Expires May 1999 [Page 1] INTERNET-DRAFT NHRP MIB November 1998 Abstract This memo defines an experimental portion of the Management Information Base (MIB) for use with network management protocols in the Internet community. In particular, it describes managed objects for the Next Hop Resolution Protocol (NHRP) as defined in RFC 2332. 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. This memo does not specify a standard for the Internet community. 1. The SNMP Management Framework The SNMP Management Framework presently consists of five major components: o An overall architecture, described in RFC 2271 [1]. o Mechanisms for describing and naming objects and events for the purpose of management. The first version of this Structure of Management Information (SMI) is called SMIv1 and described in RFC 1155 [2], RFC 1212 [3] and RFC 1215 [4]. The second version, called SMIv2, is described in RFC 1902 [5], RFC 1903 [6] and RFC 1904 [7]. o Message protocols for transferring management information. The first version of the SNMP message protocol is called SNMPv1 and described in RFC 1157 [8]. A second version of the SNMP message protocol, which is not an Internet standards track protocol, is called SNMPv2c and described in RFC 1901 [9] and RFC 1906 [10]. The third version of the message protocol is called SNMPv3 and described in RFC 1906 [10], RFC 2272 [11] and RFC 2274 [12]. o Protocol operations for accessing management information. The first set of protocol operations and associated PDU formats is described in RFC 1157 [8]. A second set of protocol operations and associated PDU formats is described in RFC 1905 [13]. o A set of fundamental applications described in RFC 2273 [14] and the view-based access control mechanism described in RFC 2275 [15]. Managed objects are accessed via a virtual information store, termed the Expires May 1999 [Page 2] INTERNET-DRAFT NHRP MIB November 1998 Management Information Base or MIB. Objects in the MIB are defined using the mechanisms defined in the SMI. This memo specifies a MIB module that is compliant to the SMIv2. A MIB conforming to the SMIv1 can be produced through the appropriate translations. The resulting translated MIB must be semantically equivalent, except where objects or events are omitted because no translation is possible (use of Counter64). Some machine readable information in SMIv2 will be converted into textual descriptions in SMIv1 during the translation process. However, this loss of machine readable information is not considered to change the semantics of the MIB. Expires May 1999 [Page 3] INTERNET-DRAFT NHRP MIB November 1998 2. Structure of the MIB The NHRP MIB contains three groups: the General Group, the Client Group, and the Server Group. 2.1. The NHRP General Group The General Group contains objects that apply to both clients and servers -- in particular the nhrpNextIndex scalar object, the NHRP Next Hop Resolution Cache Table and the NHRP Purge Request Table. The nhrpNextIndex scalar object is used to provide unique indices for the nhprClientIndex in the nhrpClientTable and the nhrpServerIndex in the nhrpServerTable. If used, this object should reduce or eliminate multiple managers creating rows simultaneously in the same table. 2.1.1. The NHRP Next Hop Resolution Cache Table The NHRP Next Hop Resolution Cache Table represents the internetwork layer address to NBMA address cache that is maintained by both NHRP clients and NHRP servers. The NHRP Next Hop Resolution Cache Table contains an ifIndex as part of the Index Clause. This ifIndex represents the use of a generic ifIndex, such that the value of this ifIndex SHOULD reflect a specific NBMA subnetwork related interface as determined by an implementation. For example, assuming that the NBMA subnetwork is ATM, then it is up to the implementors of this MIB to determine their own ATM interface layering (assuming compliance with the IF-MIB (either RFC 1573 or RFC 2233) and the ATM-MIB (RFC 1695)). In other words, still assuming that the NBMA subnetwork is ATM, the ifIndex in the NHRP Cache Table would represent the ifIndex containing or consisting of the VC (or shortcut) denoted by this Table entry. 2.1.2. The NHRP Purge Request Table The NHRP Purge Request Table is a way to track Purge Request Information. 2.2. The NHRP Client Group The Client Group contains objects that only apply to NHRP clients (NHCs). 2.2.1. The NHRP Client Table The NHRP Client Table contains entries for NHRP Next Hop Clients (NHCs) associated with this agent. Each row in the table represents a single NHC. The RequestID used in Registration requests needs to be saved to Expires May 1999 [Page 4] INTERNET-DRAFT NHRP MIB November 1998 non-volatile storage. Depending upon the implementation, this may or may not impact how the StorageType is used. For a complete description of how the Registration RequestID is used, see Section 5.2.3 of [16]. 2.2.2. The NHRP Client Registration Table The NHRP Client Registration Table contains information on registration requests which need to be maintained by the Clients. Each entry in this table represents a single registration request. Note: since the NHRP specification does not mandate a refresh algorithm, this table omits refresh information, however, this table does contain information for all the registration requests which need to be maintained by the NHRP Clients. 2.2.3. The NHRP Client NHS Table The NHRP Client NHS Table contains the NBMA subnetwork addresses of servers configured for use by the client. By default, the agent will add an entry to this table which corresponds to the client's default router. 2.2.4. The NHRP Client Statistics Table The NHRP Client Statistics Table contains NHRP statistics maintained by a client. These statistics include counters on requests and replies, as well as counters for errors which are encountered by the Clients. 2.3. The NHRP Server Group The Server Group contains objects that only apply to NHRP servers (NHSes). 2.3.1. The NHRP Server Table The NHRP Server Table contains entries for each server associated with this agent. 2.3.2. The NHRP Server Next Hop Resolution Cache Table The NHRP Server Next Hop Resolution Cache Table contains additional objects that a server keeps for each entry in its cache. This table extends the NHRP Next Hop Resolution Cache Table defined in the General Group. Expires May 1999 [Page 5] INTERNET-DRAFT NHRP MIB November 1998 2.3.3. The NHRP Server NHC Table This table contains information about all the Clients known to the Servers. 2.3.4. The NHRP Server Statistics Table The NHRP Server Statistics Table contains NHRP statistics maintained by a server. These statistics include counters on requests and replies, as well as counters for errors which are encountered by the Servers. 3.

