ipAdEntNetMask OBJECT-TYPE
SYNTAX IpAddress
ACCESS read-only
STATUS mandatory
DESCRIPTION
"The subnet mask associated with the IP address of
this entry. The value of the mask is an IP
address with all the network bits set to 1 and all
the hosts bits set to 0."
::= { ipAddrEntry 3 }
ipAdEntBcastAddr OBJECT-TYPE
SYNTAX INTEGER
ACCESS read-only
STATUS mandatory
DESCRIPTION
"The value of the least-significant bit in the IP
broadcast address used for sending datagrams on
the (logical) interface associated with the IP
address of this entry. For example, when the
Internet standard all-ones broadcast address is
used, the value will be 1. This value applies to
both the subnet and network broadcasts addresses
used by the entity on this (logical) interface."
::= { ipAddrEntry 4 }
ipAdEntReasmMaxSize OBJECT-TYPE
SYNTAX INTEGER (0..65535)
ACCESS read-only
STATUS mandatory
DESCRIPTION
"The size of the largest IP datagram which this
entity can re-assemble from incoming IP fragmented
datagrams received on this interface."

DESCRIPTION
"This entity's IP Routing table."

ipRouteDest OBJECT-TYPE
SYNTAX IpAddress
ACCESS read-write
STATUS mandatory
DESCRIPTION
"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."
::= { ipRouteEntry 1 }
ipRouteIfIndex OBJECT-TYPE
SYNTAX INTEGER
ACCESS read-write
STATUS mandatory
DESCRIPTION
"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."
::= { ipRouteEntry 2 }
ipRouteMetric1 OBJECT-TYPE
SYNTAX INTEGER
ACCESS read-write
STATUS mandatory
DESCRIPTION
"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."
::= { ipRouteEntry 3 }
ipRouteMetric2 OBJECT-TYPE
SYNTAX INTEGER
ACCESS read-write
STATUS mandatory
DESCRIPTION
"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."
::= { ipRouteEntry 4 }
ipRouteMetric3 OBJECT-TYPE
SYNTAX INTEGER
ACCESS read-write
STATUS mandatory
DESCRIPTION
"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."
::= { ipRouteEntry 5 }
ipRouteMetric4 OBJECT-TYPE
SYNTAX INTEGER
ACCESS read-write
STATUS mandatory
DESCRIPTION
"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."
::= { ipRouteEntry 6 }
ipRouteNextHop OBJECT-TYPE
SYNTAX IpAddress
ACCESS read-write
STATUS mandatory
DESCRIPTION
"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.)"
::= { ipRouteEntry 7 }
ipRouteType OBJECT-TYPE
SYNTAX INTEGER {
other(1), -- none of the following
invalid(2), -- an invalidated route
-- route to directly
direct(3), -- connected (sub-)network
-- route to a non-local
indirect(4) -- host/network/sub-network
}
ACCESS read-write
STATUS mandatory
DESCRIPTION
"The type of route. Note that the values
direct(3) and indirect(4) refer to the notion of
direct and indirect routing in the IP
architecture.
Setting this object to the value invalid(2) has
the effect of invalidating the corresponding entry
in the ipRouteTable object. That is, it
effectively dissasociates 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."

SYNTAX INTEGER {
other(1), -- none of the following
-- non-protocol information,
-- e.g., manually configured
local(2), -- entries
-- set via a network
netmgmt(3), -- management protocol
-- obtained via ICMP,

}
ACCESS read-only
STATUS mandatory
DESCRIPTION
"The routing mechanism via which this route was
learned. Inclusion of values for gateway routing
protocols is not intended to imply that hosts
should support those protocols."
::= { ipRouteEntry 9 }
ipRouteAge OBJECT-TYPE
SYNTAX INTEGER
ACCESS read-write
STATUS mandatory
DESCRIPTION
"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."
::= { ipRouteEntry 10 }
ipRouteMask OBJECT-TYPE
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 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."
::= { ipRouteEntry 11 }
ipRouteMetric5 OBJECT-TYPE
SYNTAX INTEGER
ACCESS read-write
STATUS mandatory
DESCRIPTION
"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."
::= { ipRouteEntry 12 }
ipRouteInfo OBJECT-TYPE
SYNTAX OBJECT IDENTIFIER
ACCESS read-only
STATUS mandatory
DESCRIPTION
"A reference to MIB definitions specific to the
particular routing protocol which is responsible
for this route, as determined by the value
specified in the route's ipRouteProto value. If
this information is not present, its value should
be set to the OBJECT IDENTIFIER { 0 0 }, which is
a syntatically valid object identifier, and any
conformant implementation of ASN.1 and BER must be
able to generate and recognize this value."
