This article will go through the proper way to set a static route on Linux.
1. Get Interface Name:
Run an ifconfig or ip addr in order to grab the interface name, that you want to set the route traffic to go through.
ifconfig
eth0 Link encap:Ethernet HWaddr 08:00:27:40:78:ec
inet addr:10.0.0.24 Bcast:10.79.0.255 Mask:255.255.255.0
inet6 addr: 2606:a000:4f85:ac00:a00:27ff:fe40:78ec/64 Scope:Global
inet6 addr: fe80::a00:27ff:fe40:78ec/64 Scope:Link
UP BROADCAST RUNNING MULTICAST MTU:1500 Metric:1
RX packets:177 errors:0 dropped:30 overruns:0 frame:0
TX packets:82 errors:0 dropped:0 overruns:0 carrier:0
collisions:0 txqueuelen:1000
RX bytes:17929 (17.5 KiB) TX bytes:9417 (9.1 KiB)
2. Create Route File:
Create a new file named /etc/sysconfig/network-scipts/route-eth0
This file is titled route-eth0 to correspond to the adapter that we want to send the
through in order to get to the selected route.
10.2.0.0/16 via 10.0.0.24
3. Restart the Network Services:
systemctl restart network.service
4. Verify the route:
route -n

2. Edit the interfaces file:
Open the /etc/network/interfaces file, and add the route statements to the end
of the interface block.
auto eth0
iface eth0 inet Static
address 10.0.0.24
netmask 255.255.0.0
gateway 10.0.0.1
up route add -net 10.2.0.0 netmask 255.255.0.0 gw 10.0.0.24
3. Restart the Network Services:
systemctl restart networking.service
4. Verify the route:
route -n
