Using the IP Routing Table Window

Figure7 -1. IP Routing Table Window
The IP Routing Table displays the following fields:
Destination
The destination IP address of this route, according to the ipRouteDest. 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. A gateway determ ines the route in which to send an IP datagram
by checking its IP Routing Table. Each entry in the table represents a different
route to a gateway. The routing table points to gateways that can be reached
across a single network.
Next Hop
The IP address of the next hop of this route, according to the ipRouteNextHop. 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. If the datagram’s
ultimate destination is on a directly connected network, the next hop IP address is
the same as the datagram’s destination IP address. The next hop specifies a
gateway that can route the datagram closer to its final destination.
Route Age
The number of seconds since this route was last updated or otherwise determined
to be correct, according to the ipRouteAge. No semantics of ‘too old’ can be implied
except through knowledge of the routing protocol by which the route was
learned.
