Multiple IP addresses for multiple NICs in the same network segment in Linux

Two NICs may be disconnected in the same network segment, but the IP addresses that ping the NIC can still be pinged. The two IP addresses are directed to the same MAC address.

Eth0 192.168.1.10
Eth1 192.168.1.11

Echo "252 net2">/etc/iproute2/rt_tables
Echo "251 net3">/etc/iproute2/rt_tables

IP Route add 192.168.1.0/24 Dev eth0 SRC 192.168.1.10 table net2
IP Route add 192.168.1.0/24 Dev eth1 SRC 192.168.1.253 table net3
IP Route add default Dev eth0 table net2
IP Route add default Dev eth1 table net3

IP rule add from 192.168.1.10 table net2
IP rule add from 192.168.1.11 table net3

Ping, and then ARP verifies that the MAC address is different.
