Delete Routes Installed by InstaGENI

To overcome issues faced by topologies with loops due to the way routes are installed by Instageni, you need to delete the routes. In order to delete the routes automatically installed by InstaGENI on a node, you need to do the following things.

(1) Turn off all the interfaces on the node except eth0.
(2) Turn on all the interfaces on the node that were shut down.

The following script was created to Delete Routes Installed by InstaGENI:

#!/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

The script to do this task can be found at ​http://www.gpolab.bbn.com/experiment-support/Utilities/ClearRoutesIG.tar.gz .
