Expires July 1998 [Page 1] INTERNET-DRAFT NHRP MIB January 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 [1]. This memo specifies a MIB module in a manner that is both compliant to the SNMPv2 SMI, and semantically identical to the peer SNMPv1 definitions. This memo does not specify a standard for the Internet community. 1. The SNMP Network Management Framework The SNMP Network Management Framework presently consists of three major components. They are: o the SMI, described in RFC 1902 [2] - the mechanisms used for describing and naming objects for the purpose of management. o the MIB-II, STD 17, RFC 1213 [3] - the core set of managed objects for the Internet suite of protocols. o the protocol, RFC 1157 [4] and/or RFC 1905 [5], - the protocol for accessing managed objects. The Framework permits new objects to be defined for the purpose of experimentation and evaluation. 1.1. Object Definitions Managed objects are accessed via a virtual information store, termed the Management Information Base or MIB. Objects in the MIB are defined using the subset of Abstract Syntax Notation One (ASN.1) defined in the SMI. In particular, each object type is named by an OBJECT IDENTIFIER, an administratively assigned name. The object type together with an object instance serves to uniquely identify a specific instantiation of the object. For human convenience, we often use a textual string, termed the descriptor, to also refer to the object type. Expires July 1998 [Page 2] INTERNET-DRAFT NHRP MIB January 1998 2. Overview 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 NHRP Next Hop Resolution Cache Table. This table represents the internetwork layer address to NBMA address cache that is maintained by both NHRP clients and NHRP servers. 2.2. The NHRP Client Group The Client Group contains objects that only apply to NHRP clients (NHCs). The NHRP Client Table contains entries for each client associated with this agent. Some agents will allow entries to be created and deleted from this table which starts and stops the client entity on the station. The NHRP Client NHS Table contains the NBMA subnetwork addresses of servers configured for use by the client. The NHRP Client Statistics Table contains NHRP statistics maintained by a client. 2.3. The NHRP Server Group The Server Group contains objects that only apply to NHRP servers (NHSes). The NHRP Server Table contains entries for each server associated with this agent. Some agents will allow entries to be created and deleted from this table which starts and stops the server entity on the station. 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. The NHRP Server Statistics Table contains NHRP statistics maintained Expires July 1998 [Page 3] INTERNET-DRAFT NHRP MIB January 1998 by a server. 3.

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 vunerable. 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. 7. Authors' Addresses James V.
