Correct replacement for 'birdc reload in all' in BIRD 3.1?

[Robert Scheck]

Hello,

I'm currently running the following commands in a systemd.service as part
of a systemd.timer:

 - rpki-client -B -c -j -m -o
 - bird -p -c /var/lib/rpki-client/bird
 - birdc configure soft
 - birdc reload in all

Since upgrading from BIRD 2.16 to 3.1, the last command fails. However,
https://gitlab.nic.cz/labs/bird/-/blob/stable-v3.1/doc/migration-bird3.md
mentions just:

> "Reload of filters is now done by reload filters command, contrary to
> just reload in BIRD 2.

Am I overlooking something? What's the correct replacement command for BIRD
3.1?


Regards,
