(with route-map, or appropriate filters as necessary that vary by vendor)

No argument with the principles here but why do you need to redistribute
connected interfaces into your IGP *and* into iBGP? Overkill, surely?


In fact, you not only don't need to do so, you want to avoid doing so.
This simply pollutes BGP and you'll need to remove it later at the domain
border where you're aggregating anyhow.
