hmm, thanks for reporting. i personally never use anything other than
/64, and maybe that's the reason why I never see it fails...
btw, /127 assignment cannot be used in IPv6 as all-zero host address
(the last bit = 0 in /127 case) is reserved for subnet router anycast
address (RFC2367). you at least need /126 to accomodate two nodes
