This document analyzes the security implications of employing IPv6
fragmentation 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 countermeasures for Neighbor Discovery attacks.  Finally,
it discusses the security implications of using IPv6 fragmentation
with SEcure Neighbor Discovery (SEND) and formally updates RFC 3971
to provide advice regarding how the aforementioned security
implications can be mitigated.

This document is a product of the IPv6 Maintenance Working Group of the IETF.

This is now a Proposed Standard.
