 13, 2012 [Page 26]
Internet-Draft RPL MIB March 2012
[TODO: Need to describe vulnerabilities here.]
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.
8. IANA Considerations
IANA is requested to assign a value for "XXXX" 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
"XXXX" (here and in the MIB module) with the assigned value and to
remove this note.
IANA has allocated a number for RPL in the IANAipRouteProtocol
textual convention of the IANA-RTPROTO-MIB.
