You have successfully added a route on Linux using the graphical interface, your computers should now be able to talk to each other. However, is our router able to forward calls addressed to the 10.0.3.0/24 network?Ī simple “ip r” command on the router can give us a hint. In our case, in order to call the 10.0.3.2/24 IP address, the call will be forwarded to our 10.0.2.1 router. It is the default IP used by a system that failed to reach a DHCP server on the network. Note : did you know? The 169.254.0.0/16 address is called APIPA (for Automatic IP Address Addressing). In this case, it will also be sent on your local network using your default physical link. UNLESS your call is for the 169.254.0.0/16 network.In this case, it will simply be sent on your local network via your default physical link (physically a CAT network cable) UNLESS your call is for the 10.0.2.0/24 network.By default, network calls will be forwarded to the local default gateway which is 10.0.2.1.In order to understand this output, you have to read from top to bottom :

A router happens to manage many more routes than that but it is essentially using the same routing syntax. This is the routing table of your Linux computer : every computer has one. One RHEL 8 computer that will act as a simple router for our two networks.Another Ubuntu computer that has the 10.0.3.2/24 IP address.One Ubuntu computer that has the 10.0.2.2/24 IP address.The network topology has three different Linux machines : $ ip route add / via dev Īs an example, let’s say that you want two LAN networks to be able to communicate with each other. However, if you want to have a specific device, you can add it to the end of the command. $ ip route add / via īy default, if you don’t specify any network device, your first network card, your local loopback excluded, will be selected. The easiest way to add a route on Linux is to use the “ip route add” command followed by the network address to be reached and the gateway to be used for this route. If you don’t have sudo rights, you can have a look at our dedicated articles on getting administrator rights on Ubuntu or CentOS. In order to verify it, you can run the “ sudo” command followed by the “ -v” option (in order to update your cached credentials). In order to add routes on your Linux machine, you need to have administrator rights.
