IPv6 Extension Headers with Neighbor Discovery messages can be
leveraged to circumvent simple local network protections, such as
"Router Advertisement Guard". Since there is no legitimate use for
IPv6 Extension Headers in Neighbor Discovery messages, and such use
greatly complicates network monitoring and simple security
mitigations such as RA-Guard, this document proposes that hosts
silently ignore Neighbor Discovery messages that use IPv6 Extension
Headers.
