Definition:
A route to a particular destination.
Access:
read-write.
Status:
mandatory.
We now consider the individual components of each route in the
IP Routing table:
OBJECT:
-------
ipRouteDest { ipRouteEntry 1 }
Syntax:
IpAddress
Definition:
The destination IP address of this route. An entry with
a value of 0.0.0.0 is considered a default route.
Multiple routes to a single destination can appear in the
table, but access to such multiple entries is dependent
on the table-access mechanisms defined by the network
management protocol in use.
Access:
read-write.
Status:
mandatory.
OBJECT:
-------
ipRouteIfIndex { ipRouteEntry 2 }
Syntax:
INTEGER
Definition:
The index value which uniquely identifies the local
interface through which the next hop of this route should
be reached. The interface identified by a particular
value of this index is the same interface as identified
by the same value of ifIndex.
Access:
read-write.
Status:
mandatory.
OBJECT:
-------
ipRouteMetric1 { ipRouteEntry 3 }
Syntax:
INTEGER
Definition:
The primary routing metric for this route. The semantics
of this metric are determined by the routing-protocol
specified in the route's ipRouteProto value. If this
metric is not used, its value should be set to -1.
Access:
read-write.
Status:
mandatory.
OBJECT:
-------
ipRouteMetric2 { ipRouteEntry 4 }
Syntax:
INTEGER
Definition:
An alternate routing metric for this route. The
semantics of this metric are determined by the routing-
protocol specified in the route's ipRouteProto value. If
this metric is not used, its value should be set to -1.
Access:
read-write.
Status:
mandatory.
OBJECT:
-------
ipRouteMetric3 { ipRouteEntry 5 }
Syntax:
INTEGER
Definition:
An alternate routing metric for this route. The
semantics of this metric are determined by the routing-
protocol specified in the route's ipRouteProto value. If
this metric is not used, its value should be set to -1.
Access:
read-write.

OBJECT:
-------
ipRouteNextHop { ipRouteEntry 7 }
Syntax:
IpAddress
Definition:
The IP address of the next hop of this route. (In the
case of a route bound to an interface which is realized
via a broadcast media, the value of this field is the
agent's IP address on that interface.)
Access:
read-write.

OBJECT:

ipRouteType { ipRouteEntry 8 }
Syntax:

invalid(2), -- an invalidated route
-- route to directly
direct(3), -- connected (sub-)network
-- route to a non-local
remote(4) -- host/network/sub-network
}
Definition:
The type of route.
Setting this object to the value invalid(2) has the effect of
invalidating the corresponding entry in the ipRoutingTable
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 ipRouteType object.

intended to imply that hosts should support those
protocols.

Status:

OBJECT:
-------
ipRouteAge { ipRouteEntry 10 }
Syntax:
INTEGER
Definition:
The number of seconds since this route was last updated
or otherwise determined to be correct. Note that no
semantics of "too old" can be implied except through
knowledge of the routing protocol by which the route was
learned.
Access:
read-write.
Status:
mandatory.
OBJECT:
-------
ipRouteMask { ipRouteEntry 11 }
Syntax:
IpAddress
Definition:
Indicate the mask to be logical-ANDed with the
destination address before being compared to the value in
the ipRouteDest field. For those systems that do not
support arbitrary subnet masks, an agent constructs the
value of the ipRouteMask by determining whether the value
of the correspondent ipRouteDest field belong to a
class-A, B, or C network, and then using one of:
mask network
255.0.0.0 class-A
255.255.0.0 class-B
255.255.255.0 class-C
If the value of the ipRouteDest is 0.0.0.0 (a default
route), then the mask value is also 0.0.0.0. It should
be noted that all IP routing subsystems implicitly use
this mechanism.
Access:
read-write.
Status:

5.4.3. The IP Address Translation table
The Address Translation tables contain the IpAddress to "physical"
address equivalences. Some interfaces do not use translation tables
for determining address equivalences (e.g., DDN-X.25 has an
algorithmic method); if all interfaces are of this type, then the
Address Translation table is empty, i.e., has zero entries.
OBJECT:

addresses to physical addresses.

Translation table entry:

ipNetToMediaType { ipNetToMediaEntry 4 }
Syntax:
INTEGER {
other(1), -- none of the following
invalid(2), -- an invalidated mapping
dynamic(3),
static(4)
}
Definition:
The type of mapping.
Setting this object to the value invalid(2) has the effect of
invalidating the corresponding entry in the ipNetToMediaTable.
That is, it effectively disassociates the interface identified
with said entry from the mapping 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 ipNetToMediaType object.

5.9. The Transmission Group
Based on the transmission media underlying each interface on a
system, the corresponding portion of the Transmission group is
mandatory for that system.
When Internet-standard definitions for managing transmission media
are defined, the transmission group is used to provide a prefix for
the names of those objects.
Typically, such definitions reside in the experimental portion of the
MIB until they are "proven", then as a part of the Internet
standardization process, the definitions are accordingly elevated and
a new object identifier, under the transmission group is defined. By
convention, the name assigned is:
type OBJECT IDENTIFIER ::= { transmission number }
where "type" is the symbolic value used for the media in the ifType
column of the ifTable object, and "number" is the actual integer
value corresponding to the symbol.
5.10. The SNMP Group
Implementation of the SNMP group is mandatory for all systems which
support an SNMP protocol entity. Some of the objects defined below
will be zero-valued in those SNMP implementations that are optimized
to support only those functions specific to either a management agent
or a management client.
