You need to add "borrow" to your default queue. That's where the spare
bandwidth is, not the root queue. As it is defined now, your child
queues below extranet can only borrow bandwidth from each other. If you
add borrow to your default queue, extranet can borrow from intranet and
share that to its child queues.
