CentOS Add Route Command

by

To add a static route in CentOS, you can use the ip route add command. The syntax of the command is as follows:

sudo ip route add destination_network/subnet_mask via gateway_ip

Where:

  • destination_network/subnet_mask: Specifies the destination network and subnet mask in CIDR notation (e.g., 192.168.1.0/24).
  • via gateway_ip: Specifies the IP address of the gateway that should be used to reach the destination network.

Here’s an example command to add a route to network 192.168.100.0/24 via gateway 192.168.1.1:

sudo ip route add 192.168.100.0/24 via 192.168.1.1

You can verify that the route has been added by running the ip route show command:

ip route show

This will display a list of all the current routing entries on the system. The new route should be listed at the bottom of the output. (https://pragermetis.com)
