2. Abstract
This document describes a management information base for the IS-IS
Routing protocol, as described in ISO 10589 [2], when it is used to
construct routing tables for IP networks, as described in RFC 1195
[RFC1195].
This memo defines an experimental portion of the Management
Information Base (MIB) for use with network management protocols in
the Internet community.
This memo is based on an IETF draft by Chris Gunner [1]. This
version has been modified to include MIB-II syntax, to exclude
portions of the protocol that are not relevant to IP, such as the
ES-IS protocol, and to add management support for current practice.

4. Overview
This document is provided to the IETF working group on IS-IS.
The IS-IS MIB includes of the following objects
System-wide Attributes
- isisSystem
This table contains information specific to a single instance of
the IS-IS protocol running on a router.
- isisManAreaAddr
Jeff Parker - Expires May 2003 [Page 2]
Internet Draft - draft-ietf-isis-wg-mib-11.txt Feb 2003
This table includes area addresses manually configured which are
used to control the associations formed between Level 1
Intermediate Systems.
- isisAreaAddr
This table includes area addresses reported in relevant L1 LSPs.
- isisSysProtSupp
This table includes the manually configured list of protocols,
such as IP or CLNS, supported by the Intermediate System.
- isisSummAddr
This table holds summary addresses configured for each Level 2
instance of the IS-IS protocol running on a router.
- isisRedistributeAddr
This table provides criteria to decide if a route should be
leaked from L2 to L1 when Domain Wide Prefix leaking is enabled.
- isisRouter
This table holds the hostname and router ID for an Intermediate
System.
- isisSysLevel
This table contains information specific to a domain(Level-2) or
an area(Level-1) of the IS-IS protocol.
Circuit-specific Attributes
- isisCirc
This table contains information specific to a broadcast or
point-to-point interface in the system.
- isisCircLevel
This table contains information specific to a one Level 1 or
Level 2 of an interface.
Jeff Parker - Expires May 2003 [Page 3]
Internet Draft - draft-ietf-isis-wg-mib-11.txt Feb 2003
Counters
- isisSystemCounter
Counters in the System table, such as times we have wraped a
sequence counter on one of our Link State PDUs.
- isisCircuitCounter
Counters of events particular to a circuit, such as PDUs with an
illegal value of the System ID field length.
- isisPacketCounter
Counts of ISIS Protocol PDUs broken down into packet type.
Attributes associated with an Adjacency
- isisISAdj
This table contains information about adjacencies to routers
maintained by the protocol. Entries in this table cannot be
created by management action: they are established through the
Hello protocol.
- isisISAdjAreaAddr
This table contains the set of Area Addresses of neighboring
Intermediate Systems as reported in IIH PDUs.
- isisISAdjIPAddr
This table contains the set of IP Addresses of neighboring
Intermediate Systems as reported in received IIH PDUs.
- isisISAdjProtSupp
This table contains the set of protocols supported by neighboring
Intermediate Systems as reported in received IIH PDUs.
Attributes associated with configured addresses
- isisRA
Jeff Parker - Expires May 2003 [Page 4]
Internet Draft - draft-ietf-isis-wg-mib-11.txt Feb 2003
The Reachable Address Table.
This table contains information about an address prefix manually
configured on the system or learned through another protocol.
- isisIPRA
The IP Reachable Address Table.
This table contains information about IP reachable address
manually configured on this system or learned from another
protocol.
Attributes associated with Link State PDU Table
- isisLSP
The Link State PDU Summary Table
This table contains information contained in the headers of Link
State PDUs stored by the system.
The Link State PDU TLV Table
This table holds the sequence of TLVs that make up an LSP
fragment.
Attributes associated with a Notification
- isisNotification
This table defines attributes that will be included when
reporting IS-IS notifications.
The SNMP Management Framework presently consists of five major
components:
An overall architecture, described in RFC 2571 [RFC2571].
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 STD 16,
Jeff Parker - Expires May 2003 [Page 5]
Internet Draft - draft-ietf-isis-wg-mib-11.txt Feb 2003
RFC 1155 [RFC1155], STD 16, RFC 1212 [RFC1212] and RFC 1215
[RFC1215]. The second version, called SMIv2, is described in STD 58,
RFC 2578 [RFC2578], STD 58, RFC 2579 [RFC2579] and STD 58, RFC 2580
[RFC2580].
Message protocols for transferring management information. The first
version of the SNMP message protocol is called SNMPv1 and described
in STD 15, RFC 1157 [RFC1157]. A second version of the SNMP message
protocol, which is not an Internet standards track protocol, is
called SNMPv2c and described in RFC 1901 [RFC1901] and RFC 1906
[RFC1906]. The third version of the message protocol is called
SNMPv3 and described in RFC 1906 [RFC1906], RFC 2572 [RFC2572] and
RFC 2574 [RFC2574].
Protocol operations for accessing management information. The first
set of protocol operations and associated PDU formats is described in
STD 15, RFC 1157 [RFC1157]. A second set of protocol operations and
associated PDU formats is described in RFC 1905 [RFC1905].
A set of fundamental applications described in RFC 2573 [RFC2573] and
the view-based access control mechanism described in RFC 2575
[RFC2575].
A more detailed introduction to the current SNMP Management Framework
can be found in RFC 2570 [RFC2570].
Managed objects are accessed via a virtual information store, termed
the 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.

DESCRIPTION
"The type of mapping to be employed to ascertain the SNPA
Address which should be used in forwarding PDUs for this
Reachable Address prefix. This object follows the
ManualOrAutomatic behavior. The following values of
mapping type are defined:
none: The mapping is null because the neighbor SNPA is
implicit by nature of the subnetwork (e.g. a

point-to-point linkage).
explicit: The subnetwork addresses in the object
isisRASNPAAddress is to be used.
extractIDI: The SNPA is embedded in the IDI of
the destination NSAP Address. The mapping
algorithm extracts the SNPA to be used
according to the format and encoding rules of
ISO8473/Add2. This SNPA extraction algorithm can
be used in conjunction with Reachable Address
prefixes from the X.121, F.69, E.163 and E.164
addressing subdomains.
extractDSP: All, or a suffix, of the SNPA is embedded
in the DSP of the destination address. This SNPA
extraction algorithm extracts the embedded
subnetwork addressing information by performing a
logical AND of the isisRASNPAMask object value with
the destination address. The part of the SNPA
extracted from the destination NSAP is appended to
the isisRASNPAPrefix object value to form the next
hop subnetwork addressing information."

DESCRIPTION
"A bit mask with 1 bits indicating the positions in the
effective destination address from which embedded SNPA
information is to be extracted. For the extraction the
first octet of the isisRASNPAMask object value is aligned
with the first octet (AFI) of the NSAP Address. If the
isisRASNPAMask object value and NSAP Address are of
different lengths, the shorter of the two is logically
padded with zeros before performing the extraction. This
object follows the ManualOrAutomatic behavior."

entire SNPA is embedded in the DSP the SNPA Prefix shall
be null. This object follows the ManualOrAutomatic
