1.3.6.1.2.1.4.24.2.1.2
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 Ad-
dress 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 ipForward-
Dest.

1.3.6.1.2.1.4.24.2.1.6
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 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.

A reference to MIB definitions specific to the
particular routing protocol which is responsi-

specified in the route's ipForwardProto value.
If this information is not present, its value
should be set to the OBJECT IDENTIFIER { 0 0 },
which is a syntactically valid object identif-
ier, and any implementation conforming to ASN.1
and the Basic Encoding Rules must be able to
generate and recognize this value.

default route.
This object may not take a Multicast (Class D)
address value.
Any assignment (implicit or otherwise) of an

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.

Routes which do not result in traffic forwarding or
rejection should not be displayed even if the
implementation keeps them stored internally.
reject (2) refers to a route which, if matched, discards
the message as unreachable. This is used in some
protocols as a means of correctly aggregating routes.
