The section "5.4.5 When Duplicate Address Detection Fails" currently says:
A tentative address that is determined to be a duplicate as described above, MUST NOT be assigned to an interface and the node SHOULD log a system management error. If the address is a link-local address formed from an interface identifier, the interface SHOULD be disabled. The part about disabling the interface enables a DOS attack: wait for a target to come on line and send a DAD packet, reply with a deliberate collision, and poof the target is disconnected from the network. Proposed resolution: write "MAY be disabled" instead. -- Christian Huitema -------------------------------------------------------------------- IETF IPv6 working group mailing list [EMAIL PROTECTED] Administrative Requests: https://www1.ietf.org/mailman/listinfo/ipv6 --------------------------------------------------------------------
