Linux has EVPN support. Or you could use network switches with EVPN support.

EVPN will let each server or direct connected switch be a hidden layer 3
gateway. The application will not know about it and it will appear to be
layer 2 but routable like layer 3. Which means you can do anycast at layer
3. Physically the packets are moved in tunnels so you can use any layer 2
or layer 3 hardware at your choice.
