And redistribution can lead to accidentally matching things you didn't mean 
to match, which is usually a lot worse. If you have to ask, I personally 
recommend erring on the side of caution and use an explicit network 
statement. :)

But in this case it doesn't matter, because 0/0 is actually a special case 
for IOS.
