If you want to delete default gateway you can execute like following script.

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.

[root@deveci02 ~]#
[root@deveci01 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.
