Well, I hope this isn't for a real-world network; redistributing BGP into an
IGP is a big no-no. :)
What you specified below should be enough to get all the routes in that
match the ACL. The fact that you are a transit doesn't really have any
bearing on the route redistribution.
You'd probably be better off with using a prefix list in lieu of a plain ol'
ACL. It escapes be what the "destination" part of the ACL does in
redistribution, but the source of permit ip host x.x.y.y will end up only
permitting a /32 route to go from BGP into your IGP. Scott... Care to
clarify?
