ipRouteAge
Type INTEGER
Access RW
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.
ipRouteMask
Type IpAddress
Access RW
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:
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.
