100 eth1
200 eth2
6. For each interface enable PBR. Below is an example for eth1 and needs to be repeated for eth2.
ScaleIO-172-16-33-12:~ # ip route flush table eth1
ScaleIO-172-16-33-12:~ # ip route add 172.16.34.0/24 dev eth1 proto kernel scope
link table eth1
ScaleIO-172-16-33-12:~ # ip route add default via 172.16.34.253 dev eth1 table
eth1
ScaleIO-172-16-33-12:~ # ip rule add from 172.16.34.0/24 lookup eth1
7. Verify the route tables and ip rules to ensure a new default route for each interface has been created.
ScaleIO-172-16-33-12:~ # ip route list table eth1
default via 172.16.34.253 dev eth1
172.16.34.0/24 dev eth1 proto kernel scope link
ScaleIO-172-16-33-12:~ # ip rule
0: from all lookup local
32763: from 172.16.35.0/24 lookup eth2
32764: from 172.16.34.0/24 lookup eth1
32765: from all lookup main
32766: from all lookup default
8. Finally, validate the solution is working by repeating the ping test.
ScaleIO-172-16-33-12:~ # tcpdump -n -i eth2 icmp
tcpdump: verbose output suppressed, use -v or -vv for full protocol decode
listening on eth2, link-type EN10MB (Ethernet), capture size 96 bytes
