In-Depth Information
that has more than one gateway configured, the gateway metric
allows the OS to determine
which gateway will be used first—a gateway with a metric of 1 will be used before a gateway
with a metric of 2, and so forth. To optimize network performance, you should configure the
gateway attached to the highest-speed link with the lower gateway metric. This also allows you
to create fault tolerance by configuring a secondary gateway attached to a lower-speed link.
For example, if the gateway attached to a T-1 line is unavailable, the device can transmit network
packets over a gateway attached to a lower-speed ISDN line.
In Windows Server 2003, the gateway metric is configured automatically; the NIC attached
to the higher-speed link receives the lower (and therefore preferred) metric. To manually
control which gateway receives traffic first, you can configure a gateway metric using any of the
methods described in this section.
