Routers that learn a route over IBGP need to know where the next hop
address for route from other AS points to. Since this can't be a loopback
address and you typically don't run an IGP on subnets between border
routers in your AS and a remote AS, you need to either set next-hop-self
on all IBGP sessions or redistribute connected in your IGP.
