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 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:
- The tripConfigGroup contains the common configuration objects applicable to all TRIP applications referenced by the applIndex.
- The tripPeerTableConfigGroup contains the configuration objects applicable to all TRIP peers of the Location Server referenced by the applIndex.
- The tripRouteGroup contains the configuration objects related to the routes of all TRIBs of this Location Server.
- The tripItadTopologyGroup contains information about the topology of the TRIP ITADs concerning this Location Server.
- The tripPeerTableStatsGroup contains the statistical objects applicable to all TRIP peers of the Location Server referenced by the applIndex.
- The tripNotificationGroup contains notifications that the TRIP application can generate.
- 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:
-
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.
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.
