Not necessarily, unless you've configured the "Distribution" routers as such. > The dists are neighbored with > the RASen, but the RASen are not currently considered > route reflector clients.

Ideally, centralizing the route reflector function would be best, i.e., if you core routers are running that function, then have your routers run iBGP with your core routers. However, this may be moot if the ASCII diagram you sent through is your actual topology, i.e., your RAS's have a single link to your "Distribution" routers. Cheers, Mark.
