DESCRIPTION
This manual page documents briefly the various invocations of the iproute command. This manual page was written for the Debian GNU/Linux distribution (but may be used by others), because the original program does not have a manual page. Instead, it has documentation as part of the Linux source tree. Note that this documentation may also be found in /usr/share/doc/iproute on Debian systems.
iproute will modify or show the current policy-based routing tables. These are held in kernel space, so iproute requires root permissions to run. Note that policy based routing tables are a feature of kernels 2.1.16 and above, so you will not be able to use this program unless you have a specific patch with an earlier kernel.
OPTIONS
iproute accepts the following single options on the command line:-- -c
- Shows the current routing cache.
- -r
- Shows the current routing classes.
- -l
- Shows a long listing of routes.
Invoking the program with no command-line will produce a simple list of current routes.
SEE ALSO
route(8), ifconfig(8), netstat(8), arp(8)The policy-based routing system is documented fully in the file Documentation/networking/policy-routing.txt which can be found in kernels 2.1.16 and above.
BUGS
Not very well documented anywhere :)AUTHOR
