title: Cisco ip sla, making it more resilliant
body: <p>I have recently set up this configuration: <a href="http://pastebin.com/9SWpqQnz" rel="nofollow">http://pastebin.com/9SWpqQnz</a></p>
  
  <p>It is achieving the goal of having the route fail over to the backup ADSL line when the primary fibre ethernet line goes down. </p>
  
  <p>It is, however, failing over for a short period of time every few hours or so. </p>
  
  <p>I assume it is looking for a single missed ping?</p>
  
  <p>Can anyone suggest how this might be tightened up a bit and made more reliable?</p>
