Inclusion of values for gateway routing protocols is not intended to imply that hosts should support
those protocols.
ipRouteAge 1.3.6.1.2.1.4.21.1.10
The number of seconds since this route was last updated or otherwise determined to be correct.
Older semantics cannot be implied except through knowledge of the routing protocol by which the
route was learned.
Not supported.
ipRouteMask 1.3.6.1.2.1.4.21.1.11
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 the following:
NOTE
If the value of the ipRouteDest is 0.0.0.0 (default route), then the mask value is also 0.0.0.0.
All IP routing subsystems implicitly use this mechanism.
ipRouteMetric5 1.3.6.1.2.1.4.21.1.12
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.
ipRouteInfo 1.3.6.1.2.1.4.21.1.13
A reference to MIB definitions specific to the particular routing protocol that 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 syntactically valid object
identifier; any conferment implementation of ASN.1 and BER must be able to generate and
recognize this value.
ipNetToMediaTable 1.3.6.1.2.1.4.22
The IP Address Translation table used for mapping from IP addresses to physical addresses.
