Abstract

This memo defines an update to RFC 1354, "IP Forwarding Table MIB", for Classless Inter-Domain Routing (CIDR). That document was developed by the Router Requirements Working Group as an update to RFC 1213's ipRouteTable, with the display of multiple routes as a primary objective. The significant difference between this MIB and RFC 1354 is the recognition (explicitly discussed but by consensus left to future work) that CIDR routes may have the same network number but different network masks. Note that this MIB obsoletes a number of objects from RFC 1354. The reader should pay careful attention to the STATUS field.

1. Introduction

This memo defines an update to RFC 1354, "IP Forwarding Table MIB",

for Classless Inter-Domain Routing (CIDR). That document was

developed by the Router Requirements Working Group as an update to

RFC 1213's ipRouteTable, with the display of multiple routes as

a primary objective. The significant difference between this MIB and

RFC 1354 is the recognition (explicitly discussed but by consensus

left to future work) that CIDR routes may have the

same network number but different network masks. Note that this MIB

obsoletes a number of objects from RFC 1354. The reader should pay

careful attention to the STATUS field.

2. 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 [1], - the mechanisms used

for describing and naming objects for the purpose of

management.

o the MIB-II, STD 17, RFC 1213 [2], - the core set of

managed objects for the Internet suite of protocols.

o the protocol, RFC 1157 [6] and/or RFC 1905 [4], - the

protocol for accessing managed information.

Textual conventions are defined in RFC 1903 [3], and conformance

statements are defined in RFC 1904 [5].

The Framework permits new objects to be defined for the purpose of

experimentation and evaluation.

2.1. 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 object type is named

by an OBJECT IDENTIFIER, an administratively...
