'route_default' variable is used with following eval line.
Because '${i}' is element of '${static_routes}',
in this case 'route_${i}' is substituted for 'route_default'.
I referred to 'network_pass1' function of /etc/rc.network,
it is around 330th line.

		# Set up any static routes if specified
		if [ -n "${static_routes}" ]; then
			for i in ${static_routes}; do
				eval route_args=\$route_${i}
				route add ${route_args}
			done
		fi

When I do hot-plug of PC-card Ethernet and USB Ethernet with
more than one environment, former route is left and may become
a problem. Therefore I was able to control it with
'removable_route_flush' variable.
There is a method to add 'removable_route_flush=NO' to
/etc/defaults/rc.conf, but which is better compared with below patch?
