O/S forwarding table window
The O/S forwarding table window lists forwarding information for all routes.
$ ,7A'& ,$( ,
Destination (ipRouteDest)
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.
Mask (ipRouteMask)
Indicates 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 belongs to a
Class A, B, or C network, and then using the appropriate mask from table 3 on page 77.
Next Hop (ipRouteNextHop)
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.)
Interface (ipRouteIfIndex)
The index value that 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.
Type (ipRouteType)
One of the following route types:
• other(1)—none of the following
• invalid(2)—an invalidated route
