Getting dynamic IP when starting dhcpcd with Static IP

Hi!

I have issue with starting dhcpcd with static ip, from command line.
I start dhcpcd with command: "dhcpcd wlan0 --ipv4only --static ip_address=
10.30.2.121/21 --static routers=10.30.0.1 --static
domain_name_servers="10.30.0.101 10.30.0.120""
But dhcpcd is still doing discover/request, and uses that address as
static. Am I missing something?

I see the same behavior on 6.11.3 and 7.2.2 (system running Yocto). Seems
as I get this when I don't have any lease-file for the SSID that I connect
to.

Traces:
   dhcpcd[2497]: DUID 00:01:00:01:24:e6:df:a4:00:01:3e:3d:f2:31
