In computing,
route
is a command used to view and manipulate the IProuting table in Unix-like and MicrosoftWindows[1]operating systems and also in IBMOS/2 and ReactOS.[2] Manual manipulation of the routing table is characteristic of static routing.Implementations[edit]
Unix and Unix-like[edit]
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.[3]Syntax[edit]
The command-syntax is:
Example[edit]
Microsoft Windows[edit]
The command is only available if the TCP/IP protocol is installed as a component in the properties of a network adapter.
Syntax[edit]
The command-syntax is:
Parameters[edit]
- -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 4.0, Windows 2000, Windows Millennium Edition, and Windows XP. It is not supported on Windows 95 or Windows 98.
IBM OS/2[edit]
Syntax[edit]
The command-syntax is:
Parameters[edit]
- -n: Bypasses translating IP addresses to symbolic host names
- -q: Suppresses all output
- -v: Verbose
- COMMAND: The command to run (add, delete, change, get, monitor, flush)
- -net: <dest> is a network address
- -host: <dest> is host name or address (default)
- -netmask: the mask of the route
- <dest>: IP address or host name of the destination
- <gateway>: IP address or host name of the next-hop router
ReactOS[edit]
Syntax[edit]
