Thanks for that one, we always just delete .empty as our we never “span” private ASNs, only have them as origins, but very cool stuff. 

Thanks Ondrej!

Hello Daz,

As far as I know there is no single command equivalent in bird, however you can achieve basically the same by running these commands in a filter


export filter {
if (source net = 22.23.24.25/23 )  then {
bgp.path.empty;
bgp.path.prepend(22232);
accept;

Hi

Note that it is 'bgp_path', not 'bgp.path'.

Also this filter resets whole bgp_path. If you want just to remove
private ASNs, you could do:

bgp_path.delete([64512..65534, 4200000000..4294967294]);
