Status of this Memo
This document is an Internet Draft. Internet Drafts are
working documents of the Internet Engineering Task Force
(IETF), its Areas, and its Working Groups. Note that other
groups may also distribute working documents as Internet
Drafts.
Internet Drafts are valid for a maximum of six months and may
be updated, replaced, or obsoleted by other documents at any
time. It is inappropriate to use Internet Drafts as reference
material or to cite them other than as a "work in progress".

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.

2. The SNMPv2 Network Management Framework
The SNMPv2 Network Management Framework consists of four major
components. They are:
o RFC 1441 which defines the SMI, the mechanisms used for
describing and naming objects for the purpose of
management.
o RFC 1213 defines MIB-II, the core set of managed objects
for the Internet suite of protocols.
o RFC 1445 which defines the administrative and other
architectural aspects of the framework.
o RFC 1448 which defines the protocol used for network
access to managed objects.
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 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 refer to the
object type.

draft IP Forwarding Table MIB March 1995
3. Overview
The MIB consists of two tables and two global objects.
(1) The object ipForwardNumber indicates the number of
current routes. This is primarily to avoid having to
read the table in order to determine this number.
(2) The ipForwardTable updates the RFC 1213 ipRouteTable to
display multipath IP Routes. This is in turn obsoleted
by the ipCidrRouteTable.
(3) The ipCidrRouteTable updates the RFC 1213 ipRouteTable to
display multipath IP Routes having the same network
number but differing network masks.

DESCRIPTION
"The general set of conditions that would cause
the selection of one multipath route (set of
next hops for a given destination) is referred
to as 'policy'.
Unless the mechanism indicated by ipForwardPro-
to specifies otherwise, the policy specifier is
the IP TOS Field. The encoding of IP TOS is as
specified by the following convention. Zero
indicates the default path if no more specific
policy applies.

destination; remote(4) refers to a route for
which the next hop is not the final destina-
tion.
Setting this object to the value invalid(2) has
the effect of invalidating the corresponding
entry in the ipForwardTable object. That is,
it effectively disassociates the destination
identified with said entry from the route iden-
tified with said entry. It is an
implementation-specific matter as to whether
the agent removes an invalidated entry from the
table. Accordingly, management stations must
be prepared to receive tabular information from
agents that corresponds to entries not current-
ly in use. Proper interpretation of such en-
tries requires examination of the relevant ip-
ForwardType object."