IANA Considerations The Internet Assigned Numbers Authority (IANA) has been and continues to be responsible for maintaining the ADDRESS FAMILY NUMBERS (http://www.isi.edu/in-notes/iana/assignments/address-family- numbers) name space assignments. The request made here is for the IANA to place this list in a MIB module, such that it may be imported into other MIBs. The motivation for doing this is to allow MIBs to not have to change when a new assignment is made to the ADDRESS FAMILY NUMBERS. This is very similar to the motivation behind the IANAifType-MIB. An example of what the MIB would look like is included in this document. Please be aware that the MIB enumerates the ADDRESS FAMILY NUMBERS values starting with 0 (zero). This was done to preserve the current values given to the ADDRESS FAMILY VALUES, however, at some point in the SNMP community enumerations began with 1 (one) and not 0 (zero). Any additions or changes to the list of ADDRESS FAMILY NUMBERS registered via IANA will be done as they have in the past and this document does not propose any changes to the ADDRESS FAMILY NUMBERS other than to place them into a MIB, of which an example is given in this document (see IANA Address Family Numbers MIB).

Security Considerations Managed Objects which would configure/expose the security portion of the NHRP protocol [1] could result in the NHRP protocol being unsecure and vulnerable. In other words, since there is very minimal security provided with SNMPv1, and SNMPv3 is at proposed Standard and is not in wide-spread usage, this MIB document does not contain objects which would jeopardize the security of NHRP. Having such objects configurable/visable through SNMP would defeat the purpose of NHRP's security mechanisms. The following items/objects may be considered when implementing the security aspects of NHRP. Items denoted as (configurable) are those which would need values. Items denoted as (read- only) are those which may provide relevant information or may be useful in debugging. 1. (configurable) enable/disable security 2. (configurable) SPI (security parameter index). Depending upon the implementation, there may be multiple SPIs, and these would be configurable also. For example, if the implementation switched to a different SPI after a given time. 3. (configurable) algorithm. The HMAC-MD5-128 is the default hash algorithm. 4. (configurable) lifetime value in seconds. 5. (read-only) key. 6. (read-only) list of users who have access to the above information.

IANA Address Family Numbers MIB This appendix defines the initial content of the IANAaddressFamilyNumbers-MIB. This section should be removed from this document prior to its approval, at which time this MIB will be administered by IANA. The enumeration values start at 0 (zero) and not 1 (one) as with most enumerations. The branch for this MIB needs to be Expires May 1999 [Page 70] INTERNET-DRAFT NHRP MIB November 1998 determined, and an appropriate number should be added where XXX is currently.
