The only way to get from one bridge to another is by routing so if there
is no route then there's no way to get packets (or frames) to leap from
one bridge to another. (And if you're using separate vlans then you'd
need a machine on both that is prepared to route the packets.)
Of course, testing is paramount. No amount of hypothesising is going to
help if you haven't tested.
