Appendix A Network Troubleshooting
Table 141 route print Command Output
OUTPUT | DESCRIPTION |
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. |

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.
Network Destination | Netmask | Gateway | Interface | Metric |
0.0.0.0 | 0.0.0.0 | 192.168.1.254 | 192.168.1.33 | 1 |
0.0.0.0 | 0.0.0.0 | 172.16.1.254 | 172.16.1.32 | 1 |
•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
Note that the metric will be set to 1 if you do not specify any.
