A default route is typically used on a gateway or router to an internet, or on a gateway or router that uses another routing protocol, whose routes are not reported to other local gateways or routers.

METRIC=1,DISP=PERM
net 0.0.0.0 gateway 9.67.112.1 metric 1 passive
Only one default route to a destination gateway or router can be specified. For an NCP client, NCPROUTE currently does not support multiple default routes.
