Add route & Delete route
You can add routing and gateway settings like below.
route add -net 192.168.63.0/24 gw 192.168.163.1
Or if you want to do permanent routing, you can create route file like below.
[[email protected] ~]# [[email protected] network-scripts]# cat route-eth1 192.168.63.0/24 via 192.168.163.1 dev eth1 192.168.161.0/24 via 192.168.161.1 dev eth0
If you create routing file like above then you can restart network service like below.
[[email protected] network-scripts]# service network restart
then Routing will be like below.
[[email protected] network-scripts]# route Kernel IP routing table Destination Gateway Genmask Flags Metric Ref Use Iface default 192.168.161.1 0.0.0.0 UG 0 0 0 eth0 link-local * 255.255.0.0 U 0 0 0 ibbond0 192.168.161.0 * 255.255.255.0 U 0 0 0 eth0 192.168.16.0 * 255.255.255.0 U 0 0 0 ibbond0 192.168.18.0 * 255.255.255.0 U 0 0 0 veth1 192.168.19.0 192.168.18.1 255.255.255.0 UG 0 0 0 veth1 192.168.63.0 192.168.163.1 255.255.255.0 UG 0 0 0 eth1 192.168.163.0 * 255.255.255.0 U 0 0 0 eth1
