== Delete Routes Installed by InstaGENI ==

To delete the routes automatically installed by InstaGENI on a node, you need to:
 1. Turn off all interfaces on the node except eth0.
 1. Turn on all the interfaces on the node that were shut down.

The following script will do this for you:
{{{
#!/bin/bash
#shut down the interfaces except eth0
ifconfig -a | grep eth | awk '{ if (substr($1,4,4) !=0) { print "sudo ifconfig " $1 " down"}}' |sh
#bring up the interfaces except eth0
ifconfig -a | grep eth | awk '{ if (substr($1,4,4) !=0) { print "sudo ifconfig " $1 " up"}}' |sh
}}}
A compressed tar version of this script suitable for use as an install/execute script can be [http://www.gpolab.bbn.com/experiment-support/Utilities/ClearRoutesIG.tar.gz downloaded here].

For information on adding and install/execute script to your RSpec, see [wiki:HowTo/WriteInstallScript this page].
