I've already mentioned in private email but will re-iterate here.  This is 
a problem caused by the CPE (the Airport in this case) not erring on the 
side of caution.  These devices really need to leave 6to4 disabled and not 
allow autoconfiguration unless they can verify there is a reachable 6to4 
relay.

Perhaps in a revised spec it can INSIST on the pingability of the 6to4 
relay so that CPEs can perform a keepalive check in determining whether to 
keep IPv6 autoconfiguration enabled.
