Hi Arman,
If you want to route part1 to ISP1 and Part 2 to ISP2. You should have
the following rules
ip rule add from 193.168.3.0/25 to 0.0.0.0/0 table 100
ip route add default via 192.168.1.1 table 100
ip rule add from 192.168.3.128/25 to 0.0.0.0/0 table 200
ip route add default via 203.81.213.1 table 200
