Can you explain how this works?  How can a router determine which prefix 
is superfluous?  How does it cope when a suppressed prefix is withdrawn 
or a more specific prefix is added? Is this just one of those 'it works 
some of the time' solutions or is this something that can be done safely 
with an appropriate algorithm?
