if you have a /16 why would it be broken down to /24? i would assume the only reason you advertise /24 is because that is the size of your assignment from the NIC, in which case you cannot advertise the /16.
if you do own the /16 then yes of course you can advertise it.
Stephen, you neglected to look at the big picture. The "organization" has the /16 but has sites spread out all over the planet and has assigned /24's to them. Additionally, they connect into the global net via diverse providers.
Ah, I got -snip- happy there :) in that case I would question the logic of being given a large address block only to break it into pieces all over the world. I'd wonder why they dont take address space from a regional provider - if its only /24 it cant be that mission critical for bgp and multihoming...
