DESCRIPTION
"The MIB module for the management of CIDR multipath IP
Routes.
Copyright (C) The Internet Society (2006). This version
of this MIB module is a part of RFC 4292; see the RFC
itself for full legal notices."
REVISION "200602010000Z"
DESCRIPTION
"IPv4/v6 version-independent revision. Minimal changes
were made to the original RFC 2096 MIB to allow easy
upgrade of existing IPv4 implementations to the
version-independent MIB. These changes include:
Adding inetCidrRouteDiscards as a replacement for the
deprecated ipRoutingDiscards and ipv6DiscardedRoutes
objects.
Adding a new conformance statement to support the
implementation of the IP Forwarding MIB in a
read-only mode.
The inetCidrRouteTable replaces the IPv4-specific
ipCidrRouteTable, its related objects, and related
conformance statements.
Published as RFC 4292."

SYNTAX IpAddress
MAX-ACCESS read-only
STATUS obsolete
DESCRIPTION
"The destination IP address of this route. An entry
with a value of 0.0.0.0 is considered a default route.
This object may not take a Multicast (Class D) address
value.
Any assignment (implicit or otherwise) of an instance
of this object to a value x must be rejected if the
bitwise logical-AND of x with the value of the
corresponding instance of the ipForwardMask object is
not equal to x."
::= { ipForwardEntry 1 }
ipForwardMask OBJECT-TYPE
SYNTAX IpAddress
MAX-ACCESS read-create
STATUS obsolete
DESCRIPTION
"Indicate the mask to be logical-ANDed with the
destination address before being compared to the value
in the ipForwardDest field. For those systems that do
not support arbitrary subnet masks, an agent constructs
the value of the ipForwardMask by reference to the IP
Address Class.
Any assignment (implicit or otherwise) of an instance
of this object to a value x must be rejected if the
bitwise logical-AND of x with the value of the
corresponding instance of the ipForwardDest object is
not equal to ipForwardDest."

-- The following convention is included for specification
-- of TOS Field contents. At this time, the Host Requirements
-- and the Router Requirements documents disagree on the width
-- of the TOS field. This mapping describes the Router
-- Requirements mapping, and leaves room to widen the TOS field
-- without impact to fielded systems.
ipForwardPolicy OBJECT-TYPE
SYNTAX Integer32 (0..2147483647)
MAX-ACCESS read-only
STATUS obsolete
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 ipForwardProto
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.

SYNTAX INTEGER {

MAX-ACCESS read-create
STATUS obsolete
DESCRIPTION
"The type of route. Note that local(3) refers to a
route for which the next hop is the final destination;
remote(4) refers to a route for which the next hop is
not the final destination.
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 identified 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 currently in use. Proper
interpretation of such entries requires examination of
the relevant ipForwardType object."

not present, its value should be set to the OBJECT
IDENTIFIER { 0 0 }, which is a syntactically valid
