Hi,

In bird (3.0.0 version) I am seeing a strange behavior which is not the case with the previous bird version I was using (2.13.1)

In the routing configuration in case of multipath routes if the addresses are not sorted bird doesn't generate the route in the system and warning `<WARN> static1.ipv4: Ignoring unsorted multipath route 0.0.0.0/0` appears in the log

an example:
protocol static {
                ipv4 { table ipv4Table_14; };
                route 0.0.0.0/0  via 10.17.3.123 bfd
                                 via 10.17.3.122 bfd;
                }

If the addresses are set in an ascending order then the route is generated.

Logs:
