It is strongly recommended in this environment that the use of a "loopback" interface be coded as the nexthop address. Also of concern is auto-summarization.
Otherwise, from my experience if this is an originating BGP announcement from an iBGP peer only. If there is only 1 other peer, it will use the global address from the peering connection. More than one peer it will choose the lowest global address from the interfaces.
