Route (command)

In computing, route is a command used to view and manipulate the IP routing table in Unix-like and Microsoft Windows operating systems and also in IBM OS/2 and ReactOS. Manual manipulation of the routing table is characteristic of static routing. In Linux distributions based on 2.2.x Linux kernels, the ifconfig and route commands are operated together to connect a computer to a network, and to define routes between computer networks. Distributions based on later kernels have deprecated ifconfig and route, replacing them with iproute2. Route for Linux was originally written by Fred N. van Kempen. The command-syntax is: route [-nNvee] [-FC] [] List kernel routing tables route [-v] [-FC] {add|del|flush} ... Modify routing table for AF. route {-h|--help} [] Detailed usage syntax for specified AF. route {-V|--version} Display version/author and exit. user@linux:~$ route -n Kernel IP routing table Destination Gateway Genmask Flags Metric Ref Use Iface 192.168.101.0 192.168.102.102 255.255.255.0 UG 0 0 0 eth0 192.168.102.0 0.0.0.0 255.255.255.0 U 0 0 0 eth0 192.168.103.0 192.168.102.102 255.255.255.0 UG 0 0 0 eth0 192.168.12.0 0.0.0.0 255.255.255.0 U 0 0 0 eth0 0.0.0.0 192.168.12.1 0.0.0.0 UG 0 0 0 eth0 The command is only available if the TCP/IP protocol is installed as a component in the properties of a network adapter. The command-syntax is: route [-f] [-p] [-4|-6] [Command [Destination] [mask Netmask] [Gateway] metric Metric if Interface f: Clears the routing table p: The route is added to the Windows Registry and is used to initialize the IP routing table whenever the TCP/IP protocol is started (only when used with the add command) Command: The command to run (add, change, delete, print) 4: Force using IPv4 6: Force using IPv6 Destination: Network destination of the route mask Netmask: The netmask (subnet mask) associated with the network destination Gateway: The forwarding or next hop IP address over which the set of addresses defined by the network destination and subnet mask are reachable metric Metric: Integer cost metric (ranging from 1 to 9999) for the route if Interface: The index of the interface over which the destination is reachable /?: Command help The -p parameter is only supported on Windows NT 4.
