In fact, this point is covered in the formal spec of the Locator Option. I propose to augment it slightly thus: <t>Note 1: The IPv6 address MUST normally have global scope. Exceptionally, during initialisation, a link-local address MAY be used for specific objectives only (<xref target="secinst"/>). In this case the corresponding Discovery Response message MUST be sent via the interface to which the link-local address applies.</t> <t>Note 2: A link-local IPv6 address MUST NOT be used when this option is included in a Divert option.</t> _______________________________________________ Anima mailing list [email protected] https://www.ietf.org/mailman/listinfo/anima
