I always recommend setting the NEXT_HOP attribute to 'self' 
for all iBGP sessions at the (peering) edge, and using your 
IGP to provide reachability to all Loopback addresses in the 
network. This scales quite well.

And while IGP/BGP redistribution may be possible, we tend to 
avoid it as much as possible.

Cheers,

Mark.
