An external BGP prefix is advertised to iBGP peers with the next hop
preserved. In some cases the next hop may not be reachable by an iBGP peer
so you would use the neighbor next-hop-self command. That would change the
next hop for the prefix to the advertising router thus making the next hop
reachable and the learned path valid.
