This document analyzes the security implications of using IPv6
Extension Headers with Neighbor Discovery (ND) messages. It updates
RFC 4861 such that use of the IPv6 Fragmentation Header is forbidden
in all Neighbor Discovery messages, thus allowing for simple and
effective counter-measures for Neighbor Discovery attacks. Finally,
it discusses the security implications of using IPv6 fragmentation
with SEcure Neighbor Discovery (SEND), and provides advice such that
the aforementioned security implications are mitigated.
