Play with IPv6 and is-is enough on a Cisco router, and you'll enable it 
as a matter of practice too. It's the definitive way to say "yes, this 
interface needs IPv6 active and I don't care if there's an address bound 
  or not". I forget the exact circumstances, but I ran into several 
cases where I had undesired results and needed to manually enable IPv6 
on an interface. Oh, and different versions of IOS behave differently 
towards IPv6. Imagine that.
