Nothing changes in the way you advertise unicast prefixes.
However, if your purpose is to install source address filters for all 
destinations you probably want to configure the receiver w/ a policy 
such that it bypasses the automatic validation procedure.

e.g. (on the receiver)

protocols bgp group <name> {
     neighbor <x> {
         family inet {
             unicast;
             flow no-validate novalidate;
         }
     }
}

policy-options {
     replace: policy-statement novalidate {
         term a {
             from as-path local;
             then accept;
         }
     }
     replace: as-path local \"()\";
}

The policy above, will tell the receiver to accept any ibgp 
advertisement... but of course you can use any other criteria.
