Is that possible?, I think I've read that all ipv6 interfaces by definition have
a link local address:
see section 4 paragraph 2 in URL
http://tools.ietf.org/html/draft-ietf-ipngwg-iid-00
Code:
"However, with IPv6, all (IPv6) interfaces will have a link local
address. This address is intended to allow communications over the
attached links and so is defined to be usable only on that link."
