Force static IP on DHCP interface

I have bridged ether* and wlan1, and set up DHCP server on the bridge. I want use static IP for my PC on ehter1 (because DHCP setup during boot takes about 5 seconds) but still leave DHCP on ether1 (just for case). Can I simply ignore DHCP leasing procedure and manually set up static IP when booting PC (the IP from Microtik’s DHCP address pool)?

As long as your pc has an IP address inside the range routed by the routerboard it is ok.
Nevertheless it is adviced to use a static address outside the DHCP range.

You can configure a static IP it should be within your network range but NOT from the DHCP address pool.

Thanks!
