My routing size is too big!

Ace, thanks for that.
How do I aggregate prefixes for export, so that rather than export
lots of small prefixes, I can just export one big prefix? I'm guessing
bird is just getting all of the routes it knows about and exporting
them one-by-one (so lots of really small routes) rather than one big
Alternatively, is there a way of overriding what gets sent, so I can
just manually send one big route?
