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.

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

4. Acknowledgments
This document is a product of the IETF's Internetworking Over NBMA
Networks (ion) Working Group.
The authors would like to thank Avri Doria (Bytex) for his efforts on
the first draft of the NHRP MIB and Keith McCloghrie (cisco) and
David Horton (CITR) for their feedback and suggestions. Also, we
would like to thank Naganand Doraswamy (Bay Networks) for his
assistance with the "Security Considerations" section.

6. 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.
