<para>When true, the gateway will be requested from the DHCP server and added to the routing
table with a metric of 1024, and a scope of <option>link</option>. When unset, the value
specified with <varname>UseRoutes=</varname> is used.</para>
<para>When true, and the DHCP server provides a Router option, the default gateway based on the
router address will be configured. Defaults to unset, and the value specified with
<varname>UseRoutes=</varname> will be used.</para>
<para>Note, when the server provides both the Router and Classless Static Routes option, and
<varname>UseRoutes=</varname> is enabled, the Router option is always ignored regardless of this
setting. See <ulink url="https://datatracker.ietf.org/doc/html/rfc3442">RFC 3442</ulink>.</para>
