Whether you want to redist mostly depends on what you want to happen
when interfaces go up or down, and the ability of your network to
reconverge (fairly) promptly after the routing changes.
If nobody is relying on the IGP for multi-homing, it probably doesn't
matter. If they are, you need to redistribute something. You probably
don't want to redistribute into your EGP, since flapping is punishable.
one case:
redist connected into ospf
redist static excluding /32's into ospf (optional)
us null-routed static aggregates with geographic mapping
don't redist into bgp
use bgp network statments for aggregates
it's mostly a question of what skeleton is needed to make your network
work vs. how much hair you want to pull out when it goes weird. 8-)
