Difficult to do in a reliable way, I'd have thought.  How do you tell  
the difference between a permanent failure (where you shouldn't  
attempt to restart the tunnel) and a transient one, such as a  
temporary network glitch while OSPF finds a new route through the  
network?  What time thresholds should you use before attempting to  
restart the tunnel?
