roa_check not re-evaluating after roa table update

[Stefan Plug]

Hi guys,

Bird 1.6.3

Just testing about with the RPKI roa_check and it seems that my routes are not 
being re-evaluated after a "configure" when my roa table is updated.
I do this check during the import phase so the routes are already in the table 
once I update the roa table.

simple check example:
        roa table roa_table {
                roa 200.0.0.0/24 max 24 as 1340;
        }
        if (roa_check( roa_table, net, bgp_path.last)) = ROA_INVALID then {
            if hardFilterRPKI > 0 then {
                return false;
            }
            else {
                return true;
            }
        }

Now I update the config to:
        roa table roa_table {
                roa 200.0.0.0/24 max 24 as 1340;
                roa 200.0.0.0/24 max 24 as 1339;
        }

When I now reconfigure BIRD this makes no changes at all. If I restart BIRD and 
thus the routes get re-sent then they do both get through the check as
expected. when adding/deleting roa entries using the command line I see the 
same behaviour.

Do note when I change the "hardFilterRPKI" which decides to actually filter or 
not, then the routes DO get re-evaluated like they should.

Can anyone else also confirm this behaviour? Am I doing something wrong?
