Help connecting ASUS GT-AXE16000 to L3 Switch

[mbze430]

I am going to assuming this requires CLI as I don't think the GUI is able to do this.
I need to be able to configure one of the 10Gb port as a routing port.
I am completely NOT familiar with the ASUS CLI syntax.

My current set is as follow in the diagram, but it's not quite working as expected.

all my VLAN subnet isn't able to get to 172.30.0.1 without a static default route in the Core.
if I add in a default route (0.0.0.0/0 to gateway 172.30.0.1) to my core switch (SONiC) it completely drops all routing. Not even sure why that's happening.
But normally with a multilayer switch setup I would configure the Brocade TE 1/0/46 as:
#no switchport
#ip address 192.0.0.1 255.255.255.252

And somehow make one of the ASUS 10Gb port 192.0.0.2 255.255.255.252

so I can route through.

My question is how can I make that port as such and keep it permanent?

Any help would be great.

NOTE: "Router On A Stick" is not an option. Primary reason is that my SONiC (Broadcom Tomahawk) can do 3.1Tb line speed. The ASUS VLAN is super limited when it comes to VLAN assignment.

You're well beyond the capabilities of a consumer router/ap...

Reflect on your network design, and you'll find that Asus likely is out of scope...
