Sorry, getting a default route from the provider was assumed  in my
mind and not in the email.  It goes back to routers that can take only
256k routes ... they cant take full tables these days, so they just
ditch the smaller blocks.  The default route still work for
reachability .... but not route optimization at the edge.
