Hi Grant I think link-local is mandatory. See section 2.8 of RFC 4291. So i _guess_ you need to ensure IPv6 is not bound to the interface. It should then not have this mandatory addresses. No idea how to actually do that.... Andrew -- Before posting, please read the FAQ: http://ecos.sourceware.org/fom/ecos and search the list archive: http://ecos.sourceware.org/ml/ecos-discuss
