Is there a reason not to advertise more specific prefixes from 2002::/16 to ensure that traffic for your v4 routes comes back to your own 6to4 router? If for example all my users have v4 addresses in 192.0.2.0/24, I could advertise 2002:C002:0000::/40 instead of or in addition to the full 2002::/16. Cheers. Mitchell
