Task: Display Current Routing Table Using ip command

By using the ip command, you can setup and view static route. For example, to display current routing table you can type command:
# ip route show
Sample output: dev eth1 proto kernel  scope link  src dev eth0  proto kernel  scope link  src
default via dev eth0

You can add static route using following command:
ip route add {NETWORK} via {IP} dev {DEVICE}
For example network available via
# ip route add via dev eth1
Alternatively, you can use old good route command:
# route add -net netmask gw dev eth1

Linux Persistence Routes

The drawback of 'ip' or 'route' command is that, when Linux reboots it will forget static routes. So store them in configuration file. Static routing describes a system that does not implement adaptive routing. In these systems routes through a data network are described by fixed paths (statically). These routes are usually entered into the router by the system administrator

Red Hat (RHEL) / CentOS / Fedora Linux Persistence Static Routing

You need to open /etc/sysconfig/network-scripts/route-eth0 file to define static routes for eth0 interface:
# cat /etc/sysconfig/network-scripts/route-eth0
Sample Output:




How do I define static routing for network via router?

Open /etc/sysconfig/network-scripts/route-eth0:
# vi /etc/sysconfig/network-scripts/route-eth0
Append following line: via
Save and close the file. Restart networking:
# service network restart
Verify new routing table:
# route -n

# cat /etc/network/interfaces
