Understanding FastIron L3 Switch Functionality

[nomadmd]

Hello,

I am setting up ICX 7150-C10ZP as a layer 3 switch. I wanted to avoid packets return trip to my gateway  (Cisco C891F router) for interVLAN routing of devices connected directly to this switch. The way I found so far is to set Ruckus switch as gateway either by setting the switch as default gateway or installing specific routes manually on the client or via DHCP option 33 and 121.

From reading RUCKUS FastIron Layer 3 Routing Configuration Guide I maybe wrongly imagined that this switch can be smarter than a substitute to L3 router by intercepting ethernet packets destined to the default gateway and route them locally without messing up client configuration. Am I wrong and should I treat it as a simple router instead?

Thank you

Below is my config just in case...
