On a similar note it reminded me of this I'd written about a year ago.  It 
brings an interface down then up if it can't ping google once as a test. 
It would crash hard if there was some billing screwup and my phone got 
shut off.  You can change the logging location to something other than 
/usr/programs/scripts/dhcp/resets.txt and the interface name.  The real 
world problem I was seeing is that if the cell phone is trying out a 
signal from a different tower that dumps the internet temporarily.  I was 
calling this from a cron job every 10 minutes.

#!/bin/bash
declare tries=0
until  (ping -c 1 www.google.com > /dev/null) || (tries > 9) ; do
  tries++
  /sbin/ifdown wlan0
  /bin/sleep 1
  /sbin/ifup wlan0
  /bin/date >> /usr/programs/scripts/dhcp/resets.txt
  if tries > 9 ; then
    echo "\nMany retries\n" >> /usr/programs/scripts/dhcp/resets.txt ;
  fi;
done

Nothing to do with routes explcitly.
