In this example, the 172.16.1.0 is the network address. The 172.16.1.32 is the
address of the local computer. 172.16.1.255 is the network broadcast address
which sends broadcast packets to all computers on the 172.16.1.x network.
172.16.1.254 is the default gateway.
You may have more than one 0.0.0.0 entry if your computer has two or more
network cards installed. This may casue packets to be routed somewhere
unexpected. Delete all 0.0.0.0 entries except the one that you want to use for the
default gateway. In the following example, the computer uses the first 0.0.0.0
entry for the default gateway.
• To delete the route to the default route with the gateway of 192.168.1.254,
type: route delete 0.0.0.0 mask 0.0.0.0 192.168.1.254.
• To add a route to the destination 172.16.2.0 with the subnet mask of
255.255.255.0, the next hop address of 172.16.1.250, and the cost metric of 7,
type: route add 172.16.2.0 mask 255.255.255.0 172.16.1.250 metric 7.
• To add a persistent route to the destination 172.16.3.0 with the subnet mask of
255.255.255.0 and the next hop address of 172.16.1.252, type: route -p add
172.16.3.0 mask 255.255.255.0 172.16.1.252.
Note that the metric will be set to 1 if you do not specify any.
Netmask The destination subnet mask of packets that this route entry is to
route. The subnet mask can be the apropriate subnet mask for a
network, 255.255.255.255 for a host, or 0.0.0.0 for the default
route.
Gateway The IP address of the gateway through which this computer
should send the matched packets.
Interface The IP address of an physical interface on this computer used to
send the matched packets for this route entry.
Metric The metric (hop count) of this route. Normally, the lower the
number, the faster to a destination.
Default Gateway The IP address of the gateway through which this computer sends
all the rest packets if this computer cannot find any other
matched routes for the packets.
Persistent Routes This section lists all routes that are manually configured.
