Typically if you want put 3 ip addresses in the same subnet on a network usually you use a single network adaptor and add extra VIPs on it.
see: https://www.jamescoyle.net/how-to/307-create-a-virtual-ip-address-in-linux eth0:1 for the device names it the 1st vip, :1 as the 2nd vip and so on. They all exist on the same adaptor. with the same network on all 3 what interface it goes out can be different than the one it came in and this can cause significant issues on the network.
