Routes only work when you can reach the next hop. That is, if you try
to add a route through an interface that is not up, the command will
fail and the route will not be added. If you want a route to be added
when an interface comes up, there is already a place to do that.
However, as others have pointed out you shouldn't expect multiple
concurrent default routes to do something useful - but if you have
multiple interfaces you can configure them both to add default routes
and bring only one up at a time.
