- "The destination IP address of this route. An

- default route.
-
- This object may not take a Multicast (Class D)
- address value.
-

- rejected if the bitwise logical-AND of x with

- ipForwardMask object is not equal to x."

- SYNTAX IpAddress
- ACCESS read-write
- STATUS mandatory
- 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 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."

- -- 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 INTEGER
- ACCESS read-only
- STATUS mandatory
- 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.

- other (1), -- not specified by this MIB

- }
- ACCESS read-write
- STATUS mandatory
- 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 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."

- specified in the route's ipForwardProto value.
- If this information is not present, its value
- should be set to the OBJECT IDENTIFIER { 0 0 },
