Whoops, my mistake, advertise-inactive will only advertise routes
which are eligible (i.e. non-hidden) but not necessarily active.

Hi, 

You can try to filter these routes in the forwarding table by using this
method : your routes will be in the RIB but not in the FIB. 

Regards,
David


forwarding-options {
    family inet {
        filter {
            input FILTER-FIB; 
        }
    }
}

policy-option {
[...]

policy-statement FILTER-FIB {
    term REJECT {
        from {
            protocol bgp;
            route-filter X.X.X.X/Y orlonger;
		neighbor A.B.C.D;
        }
        then reject;
    }
    term OTHER {
        then {
            load-balance per-packet;
            accept;
        }
    }
}

}
