Recommendation SD-Switches

By the way: Can someone maybe please explain to me how to use the Inter-VLAN Routing settings on a SD-SWITCH 24 Port rugged by an example?

Screenshot:

If the VLAN 250 I am configuring in this screenshot for example would have e.g. 192.168.10.0/24 (and the SD-switch would have configured no fixed IP in the VLAN as not needed for ARP (see LINK)) how do I have to setup this Inter-VLAN Routing address then to reach other VLANs (e.g. VLAN ID = 220 or 230)?
