RFC 3872 MIB for TRIP September 2004
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 module objects are
generally accessed through the Simple Network Management Protocol
(SNMP). Objects in this MIB module 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. 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 a set of managed objects that are used
to schedule management operations periodically or at specified dates
and times. Since TRIP [RFC3219] is modeled after the Border Gateway
Protocol (BGP-4) [RFC1771], the managed objects for TRIP are also
modeled after RFC1657 - Definitions of Managed Objects for the
Fourth Version of the Border Gateway Protocol (BGP-4) using SMIv2
[RFC1657].
3. Conventions used in this document
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 BCP 14, RFC 2119
[RFC2119].
4. Overview
This MIB module provides managed objects for TRIP devices defined in
Telephony Routing over IP [RFC3219]. TRIP is an inter-domain
application-layer control protocol that exchanges information
between TRIP location servers (LS) to provide efficient IP telephony
routing.
5. Structure of TRIP MIB
This MIB module utilizes the framework described in RFC 2788
[RFC2788] for management of multiple instances of TRIP from a single
entity. The Network Services Monitoring MIB module applTable will
be populated with entries corresponding to each TRIP Location Server
Zinman, et al. Standards Track [Page 2]
RFC 3872 MIB for TRIP September 2004
in the system. Each TRIP Location Server will then have an
applIndex associated with it. The value assigned to applIndex will
represent the distinct instance of TRIP.
The TRIP MIB module contains the following groups of objects with
each group as part of the management of a singular TRIP entity. Each
group covers a section of functionality of TRIP:
o The tripConfigGroup contains the common configuration objects
applicable to all TRIP applications referenced by the applIndex.
o The tripPeerTableConfigGroup contains the configuration objects
applicable to all TRIP peers of the Location Server referenced by
the applIndex.
o The tripRouteGroup contains the configuration objects related to
the routes of all TRIBs of this Location Server.
o The tripItadTopologyGroup contains information about the topology
of the TRIP ITADs concerning this Location Server.
o The tripPeerTableStatsGroup contains the statistical objects
applicable to all TRIP peers of the Location Server referenced by
the applIndex.
o The tripNotificationGroup contains notifications that the TRIP
application can generate.
o The tripNotifObjectGroup contains the objects needed by one or
more of the notifications.
5.1. Textual Conventions
The data types TripItad and TripId are used as textual conventions
in this document. A TRIP ITAD (IP Telephony Administrative Domain)
is described in [RFC3219]. A TRIP ID is used as a distinct
identifier for a TRIP Location Server. A TripAppProtocol is used to
identify an application protocol. A TripAddressFamily is used to
define an address family. TripCommunityId is used as a distinct
identifier for a TRIP community. TripProtocolVersion depicts the
version number of the TRIP protocol. TripSendReceiveMode describes
the operational mode of the TRIP application.

7. Security Considerations
The managed objects in this MIB module contain sensitive information
since, collectively, they allow tracing and influencing of
connections in TRIP devices and provide information of their
connection characteristics. As such, improper manipulation of the
objects represented by this MIB module MAY result in denial of
service to a large number of available routes.
There are a number of management objects defined in this MIB module
that have 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 objects include:
Zinman, et al. Standards Track [Page 48]
RFC 3872 MIB for TRIP September 2004
tripCfgItad:
Improper setting of tripCfgItad value can make all peer
connections drop and not be re-established.
tripCfgAdminStatus:
Improper setting of tripCfgAdminStatus from up to down will cause
the TRIP Location Server stop processing TRIP messages.
tripCfgPort:
Improper setting of tripCfgPort can cause the failure of a peer
establishing a connection.
tripCfgMinItadOriginationInterval,
tripCfgMinRouteAdvertisementInterval:
Improper configuration of these values MAY adversely affect local
and global convergence of the routes advertised by this TRIP
Location Server.
tripPeerAdminStatus:
Improper setting of tripPeerAdminStatus from up to down can cause
significant disruption of the connectivity to the destination via
the applicable remote TRIP Location Server peer.
tripPeerConnectRetryInterval,tripPeerMaxRetryInterval:
Improper configuration of these values can cause connections to be
disrupted for extremely long time periods when otherwise they
would be restored in a relatively short period of time.
tripPeerHoldTimeConfigured, tripPeerKeepAliveConfigured:
Improper configuration of these value can make TRIP peer sessions
more fragile and less resilient to denial of service attacks.
There are a number of managed objects in this MIB module that contain
sensitive information regarding the operation of a network. For
example, a TRIP Location Server peer's local and remote addresses
might be sensitive for ISPs who want to keep interface addresses on
TRIP Location Server confidential so as to prevent TRIP Location
Server addresses used for a denial of service attack or address
spoofing.
Therefore, it is thus important to control even GET access to these
objects and possibly to even encrypt the values of these object when
sending them over the network via SNMP. Not all versions of SNMP
provide features for such a secure environment.
Zinman, et al. Standards Track [Page 49]
RFC 3872 MIB for TRIP September 2004
SNMPv1 by itself is not a secure environment. 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 the 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.
